Some organisms, such as a chimpanzee and a human, have many similarities. Others, such as a chicken and an oak tree, have fewer similarities. What is TRUE about the ancestors of these organisms?
- Chimpanzees and humans share a common ancestor with each other, but chickens and oak trees do not share a common ancestor with each other.
- Chimpanzees and humans share a common ancestor with each other, and chickens and oak trees share a common ancestor with each other, but chimpanzees and humans do not share a common ancestor with chickens and oak trees.
- Because chimpanzees, humans, chickens, and oak trees are separate species, none of them shares a common ancestor with any other.
