Interview: The DNA of Human Evolution

Then they observed the earth today and how they would have lived back then. Later she began to compare human DNA to chimp DNA since they are out closest relative. When she finished her studies she found out that the human and chimp genome lined up. She ended up finding that sequencing of humans and chimps were very close to each other.
