Arm Structure

APBIO-TX4EJG

A bat wing, a primate arm, and the front leg of a cat all have similar bone structures: one bone attached at the shoulder, two bones in the forearm, a series of wrist bones, and digits.

Based on this evidence what conclusion can be drawn?

A

Cats, bats, and primates evolved in similar environmental conditions.

B

Cats, bats, and primates have common ancestor with the same bone configuration.

C

Gene flow has occurred between cats, bats, and primates.

D

Natural selection favored this bone configuration in a variety of animal groups.
