Question

Which of the following is not part of the theory of natural selection?
A) Individuals in a population vary.
B) Some variation can be passed on to offspring.
C) Populations produce more offspring than the environment can support.
D) All species are descended from a common ancestor.

Accepted Answer

The theory of natural selection does not include the idea that all species are descended from a common ancestor. This is a concept known as common descent, which is supported by evidence from multiple fields of biology such as comparative anatomy, molecular biology, and paleontology but is not a central part of the theory of natural selection.
