In other words, there is not a particular Homo sapiens individual that researchers recognize as being the specimen that gave Homo sapiens its name. Even though Linnaeus first described our species in 1758, it was not customary at that time to designate type specimens. It is rumored that in 1994 paleontologist Robert Bakker formally declared the skull of Edward Drinker Cope as the “lectotype”, a specimen essentially serving as the type specimen. When Cope, himself a great paleontologist, died in 1897, he willed his remains to science, and they are held by the University of Pennsylvania. But a type specimen must be one examined by the original author who names a species, so Cope’s remains do not qualify.]]> 2017-06-09 18:41:31 UTC https://padlet.com/brianna_drake/n2sj6quyrsyp/wish/175913188 brianna_drake https://padlet.com/brianna_drake/n2sj6quyrsyp/wish/175913585 Where Lived: Evolved in Africa, now worldwide

The wide variability in their features suggests that Homo habilis, Homo rudolfensis and Homo erectus, the species so far identified as existing worldwide in that era, might represent a single species.

…If the three hominin species inhabiting Earth about 1.8 million years ago were collapsed into one, H. habilis and H. ruldofensis would be subsumed into H. erectus — largely owing to the similarities of the Dmanisi skulls to those known for the latter species, says Zollikofer.
