Which of the following statements best describes what will most likely occur to the moth populations in the image above?

b)

It provides evidence of gradual change in species over time.

DNA sequences are identical in all organisms.

b)

DNA shows that all species are unrelated.

c)

DNA provides a record of evolutionary changes.

c)

He found evidence that all species were created simultaneously.

d)

He concluded that species do not change over time.

12.

What is the importance of homologous structures in evolutionary biology?

What is the role of genetic drift in evolution?

a)

It causes large populations to evolve rapidly.

b)

It has no effect on small populations.

c)

It leads to random changes in allele frequencies in small populations.

d)

It always increases genetic diversity.

15.

How can embryology provide evidence for evolution?
