Flashcards in Nov 25 Deck (26):
How did transitional humans look?
ape-like proportions w/ bipedal gait
What type of diet did transitional humans have?
Transitional humans co-existed w/ which Homo species?
The linear evolution model explains human evoltion
Transitional humans (made/used) fire
What were the longest living hominins?
H. ergaster and erectus
What aspect of human evolution supports the punctuated equilibrium model?
transition from habilis to erectus
What is the ancestor of H. neanderthalensis
What is unique about Middle Eastern H. neanderthals?
What 3 regions were neanderthals found?
N. Africa, Europe, Middle East
How old are neanderthals?
200-30 thousand yrs old
What evidence supports the theory that neanderthals blended w/ humans?
many nuclear loci from Neanderthals found in humans of European and Asian origin
What does the multiregional continuity model state?
H. erectus populations independently evolved with gene flow into H. sapiens
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
non-African genomes are what percent Neanderthal?
What is part 2 to the out of africa model?
-‐H. erectus expansion and (mostly) isolated
-‐H. sapiens migration and intermixing with other hominins
Which species concept conflicts with the leaky replacement model?
Which early human made fire?
Which early human was the 1st to wear clothes and develop language?
What was H. floresiensis? Was it a different species from humans?
What does the FOXP2 regulatory gene control?
How many amino acid substitutions are there in the FOXP2 regulatory gene btw chimps and humans?
Is cultural inheritance in humans genetic?
How much time do humans spend feeding relative to chimps?
How much time do humans spend feeding relative to their body size?
LESS than similar-sized species
