That is definitely a human lower first molar. Hopefully some kid didn't bury it in 1950 in ancient soil.
The evolutionary trend has been toward shorter jaws. Species older than **** sapiens had 4 molars. Over time, the average jaw got shorter until there were only 3 molars. We have 3 molars, but our jaws are usually too short for them, so we have to have them (wisdom teeth) extracted since they often get infected. If we keep going for another 100,000 years, we might lose that 3rd molar. That will wreak havoc with Oral Surgery practices. :laughing:I'm guessing they carbon dated the thing for the age.
The funny part of this, if the thing really is that old, the original owner of the tooth probably had some mutation where at the time his peers probably looked at him/her funny. If there was an ancient orthodontist I bet he would have been thinking boat payment.
Of course that mutation has now become the standard, evolution has to start somewhere.
