what is the difference between a gene tree and a species tree? Explain in your own words how it is possible for gorillas and humans to share a genetic trait (such as a retroviral insertion) that chimpanzees do not share, if chimpanzees and humans are really each other's closest relatives. Given the lack of agreement between gene trees and species trees, how is it possible to reconstruct the true species tree?

Primate evolution

Primates are a relatively new species and first appeared in the fossil record nearly 55 million years ago. They may have originated as far back as the cretaceous period. Their fossils were observed in North America, Asia, and Europe. Long before the first monkeys and their prosimian relatives developed, most animal species thrived and died. The first primates did not exist until about 50-55 million years ago, even though the planet is 4.54 billion years old and the first life goes back at least 3.5 billion years. Dinosaurs had been extinct for 10 to 15 million years when this happened.
