Describe three or more genetic mechanisms that may lead to the rapid evolution of a new species. Which of these genetic mechanisms are influenced by natural selection, and which are not?
Which of the following statements is not true about the concept of natural selection?
Group of answer choices
A-Geographical isolation contributes to the formation of new species as individuals begin to adapt to different environments
B-Natural selection explains the increase in the yield of kernels per corn plant over the last several thousand years
C-Infers that later generations may be distinct from ancestral ones, or a new species can appear
D-Selective pressures cause distinct species to develop
E-Suggests that over long periods of geological time, successful variations accumulate in a population
