Something I&#x27;ve never understood (since highschool some 30 years ago) is; when getting partial skeletons perhaps from only a single individual, how can they claim new species? I mean what&#x27;s diff with that and some hypothetical future anthropoligist looking at siberian with roundish skull thicker brow ridges and that of six foot tall masai with long face and then a sub 5 foot native peruvian and declaring them all different species?
