GENERAL ANTHROPOLOGY
* Study of human sort. position of all people & A ; all times * Full apprehension of what it means “to be human” * Very diverse as a species
BIOCULTURAL ANTHROPOLOGY
* Understanding relationship between biological science and civilization
HOLISTIC
* Mentioning to the whole system
* Associating to or refering the whole system instead than merely portion of the system * e. g. medicine>treatment of the whole organic structure * see all parts of the organic structure:
* religious
* cistrons
* household system
* what they eat
COMPARATIVE ( CROSS CULTURAL )
* Comparing civilizations
* No judgements made
ETHNOCENTRIC
* Belief in built-in high quality of one’s ain cultural group/culture * Tendency to see other cultural group/culture from ain position * Self-centeredness to one’s ain cultural group/culture * Stating goes “there’s no manner like the American way” * Most civilizations are by and large ethnocentric * As an anthropologist. one must be open-minded














CULTURAL “RELATIVISM”
* As an anthropologist. one must believe each other civilization has merit within its ain system * System shouldn’t be judged * Must reexamine a civilization for what it accepts
* Accept patterns that one may non O.K. of ( e. g. female Circumcision ) FIELDWORK * Time of informations aggregation
* Traveling out to the field & A ; analyzing the civilization
* e. g. taking DNA samples. research. working in the lab. etc. 4 SUBFIELDS OF ANTHROPOLOGY * Franz Boas invented the “4 Field Approach”
* Practiced in the United States
* Sometimes may overlap. all anthropology
1. Linguistic Anthropology
* Study of the linguistic communication of people. survey of communicating * Language: set of written/spoken symbols that refer to things. do it possible the transfer/knowledge from one individual to the following * e. g. 6. 000-7. 000 spoken linguistic communications in the universe * sociolinguistics: subfield of linguistics that investigate language’s societal context * societal norms of utilizing linguistic communication ( e. g. manner we talk to physician. Canis familiaris. parents ) * gender is a cultural stereotype put on a individual due to their sex * work forces and adult females have different utilizations of address 2. Cultural Anthropology ( Sociocultural )







* Culture-learned behaviour that’s distinguishable amongst a group of people * Passed down through coevalss * Evolutionary ; alterations
* Estimated 5. 000 distinguishable cultural groups on the planet
* Different degrees of civilization & A ; sublevels
* North vs. South vs. Midwest vs. Northeast
* Analyzing behaviour
* Kinships. household. friends. nutrient. faith. etc.
* Specialize in different countries
* Medical anthropology: how civilizations treat diseases
* Political anthropology: difference in power
* Economic anthropology: survey of goods & A ; resources
3. Archeology
* Study of the stuff remain of past human life & A ; activities * Artifacts: material objects from past civilizations ( e. g. tools. clayware. ceramics ) * Ecofacts: natural stuff used by worlds * Features: artifacts/ecofacts that can non be removed from their context * Excavation & A ; lab work * Very systematic & A ; controlled because what one uncovers. one besides destroys * e. g. shipwreck: artefacts found in the H2O are preserved. when it’s taken above sea. artefacts are being destroyed in the procedure * certification is indispensable * Fortes: any clip period including but limited to classical archaeology & A ; contract archaeology * Contract V. Academic * Biggest difference: required by jurisprudence to halt building if artefacts are found & amp ; contact archeologists * Contract
under budget. clip. jurisprudence constraints 4. Biological Anthropology











* Study of human biological development & A ; human biocultural fluctuation * Evolutionary significance of fluctuation * Unheard of to happen a about complete dodo
AMERICAN ANTHROPLOGY
* Franz Boas
* Turn of the twentieth century
* “Father of Anthropology” ( invented the 4 Field Approach ) * Trained the first coevals of well-known anthropologists * Set the criterion on how anthropology should be studied in America * Came up with biocultural position * Ales Hrdlicka



* Worked at the Smithsonian
* Most good known for his involvement in the skull
* Founded the American Journal of Physical Anthropology ( 1918 ) * “Voice of the Field” * Besides founded the American Association of Physical Anthropology ( 1929 ) * Charles Darwin * “History of Evolutionary Thought”

* His created thoughts:
* Speciess Change ( Evolution )
* Complied information to turn out his thought
* Adaptive Radiation
* Out of one species branches multiple related species
* Idea that populating things can fall from a common ascendant * Gradualism * That alteration occurs gradually/slowly
* Species will germinate easy over many coevalss
* Natural Selection
* Recognizes the impact of the environment on life organisms HISTORY OF EVOLUTIONARY THOUGHT * Middle Ages in Europe
* 2 thoughts that dominated the worldly position
* Order: natural hierarchal agreement or order to life
* Stasis: thought that things do non alter ( inactive )
* Influenced by. created by. & A ; perpetuated by spiritual beliefs * Idea
of the “Great Chain of Being” * At the top. there was a “Great Being/Supreme Being” * Besides impacted the natural universe ; wasn’t merely spiritual * Gradually increased to most religious existences ( dirt>angels ) * Fixity of species: mentioning to stasis ; one time things were created. they were fixed * Applied to worlds and the natural universe * Political System












* Related to hierarchy: monarchy were at the top of the order * Static: no 1 could travel up the concatenation of bid * Thoughts mirrored in political system
* Young Earth
* At the clip. everyone believed the Earth was merely 5. 000 old ages old alternatively of 1000000s of old ages old * Hence the name “Young Earth” * No 1 of all time dared to travel against the constituted system

* 14th-18th Centuries
* Ideas easy began to alter due to the Renaissance & A ; the Enlightment * Revival of all these Fieldss of survey * Technological progresss
* Microscope
* Telescope
* Began to recognize that the universe was everlastingly traveling
* “Earth is non the centre of the universe”
* Printing imperativeness
* Allow speedy spread of ideas/information
* Exploration
* Increased travel outside of Europe
* Encountered diverse lands & A ; people
* Brought to life all the diverseness of the planet










DARWIN’S INFLUENCES
* Carolus Linnaeus
* Created the binomial terminology: classifying beings with a two-name system * became the footing for modern taxonomy * Buffon
* Botanist in the King’s garden
* First to compose how the environment influences organisms * However. did non believe that one species could alter into another * Lamarck *
If an being was in demand. it could modify itself to run into the demand & A ; the alteration can be passed on to the following coevals * “inheritance of acquired characteristics” or Lamarckism * Features that are acquired during a life-time of an person can be inherited by his/her offspring * e. g. the giraffe’s cervix grew as a consequence of seeking to accommodate to making higher foliages * organisms experiences emphasis in the environment that causes them to accommodate & amp ; this adaptation is passed on * Lamarck falsified ( non true ) * Lamarck’s thoughts can be explained by epigenetic




* Chemical reactions that turn cistrons on/off harmonizing to the environment & A ; can be passed down from coevals to coevals * Cuvier * Well-respected. comparative anatomist
* Paleontologist
* Noted extinct fossils & A ; wanted to explicate this
* Catastrophism: periodic calamities that would bechance the Earth & A ; cause mass extinction * Life signifiers from other parts would repopulate that peculiar country * e. g. temblors & A ; tsunamis * calamities were represented in dodos


* Lyell
* Geologist: known as the laminitis of modern geology
* Uniformitarianism: geological processed that impact the Earth have been unvarying throughout clip * Same thing at work in the present were besides at work in the past * As a consequence. the landscape of Earth is invariably altering & As ; really old * Malthus * Economist. reverend

* Demographer: survey of population ; birth/death rates
* Idea that population size is limited by the resource handiness & A ; because of this. there will be competition among people for those limited resources * Arguing about population control * “The Essay on the Principle of Population”

* Alfred Wallace
* Naturalist & A ; learned bookman
* Independently came up with the thought of natural choice ( thought that the
environment can impact beings ) * Corresponded with Darwin * Deserves merely every bit much recognition & A ; praise as Darwin


* Charles Darwin
* Influenced by biological science. natural scientific disciplines. anthropology
* From a affluent household
* Became knowing about the current events
* Sailed around the universe on “The Beagle” ( for 5 old ages ) where he collected informations from the trip * By 1858. Wallace was traveling public. but Darwin didn’t want Wallace to have all the recognition * Origins of Species ( 1859 ) : Darwin’s book on natural choice * Caused a immense splash in society NATURAL SELECTION



* “Survival of the Fittest”
* Not needfully about physical fittingness. more so about engendering * Breeding for certain traits occurs of course based on the environment * Basic Processes * Biological fluctuation
* Competition
* Something will go on to do people vie for limited resources * Peoples with advantageous traits will last * High decease rate
* Selective force per unit area: any circumstance/phenomenon that affects the generative success of an being in an environment * Determines which traits will be more advantageous * Fitness: step of generative success



* How many offspring one have & amp ; how many of those offspring can hold offspring * e. g. adult male in his 50’s had 4 childs & A ; 15 grandkids. he has more fittingness than the adult male in his 80’s who merely had 1 grandkid * Reproduction * Passed cistrons on to wining coevalss

* Shift advantageous traits
* Those without the advantages will decease off
* Accretion
* Assuming selective force per unit area remains changeless
* Traits will be more common ; lessening in unfavourable traits * Trait
will roll up over clip * Population: group of people
* Measured in the population through alteration is by the single * New Species? * May develop new species over clip. but doesn’t have to * Change in frequences of different traits * 23 different definition





* Contrast between Darwin & A ; Lamarck
* Lamarck says that camelopard will “grow” their cervixs to run into a certain demand & A ; these traits are so passed on * Darwin says in a giraffe population. there’s a fluctuation of cervix lengths & A ; over clip. the cervix length of the camelopard will increase because those with shorter cervixs will decease off through natural choice * Medium Ground Finch Example * Biological fluctuation in the beak size

* At first. the finches ate soft seeds that were easy to interrupt unfastened * Increase in beak size when there was a drouth ( selective force per unit area ) * Smaller. softer seeds became unavailable so the finches had to trust on another nutrient beginnings which were harder seeds * Persons with larger beaks were able to check unfastened the seed ( advantageous trait ) * The finches with larger beaks were more able to last & amp ; reproduce. which in bend created big beaked finches & A ; changed the average beak size * Peppered Moths Example * In the early 1800’s. gray moths were legion because they were able to camouflage with the natural environment so they were less preyed on * Because of pollution. black moths were more camouflaged with the environment while gray moths were preyed on more ( displacement in population ) * Antibiotic Resistance * Penicillin was introduced in WWII & A ; people were lasting due to mend infections * 1947 ( 4 old ages after ) . mutant bacteriums were organizing that were opposition to penicillin * Bacteria reproduces so rapidly ( 15-20 proceedingss ) so natural choice occurs more rapidly & amp ; immune mutations form faster * Multiple Resistant Tuberculosis ( MDRTB ) * Bacteria-induced disease

* Would kill one from the interior out
* Starts in the lungs
* Antibiotics made TB scarce
* But now. there’s extremely immune signifiers of Terbium
* Resistant to two or more premier drugs used to handle TB
* Methicilin-Resistant Staphylococcus Aureaus ( MRSA )
* Found in infirmaries
* Can last in several types of antibiotics
* Cause infections through unfastened lesions. weak immune system * Kills more people in the US than AIDS does * Increase hospital deceases in those that have it than those who don’t * Antibiotics kill 98 % of bacterium. but 2 % of bacteriums are still alive & A ; adapt to the drugs & A ; base on balls on the opposition to the following coevals * Key Things in Natural Selection * Environment







* Trait must be passed on ; able to inherit
* Fitness ( generative success ) : acquiring cistrons in the hereafter & A ; # of offspring who will last to reproduce more offspring INHERITANCE * Homunculus: means “Little Man”
* Proposed that in sperm cells. at that place existed a bantam but fully-formed small individual * Little individual would merely acquire bigger * Blending heritage
* Children were a blend/mix of their parents. 50-50 mix of each parent * e. g. ruddy flower + white flower = pink flower * Mendel’s worth with pea workss proved the “Little Man” theory & A ; intermixing heritage do non work * Cells * Basic unit of life


* Prokaryotic: comparatively simple beings with no karyon ( like bacteriums ) * Eukaryotic: contains nucleus ( DNA ) & A ; cell organs ( sub-nuclear membrane edge components/bodies that do some map in the cell ) * Cell Types * Somatic cells: do up organic structure tissues. bone cells. gristle. etc. * Gametes reproduction cells ( sperm & A ; egg ) that contain familial codification from the parents DNA * Genetic stuff

* 2 ironss of bases ( sugar+phosphate+base )
* Bases ( A. G. C. T )
* Base-pair specificity
* Adenine with T. G with C
* Reproduction
* Development. growing. care. fix
* Important that they replicate precisely
* Constantly go oning
* Nuclear DNA ( nDNA )
* Nucleus of every cell except ruddy blood cells
* Thousands of cistrons. one million millions of base braces
* Template for protein production
* Blueprint for life
* Homoplasmic: same in every cell irrespective of cell type * Mitochondrial DNA ( mtDNA ) * Found in chondriosome. which produces energy for cell to work * 37 cistrons ( much smaller sections of DNA ) * Aids with mitochondrial map ( production of energy ) * Heteroplasmic: non indistinguishable in every cell ; can be different because chondriosome can retroflex & amp ; segregate HEREDITY * Gene: sequence of Deoxyribonucleic acid












* Structural: a cistron that’s responsible for organic structure constructions codifications for activities that enable life * Regulatory: regulates the maps of other cistrons ; turns them on/off * Homeotic cistron ( Hok cistron ) * Guides embryological development

* In many different life signifiers ( birds. mammals. reptilians. etc. ) * Genes can be long or short with bases * Chromosomes
* Worlds have 46 chromosomes
* Sequence of cistrons
* Karyotype: organized profile of a person’s chromosomes * Autosomes ( 44 ) * Carry familial information on physical features. but don’t determine primary sex features * Sex chromosomes ( 2 ) * Determine the primary sex feature


* XX ( female ) . XY ( male )
* Offspring receives 23 chromosomes from each parent
* Homologous braces ( 23 )
* Pair of chromosomes that each chromosome carries the same information * Almost the same size & A ; carry the same trait coding but aren’t indistinguishable * Carry familial codification for the same traits CELL DIVISION


* Mitosis
* Creates 2 girl cells
* Identical to each other & amp ; original
* Diploid figure intending they all have 46 chromosomes
* Occurs for growing & A ; development. tissue fix. organic structure care * Meiosis * Goes through two rhythms
* Leads to gametes ( sex cells )
* Recombination/crossing over occurs> exchange of familial stuff between homologous chromosomes * 4 girl cells that aren’t indistinguishable to each other or original * Haploid figure intending they have half the # of chromosomes. so they have merely 23 chromosomes * Gamete development * Important because recombination allows for fluctuation which is cardinal to natural choice CELL DIVISION MISTAKES * Deletion of chromosomes. etc.





* Nondisjunction
* Failure of chromosomes to divide during miosis
* Creates daughter cells with the wrong figure of chromosomes * Monosomy: one less chromosome in a brace ( merely have 1 alternatively of 2 ) * Can go on to autosomes which is more tragic & A ; can be fatal * XO Turner Syndrome: monosomy in sex chromosomes * Have merely 1 Tens but are females

* Have 45 chromosomes alternatively of 46
* Won’t putting to death you
* Trisonomy: 3 chromosomes in a brace alternatively of 2
* Highly variable scope of impact
* In somatic chromosomes ( no Ten or Y )
* T21-Down Syndrome
* Extra 21 chromosomes
* Could hold malfunction in the bosom. etc.

* Growth lack
* Death in approximately 6 months
* T13- Patou
* Merely survive in a few yearss
* In sex chromosomes ( have X or Y )
* Xxy: more feminine features in a male because of more Ten * Thirty: taller but normal birthrate with possible larning disablements * Xyy: taller. lower sperm count. larning disablements MENDELIAN TRAITS













* Worked with pea workss ( tallness & A ; colour )
* Genetic Principles
* Law of Segregation: traits are controlled by distinct units that occur in braces * The braces separate during gamete formation & A ; reunited during fertilisation * Therefore. each parent contributes one of the braces to the offspring * Gene/Allele * Gene: sequence of DNA responsible for some map

* Allele: alternate signifier of a cistron
* Dominant: described as an allele that’s expressed in the presence of another different allelomorph ( T ) * Recessionary: described as an allelomorph that’s non expressed in the presence of another different allelomorph ( T ) * Locus: location of an allelomorph on a chromosome * Homozygous: two transcripts of the same allelomorph ( TT )

* Heterozygous: different allelomorphs present ( Tt )
* Genotype: combination of allelomorphs or familial make-up ( TT ) * Phenotype: physical look of allelomorphs ( tall. short. etc. ) * Punnet Square ( see notes for illustrations ) * Law of Independent Assortments

* Genes that codification for different kind independently from each other * Variety of offspring * Some cistrons go together ( linkage. cistrons are passed together ) * e. g. ruddy hair & A ; lentigos * Inheritance in Humans

* Mendelian Inheritance: heritage of traits controlled by allelomorphs at one venue * a. k. a. Mendelian traits * over 18. 000 of them
* either nowadays or non
* Examples:
* Earlobes: attached ( recessionary ) vs. unattached ( dominant ) * Earwax: waxy. gluey ( dominant ) vs. dry. flaky ( recessionary ) * PTC Paper Test: taste tester ( dominant ) * Hair line: widow’s extremum ( dominant ) vs. heterosexual
( recessive ) * Thumb: hitcher’s pollex ( dominant ) vs. no crook ( recessionary ) * Blood type * Alleles codification for antigens on the surface of the blood cells ( A. B. O ) * Types: A. B. O * O is recessionary. A & A ; B are co-dominant in AB



* Type A blood is either AA or AO
* Type B blood is either B or BO
MENDELIAN DISORDERS
* Dominant: one transcript of harmful allelomorphs means you have the upset * Acondroplasia ( nanism ) * Brachydactyly ( shorter/different finger lengths )
* Recessionary: must hold two transcripts of harmful allelomorphs to acquire matured upset * Sickle cell anaemia. Tay Sachs. Cystic Fibrosis * Carriers: person who carries one of the allelomorphs that causes the upset * Heterozygote look: one allelomorph is non wholly masked POLYGENIC INHERITANCE * Tend to be uninterrupted in their look



* Range of variation/expression
* Skin colour. tallness. form of eyes. oculus colour
* Inheritance of traits controlled by allelomorphs at more than one venue * Skin colour * Melanin production
* Multiple venue part
* Co-dominant allelomorphs
* Polygenic traits
* Environmental influence
* Has less effects on Mendelian traits
* Can’t alteration blood types
* More impact on polygenic traits
* Height ( environment can stunt growing )
* Pleiotrophy
* One cistron impacting multiple traits
* Complicated procedure
MODERN THEORY OF EVOLUTION
* Development: alteration in familial frequences of a trait in a population over clip * Production & A ; distribution of familial fluctuation * Natural
choice ( environmental influence )
* Microevolution
* Small graduated table alterations in a population
* Below the species level
* Macroevolution
* Large graduated table alterations that occur at or above the species level * Not observed during a short clip * Occurs over 1000s of coevalss
* Difference in non one of the procedure. but of the graduated table of the alteration * Series of microevolution can take to a macroevolution * Deme: group of beings that interbreed on a regular basis & A ; produce offspring ( a. k. a. population ) * Gene pool: all familial information in a deme * Hardy-Weinberg Equilibrium





















* Mathematical equation that predicts allele distribution in a population under the ideal conditions * Tools used to measure if the population allelomorphs are altering * Ideal conditions: changeless environment. all mate & A ; have the ability to bring forth offspring INFLUENCES ON ALLELE FREQUENCIES * Mutation

* Change in DNA sequence
* Spontaneous: of course happening
* Induced: non natural. but induced by the environment
* Creates fluctuation. which can be passed on
* Gene Flow: motion of allelomorphs between populations
* Crossbreeding
* Creating fluctuation
* Genetic Drift: alterations in allele frequences caused by random events * Bottleneck Effect * Reduction possible in familial fluctuation
* Something drastic happens & A ; the population is all of a sudden reduced * e. g. Hurricane Katrina * Founder Effect
* Start with a group of persons who goes & A ; establishes a settlement someplace else * Genetic fluctuation with the laminitiss of the new settlement * e. g. Ellis Von Syndrome
* Recessionary upset
* Causes nanism & A ; polytactism ( excess fingers )
* Occurs at higher rates among the Amish because it’s a close population with a high birth rate * Can be traced to one of the laminitiss * Difference of Bottleneck & A ; Founder consequence is where you begin * Bottleneck is with a big population * Founder is with a little. closed population











* Natural Selection
* Balanced polymorphism ( Heterozygote Advantage )
* Maintenance of 2 or more allelomorphs in a population due to selective advantage of the heterozygote * Get selected out & A ; have an advantage * Sickle Cell Allele
* Recessionary upset
* Found in equatorial Africa & A ; parts of India
* Deformed red blood cells because it deforms haemoglobin
* Causes anaemia. hurting. & A ; decease
* Malaria
* Disease caused by parasite that onslaught red blood cells
* Connection between Malaria & A ; Sickle Cell
* If you’re homozygous normal. you’re more apt to acquire malaria> fittingness goes down * Carriers of reaping hook cell are protected from malaria because the parasite can’t reproduce * Both homozygous phenotypes aren’t good. but being a bearer is good * Same relationship between Tay-Sachs upset & A ; TB * Carriers of Tay-Sachs are protected from TB * As good as the relationship between cystic fibrosis as a defender against cholera HUMAN VARIATION * “Voyages of Discovery” ( 15th-17th Century )









* Traveling out to detect the universe
* Meeting difference in worlds
* Monogenism: all worlds were posterities of a individual original brace & A ; any fluctuation in worlds is due to environmental fluctuation * Polygenism: fluctuation in worlds is a consequence of different original braces * Early Studies ( early 18th-19th Century ) * Describing & A ; sorting fluctuation

* People categorized based on discernible characteristics like tegument. caput form. etc. * Word “race” came into being * No consensus on figure of races & A ;
what constituted race * Mid nineteenth Century * Biological determinism

* Behavioral properties are governed or associated with biological properties * Just because you look a certain manner means you’ll act a certain manner * Today. people still think with that sort of mentality RACE

* Common definition
* Speciess: as in the human race
* Cultural/ethnic individuality
* Religious individuality
* Physical features
* “Ethnicity” & A ; “Ancestry” are used as a replacement for race * Some argue “race” doesn’t exist * Problems:
* Racism
* Not about how you look. but how people assign intending to how you look * One group is superior over another * Not dependable manner to separate people
* There will ever be many outlooks
* Entire populations can non be categorized
* Genetic fluctuation
* More fluctuation within a population subgroup than there’s between different subgroups * More genetically similar than they are different * Definition from biological anthropology position










* One polytypic species
* Geographic form to phenotype fluctuation
* Cultural association with biological effects
* Peoples who portion common imposts. linguistic communication. belief systems. etc. married other people similar to themselves * Cline * Refers to gradual phenotype or familial fluctuation over geographic infinite * Don’t draw boundaries * “there are no races on the planet. merely clines”


HUMAN VARIATION
* Environmental emphasis
* Rain. temperature. height
* Humans response to environmental emphasis
* Cultural: behavioural alteration in response to emphasize * Wearing a coat because it’s cold * Compensate for force per unit area on your organic structure
* Acclimatization ( Physiological )
* Individual response to an environment force per unit area. but it’s nonvoluntary * Reversible & A ; short term ( impermanent ) * e. g. tan. addition in ruddy blood cell production in high heights. addition in sudating * Developmental * Happens at single degree. but is discernible at population degree * Ability to react to emphasize is inherited * Response occurs during a critical period of growing & A ; development * Not reversible. non short term * e. g. high height populations have larger Black Marias. thoraxs. & A ; lung capacity. different O transit * Genetic ( Population ) * Qualify a population





* Inherited. long term. non-reversible
* Occurs at birth because it’s inherited
* “the adaptation”
* e. g. tegument colour
* happens regardless of specific circumstance of the single * Purpose? To Maintain Homeostasis * Ability of being to keep internal equilibrium
* Food. H2O. temperature
SOLAR RADIATION & A ; SKIN COLOR
* Darker tegument colour in equatorial parts where there’s more solar radiation * All worlds have same # of meloncites. but different in how much they produce * Melanin protects from UV radiation * More melanin of course > can defy more UV visible radiation






* Hence tegument pigmentation is protection from solar radiation * In an country where solar radiation is greater. those who have more melanin will hold the advantage & A ; better fittingness * Vitamin D Hypothesis * The body’s need for vitamin D and for UV radiation to bring forth it provided a selective force per unit area for lighter tegument in the northern latitudes * Less pigmentation ( at northern latitude ) = better vitamin D synthesis TEMPERATURE EXTREMES * Over 120 grades to -60 grades is the temperature scope for endurance *
We respond better to heat than to cold * Heat

* Sweating: response to extreme heat ( body’s manner of seeking to chill us down ) * Vasodilatation: capillaries at skin’s surface dilate * Moving blood off from the nucleus & A ; out towards the surface * e. g. musculuss turn pink when exerting * Cold

* Chill: automatic response
* Trying to bring forth heat
* Burns a batch of foods
* Vasoconstriction: capillaries near the skin’s surface constricts * Decrease blood flow to come up of your tegument * Keeps critical variety meats bathed in blood & A ; warm
* Could lead to decease in tissues like cryopathies
* Body Metabolic Rate ( BMR )
* Colder clime people have higher BMR than those in warmer climes * Bergmann’s & A ; Allen’s Rule * Pattern/general relationship between clime & A ; organic structure size/shape * Bergmann’s Rule: organic structure size will increase as distance from the equator decreases * Allen’s Rule: limb length decreases as distance from the equator increases OTHER ADAPTATIONS * Adapting to high heights





* Hypoxia: status that develops when you don’t acquire adequate O * “oxygen starvation”
