Question

Quizplus · Accepted Answer

Genetic mutation and natural selection are the two mechanisms believed to be responsible for the evolution of the human brain. Genetic mutations create genetic variation, and natural selection favors beneficial mutations that enhance an organism's survival and reproduction. The human brain is believed to have evolved through millions of years of genetic mutations and natural selection, resulting in a complex and adaptable organ. Choices B, C, and D do not accurately describe the mechanisms of brain evolution.
