Answer:
a. Comparative molecular studies trace our earliest genetic material to Africa
Explanation:
With the development of the genetics we have been able to come to new findings or confirm some suspicions when it comes to the origin of the humans. The genetic analyses of the human DNA and the other hominids that have died out, as well as out closest ''cousins'' in the animal kingdom, have shown that the earliest human ancestors have evolved in Africa. Over time, as the conditions allowed it, the hominids started to migrate out of Africa and gradually started to settle all around the planet.
