What is the question? I don't see the question.
<span>The answer is ‘They
are evidence that all came from a common ancestor and that life changed over
time for all these organisms’. The individuals
of the ancestor population probably spread
out and became separated b geographical features
or behavioral modification. Over time, this caused
allopatric or/and sympatric speciation. However, these species still bear
homologous structures that show this common
ancestry. </span>
According to my 9th grade biology knowledge,
The answer to this question is A: They have a recent common ancestor.
May i have choices but <span>Natural selection can take many forms. To make talking about this easier, we will consider the distribution of traits across a population in graphical form. In we see the normal bell curve of trait distribution. For example, if we were talking about height as a trait, we would see that without any selection pressure on this trait, the heights of individuals in a population would vary, with most individuals being of an average height and fewer being extremely short or extremely tall. However, when selection pressures act on a trait, this distribution can be altered.</span>
