The correct answer is Humans and chimpanzees have DNA that is very similar because they both evolved from a common ancestor.
Explanation:
Both humans and chimpanzees are primates; this means both species belong to the same biological order (rank in taxonomy). Moreover, humans and chimpanzees share most of their DNA (around 99%). This indicates the two species are related and they evolved from the same ancestor. This implies a primate that existed million years ago (common ancestor) was the origin of these two species and due to this common ancestor they share most of their DNA; however, as both species changed separately the remaining DNA is different and this makes both species look and be different. According to this, the correct statement about the evolution of primates is "Humans and chimpanzees have DNA that is very similar because they both evolved from a common ancestor."

Explanation:
Hi, fellow AP Human Geographer. Basically, all that arithmetic density means the total number of people per unit of land area. Having said that, we can immediately eliminate A. because increasing the population would only increase the total number of ppl. per unit of land area. Next, B. B can work, theoretically; however, there is a better answer. Next, D. D. says limiting the number of farmers; while this will technically reduce the number of ppl. per unit of land area, again there is a better answer. Next, E. I'd say this is the toughest choice; however, by increasing the area of urban areas, it can end up attracting more people instead. Overall, the best answer would be C., limiting the size of the population.
