Flashcards in Nov 25 Deck (26):
1

How did transitional humans look?

ape-like proportions w/ bipedal gait

2

What type of diet did transitional humans have?

mixed diet

3

Transitional humans co-existed w/ which Homo species?

H. erectus

4

TRUE/FALSE
The linear evolution model explains human evoltion

FALSE

5

Transitional humans (made/used) fire

only used

6

What were the longest living hominins?

H. ergaster and erectus

7

What aspect of human evolution supports the punctuated equilibrium model?

transition from habilis to erectus

8

What is the ancestor of H. neanderthalensis

Homo heidelbergensis

9

What is unique about Middle Eastern H. neanderthals?

post-date humans

10

What 3 regions were neanderthals found?

N. Africa, Europe, Middle East

11

How old are neanderthals?

200-30 thousand yrs old

12

What evidence supports the theory that neanderthals blended w/ humans?

many nuclear loci from Neanderthals found in humans of European and Asian origin

13

What does the multiregional continuity model state?

H. erectus populations independently evolved with gene flow into H. sapiens

14

What does the out of African model state?

H. erectus populations spread and were isolated with zero gene flow-->H. sapiens emerged from Africa, overran H. erectus with zero gene flow

15

non-African genomes are what percent Neanderthal?

2%

16

What is part 2 to the out of africa model?

-­‐H. erectus expansion and (mostly) isolated
evolution
-­‐H. sapiens migration and intermixing with other hominins

17

Which species concept conflicts with the leaky replacement model?
a) phylogenetic
b) phenetic
c) biological

c) biological

18

Which early human made fire?

H. erectus

19

Which early human was the 1st to wear clothes and develop language?

neanderthals

20

What was H. floresiensis? Was it a different species from humans?

hobbits
YES

21

What does the FOXP2 regulatory gene control?

language

22

How many amino acid substitutions are there in the FOXP2 regulatory gene btw chimps and humans?

2

23

Is cultural inheritance in humans genetic?

NO

24

How much time do humans spend feeding relative to chimps?

LESS

25

How much time do humans spend feeding relative to their body size?

LESS than similar-sized species

26

How do SNPs shows convergent evolution in high-population species?

similar SNP profiles in EGLN (oxygen sensing) and HIF (hypoxia inducible transcription factor) genes in distinct high altitude populations
