A species is:

• the process of turning into a human

• a group of organisms of the same kind (in one or more populations) that do not reproduce with organisms from any other group

• the process by which species adapt to environmental changes over a very long time

• the process by which one population evolves into two or more different species

An ancestor is:

• a related organism from a previous generation

• a more recent species that evolved from an ancestor population

• a part of an organism

• Having died out completely and no longer alive anywhere on Earth

Why do cats and giraffes have similar body structures.

• These species are not related

• It was a coincidence, that can't happen

• They share a common ancestor

• They both had the same mother but it was a giraffe
