Speaking at the American Association for the Advancement of Science annual meeting in Austin, Texas, he said: "Everybody talks about Homo erectus
as a stupid apelike creature, which of course describes us just as well, and yet what I want to emphasise is that erectus was the smartest creature that had ever walked the Earth.
It appears that Homo erectus
was the first traveler.
8 million years ago likely represent representatives from one and the same species, best described as Homo erectus
But whether either of these two lineages was ancestral to Homo erectus
, let alone to modern humans, remains uncertain.

The occupants of Dmanisi "are the first representatives of our own genus outside Africa, and they represent the most primitive population of the species Homo erectus
known to date," added Lordkipanidze.
Although Homo erectus
had a brain only two-thirds the size of that of modern humans, Hrdy maintains that she was emotionally very different from the ancestors of nonhuman apes.
Later with his colleague Larnach (Larnach and Macintosh 1974, Macintosh and Larnach 1976:118) he was to withdraw his claim of a close phylogenetic link between Homo erectus
in Java and the Aboriginal Australians.
They belonged to a human ancestor known as Homo erectus
Its long arms and short legs are reminiscent of the australopithecine, which lived 2 million years ago, but its skull and teeth were much more modern, something like those of Homo erectus
, a close human ancestor.
She is thought to have lived 18,000 years ago and had a mixture of traits from an early human ancestor, Homo erectus
, and people living today.
They argue that it is most likely a descendant of Homo erectus
that evolved in long-term isolation, with subsequent endemic dwarfing.
