Tetrapods (4 limbs) have very similar bone structures. This leads biologists to believe:

• They all had a common ancestor

• Their common ancestor was probably a lamprey

• Their limbs are convergent evolution

Which is artificial selection?

• Breeding dogs for specific traits.

• Coyote species diverging from the wolves.

Natural selection would select for:

• Better camouflage for hiding

• Bigger, redder, neck sack to attract females.

• Bigger antlers to beat up other deer.

• Loss of alleles.
