The great reproductive success of Homo erectus was fostered by all of the following adaptations EXCEPT
|
symmetrical brains

tall stature
|
|
|
Which of the following is associated only with modern Homo sapiens?
|
Art
|
|
|
By around 20,000 ya, and probably earlier, humans had populated every landmass except for
|
Antartica
|
|
|
Based on current available evidence it appears that fully modern looking people first appeared about
|
160,000 ya
|
|
|
What question do the African Replacement model and the Multi-regional Evolution model try to answer?
|
When did Homo sapiens originate?
|
|
|
In the lumper-splitter debate, which model do the lumpers prefer?
|
Multi-regional Evolution model
|
|
|
Which of the following is part of the African Replacement model?
|
Modern looking Homo sapiens spread over the Old World from Africa, replacing archaic populations when they came in contact.
|
|
|
Which of the following is part of the Multi-Regional Evolution model?
|
The physical features we associate with modern humans appeared everywhere but may have been manifested in different ways.
|
|
|
One conclusion of the multi regional evolution model is that, if premodern groups are in fact member of our species, then the rules of taxonomy dictate that the earliest name used for any of them must be applied to them all. Thus if all six species of Homo are indeed the same species they would all be

Homo sapiens

refute the AR model and support the MRE model
