Site in northern Spain containing the oldest known Neanderthals (430,000 YA) from DNA, originally considered Heidelberg Man fossils. These individuals were also found to have mitochondrial dna distantly related to the Denisovans. This suggests that later Neanderthals acquired their mitochondrial dna from a later population, perhaps from one migrating from Africa. These individuals have similar post-cranial skeletons as Neanderthals, but smaller brain mass relative to body mass. The only non-permafrost site that allows for DNA studies from the Middle Pleistocene. These remains have been used as a representative for archaic humans in studies on human body plans and facial growth patterns.

Human Body has Gone Through Four Stages of Evolution (2015)Edit

430 TYO fossils represent the base human body plan for the 3rd of four stages of human evolution (tall, wide, robust bodies, exclusively terrestrial bipedalism), which is shared by all homo members, until humans (taller, lighter, narrower) appeared.
