Robert Karl Skoglund unedited radio rant

While looking through Dateline’s webpage, this is what I read. I quote without permission: “The earliest known ancestors of modern humans might have reproduced with early chimpanzees to create a hybrid species, a new genetic analysis suggests. …Scientists can't say how long the hybridization carried on, but the final speciation occurred around 5.3 million years ago, possibly because the two species' genetic codes were too different to mix, or because the animals were simply physically unappealing to each other.”

Wow. Would this not also indicate that they didn’t have alcohol back then?
