Answer;

D. they have DNA within their nucleus.

Explanation;

-According to evolutionary theory, diverse groups of animals evolve from one or a few common ancestors and the mechanism by which this evolution takes place is natural selection.

-Natural selection is the process by which traits that enhance survival and reproduction become more common in successive generations of a population.

-All forms of life are built of cells. A cell is the basic unit of the structure and function of living things. Living things may appear very different from one another on the outside, but their cells are very similar.
