Digging...

...up the past. It's amazing what they find:

One of the oldest cases of tuberculosis is discovered Seven thousand years, or more, and I had the dumb luck to be born just about the time when effective treatment and prevention routines were developed!!

Discovery of 1.4 million-year-old fossil closes human evolution gap
"Humans have a distinctive hand anatomy that allows them to make and use tools. Apes and other nonhuman primates do not have these distinctive anatomical features in their hands, and the point in time at which these features first appeared in human evolution is unknown.

Now, a University of Missouri researcher and her international team of colleagues have found a new hand bone from a human ancestor who roamed the earth in East Africa approximately 1.42 million years ago. They suspect the bone belonged to the early human species, Homo Erectus. The discovery of this bone is the earliest evidence of a modern human-like hand, indicating that this anatomical feature existed more than half a million years earlier than previously known."
Remember that next time you're peeling potatoes.

Why did anatomically modern humans replace European Neandertals 40,000 years ago? They're still trying to figure out what did the Neandertals in. I maintain they are still with us. Some of them are posting comments on SNN's website.

And speaking of creepy-crawly things: Tiktaalik roseae shows signs of rear-leg development

That was long before we began dragging our knuckles.
