Root Of Man Found in Canal

You may have noticed, but I love prehistory. We know so little about where man actually came from, and because there's so little archaeological evidence surrounding early man every time something new is discovered it's very exciting. So, as you might guess, I was super stoked when earlier this week archaeologists announced that nearly a year ago they dug up two 9.7 million year old teeth in Germany that changes all previous theories about the origins of man.

Before I start, I have to say that these teeth weren't actually found in a canal, they were found in the Rhine Riverbed. Which makes it even more amazing that despite being buried in dirt for millions of years, the teeth were in good condition. According to the scientists on the project, they look like they could have been pulled yesterday.

One of the teeth. Kinda gross, but really cool.

According to Herbert Lutz, the lead author for the study, these teeth show similar characteristics to teeth previously found in hominids, the generally supposed precursors to man. What makes these teeth so interesting is their location. All previous bones and fossils of this age have been found in Africa or the Mediterranean areas. There aren't a lot of fossils found in Central Europe, and certainly not near the Rhine. It had been previously supposed that hominids were centralized in Africa and the Mediterranean area, but the finding of these teeth suggest hominids may have lived farther north as well.

Though two teeth might not seem like a big find, they're a big deal when it comes to learning about early man. The wear marks on the teeth will be able to help historians guess at the diet of these early people, and analysis of the enamel can help guess the age of the owner.

The reason that archaeologists waited so long to release their find is because these teeth completely overthrow everything previously known about the evolution of man, and they wanted to be 120% sure before telling McGraw-Hill to start rewriting their textbooks. However, a year later they are confident enough in their dating to release the find.

This article leaves me with many questions, and, I'll admit, I've been having fun speculating about the answers. My biggest question though-- why have this primate's teeth have lasted for 9 million years, when I have 357 new cavities every time I go to the dentist?¹


¹I'm just kidding, of course. Obviously those teeth are fossilized, and the differences between the prehistoric diet and the diet of a modern day chocolate addict are vastly different.
