Discontinuous variation is unlikely to lead to new species because
A) rapid changes are never found in the fossil record.
B) complex adaptations require multiple simultaneous mutations that work together.
C) selection cannot act on discontinuous variation.
D) it allows for only small incremental changes.

Question

Quizplus · Accepted Answer

Complex adaptations, which are necessary for the formation of new species, require multiple simultaneous mutations that work together. Discontinuous variation, which involves large and abrupt differences between individuals, is unlikely to produce these kinds of simultaneous mutations. Therefore, it is unlikely to lead to the formation of new species.
