Q

Race

A

-way to group and categorize people
-Category of organisms belonging to same species
-genetically distinct groups within the same species typically due to geographical distancing

Q

Pre-European colonialism

A

-People were categorized based on physical and cultural traits

Q

Binomial nomenclature

A

-7 levels systems: (Variety (optional)) Species, genus, family, order, class, phylum, and kingdom (kingdom is most broad)

17
Q

Comte de Buffon

A

-Popularized the use of the term race for Linnaeuses varieties within a species
-environmental differences are responsible for physical differences
-Believed in single origin for human kind

18
Q

Darwin

A

-Abolitionist and monogenist
-Evolution through natural selection
-Alfred Russell Wallace

19
Q

Steps for natural selection

A

1) existence of inherited variation in natural populations and species
2) populations tend to increase much faster than available resources
3) struggle for existence occurs between individuals in all pops
4) Natural selection leads to genetic changes in populations, adaptations to different environments and ultimately to the origin of new species

20
Q

Scientific racism

A

-19-20th century
-Humans can be divided through biology
-Specific markers of race
-Hierarchy in terms of race due to intelligence, abilities, beauty
-White people on top and black people on the bottom
-Robert Knox and Arthur de Gobineau
-Used darwins ideas

21
Q

Social darwinism

A

-19th century
-rejected scientific racism
-Jim crow laws around this time
-Slavery abolished, needed system to keep groups segregated

22
Q

Boas

A

-Critiqued racism
-Studied skull size and deemed it an incorrect way to differentiate race
-No connections between race
-His ideas were not accepted at the time

23
Q

Eugenis

A

-Social Darwinism leads to eugenics
-Selective breeding
-Francis Galton
-Nazi movement “race hygiene”
Due to nazi that eugenics stopped because people did not want to be affiliated with things the Nazi also did in WW2

24
Q

UNESCO

A

-1950
-Homo sapiens as a single race
-No consensus on number of races (3 was typically used)
-No scientific evidence over intelligence between races
-No genetic differences between races
-Challenged scientific racism BUT NOT RACE ITSELF

25
AAPA
-1996 -Revision of UNESCO -Pure races do not exist -Humanity cannot be classified into geographical categories -Humans share 99.9% of DNA in common
26
Glogers rule
-Darker skinned people are found near the equator and lighter near poles -Applies to animals as well -Rule is less pronounced in asia
27
Secular trend
-Humans become taller with each generation
28
Bergmann's rule
Body size is larger in colder climates
29
Allen's rule
Extremities are shorter in colder climates
30
USA demographics today
-72% white -17% Hispanic -13% black -5% Asian -1% Native American -more than 100% due to changing patterns
31
DNA
-Complex molecule in shape of double helix; carries genetic information -4 nucleotides Adenine and Thymine, Cytosine and Guanine -Nucleotides form large sequences
32
Gene
-A sequence of nucleotides along a DNA strand -differences in nucleotides sequences = genetic variability
33
Gene mutation
-Permanent alteration in DNA sequence (nucleotides sequence)
34
Alleles
-Variants of same gene eg) blood type
35
Most Dna
-Nucleus of cell, inherited through both parents
36
Mitochondrial DNA (mDNA)
-In mitochondria -only 37 genes -Inherited only through mother (haploid) -Both sons and daughters have mDNA identical to their mother's which is identical to their maternal mothers etc
37
Human haplogroups
-Show geographical patterning -Human migration patterns
38
y Chromosome
-Only in men passed down from father to son -Studied similarly to mDNA to trace male lineage
39
y chromosomial Adam
-Africa 200000 years ago; common ancestor of all living men -
40
Genetic bottlenecks
Periods when populations was small with lower density
