Question 11

How was the distribution of humans (after they evolved)affected by continental drift?

Accepted Answer

A)  The supercontinent of Pangaea had not yet split up before humans evolved. This made it very easy for humans to travel over the entire landmass of Earth. 
B)  The supercontinent of Pangaea had already begun to split up, but the continents were still very close together, making it easy for humans to travel from one continent to another. 
C)  The supercontinent of Pangaea had not yet split up before humans evolved. This had little impact on the distribution of humans because they did not travel until the 1400s. 
D)  The supercontinent of Pangaea split apart and the resulting continents were in their present-day locations by the time modern humans evolved. This would have slowed the distribution of humans until they developed ways of easily traveling the oceans.

Question 12

Mass extinctions cause the loss of many species,no matter how well adapted those species were before the extinction.Why might previous adaptations NOT help a species survive a mass extinction?

Accepted Answer

A)  The rapid environmental changes that cause mass extinctions do not leave the organisms time to adapt. 
B)  Ongoing continental drift allows more species to interbreed, which lowers the genetic variability available for adaptation. 
C)  Adaptive radiations are stronger than adaptations. 
D)  Well-adapted organisms will not be affected by mass extinction; these are the groups that will survive.
