Generation Gaps Suggest Ancient Human-Ape Split

We aren’t the only primates with a big generation gap. Human parents are, on average, a whopping 29 years older than their kids. That had been considered unusually long for a primate, but a new study reveals that chimpanzees and gorillas have their own large generation gaps, about 25 years and 19 years, respectively. The findings also indicate that our ancestors split from those of chimpanzees at least 7 million to 8 million years ago, more than 1 million years earlier than previously thought... news.sciencemag.org
