Herschel Walker apparently isn't much of an evolution buff.The article goes on to answer the question.
"At one time, science said man came from apes, did it not?" Walker, the frontrunner for the Georgia Republican Senate nomination, said in an appearance over the weekend at a church in Sugar Hill, Georgia. "If that is true, why are there still apes? Think about it."
So, here's the deal: Humans and apes evolved from the same genetic ape ancestors, a species now long extinct. (It's known as "common descent.") We did not, however, evolve directly from the current occupants of your local zoo. They are one branch of descent from their ape ancestors. Humans are another.This is no explanation at all. Those common ancestors would be called apes. Humans have many advantages, and took over the planet. The chimps and gorillas got left behind. Why?
According to a Discover Magazine article published last month: "While we share our ancestry with these animals, along the way, over millions of years, we all changed. ... It's believed that this human divergence from the chimpanzee lineage of apes happened between 9.3 and 6.5 million years ago."
"[We] each adapted to our own environments or specific circumstances or niches," Zachary Cofran, a biological anthropologist at Vassar College, told Discover.
