This story has the vibe of a TED talk, it's got scientists with different opinions, a grand scope and scale of tens of thousands of years, plus dogs, which we all love.<p>I really do think humans were doing interesting things tens of thousands of years ago. Some of it was written down, and some of it only survives through oral traditions but the ideas and actions of those people in that era still impact us today.<p>Some of those things are animals like the cat that is trying to sit on my laptop right now.
