Question

Which of the following is true about large brains?

Select one:

a. A large brain is an energetically cheap adaptation.

b. Large brains are evolutionarily compatible with bipedality and require no adaptive trade-offs.

c. Due to our large brains we develop independence faster than our smaller-brained ape cousins.

d. The evolution of large brains in hominins is related to their highly derived feeding ecology (relative to other African apes).

e. Humans have relatively large guts compared to other hominids, which allows us to process a wider range of food to power our large brains.

Answer 1

Option B is correct. Larger brain is responsible for more Cognitive skills. Development of bipedality need more fine skills. Larger brains are evolutionary compatible with bipedality
