Facial Reconstruction of Homo georgicus, Skull nº D2700 from Dmanisi Republic of Georgia (~1.8 Mya) 

  • Reconstruction by Philippe Froesch

This reconstruction is rather different than those seen in the previous post. The nose is much narrower and the nostrils are much less flared. The supraorbital torus is less prominent, the eyes are light and the skin much fairer too. It also seems less prognathic but it’s hard to tell from these angles. You don’t often see a reconstruction of any hominid dating to ~1.8 Mya that looks this modern human caucasian-like. However, Homo erectus was all over the shop and certainly variability existed. Here are some examples of other reconstructions, this one (Dmanisi), this one (Dmanisi), this one (Homo erectus) and  this one (Homo erectus). See also this image for comparisons of different reconstructions of the Dmanisi specimens. I wonder about variability both in artistic but scientifically informed representation and on a geographic basis in fossil specimens. And I’m aware that I’m conflating taxa here because as today’s guest post noted, there is no consensus as to the taxon of the Dmanisi fossils.

I love facial reconstruction…and well physical anthroplogy. WIN!

Mind-Controlled Devices

Led by Bin He, Ph.D., director of the Biomedical Functional Imaging and Neuroengineering Laboratory, the team has created a non-invasive brain-computer interface (BCI) that could one day restore mobility and independence for individuals with amputated limbs, paralysis and other impairments that prevent or limit normal movement. With the help of this interface, volunteers have been able to precisely control the flight of simulated and small model helicopters using only their minds.
