Which scenario is the least likely to be supported by the theory of evolution?
| a. All species that have ever lived are genetically related. | | |
| b. Pigs, dolphins, bats, and humans share a common ancestor. | | |
| c. Humans evolved from chimpanzees. | | |
| d. Dogs were domesticated from their gray wolf ancestor. | | |
| e. Repeated exposure to DDT can lead to pesticide resistance in mosquitos. | |
c. Humans evolved from chimpanzees .
This is because genetic evidence suggests that though humans and chimps are closely related, chimps do not represent our ancestors and both the groups have diverged about 4.4 m.y ago but have a common ancestor.
Recent evidence suggests that the fossil Ardipithecus ramidus (4.4 m Y)may have been our common ancestor but walked neither like chimps nor like humans and had intermediate form of walking.
