Question

examine the evolutionary diagram below what does the diagram imply about the peafowl and field mouse?

a. they share a remote common ancestor
b. they did not evolve from older forms of life
c. they are unrelated
d. they share a recent common ancestor

Explanation:

进化树中，孔雀（Peafowl）和鸡（Chicken）有共同祖先“Early Bird”，田鼠（Field Mouse）和鼠（Rat）有共同祖先“Early Mammal”，而它们又都有更古老的共同祖先“Early Vertebrate”。这说明它们有一个遥远的共同祖先。选项B错误，因为所有生物都从更古老的生命形式进化而来；选项C错误，它们有共同祖先所以是有联系的；选项D错误，它们的共同祖先不是近期的。

Answer:

A. They share a remote common ancestor
