Their studies of the forest chimpanzees of West Africa suggest that for explanations of the physical and social
characteristics of our earliest hominid forbears we should look at forests and woodland, not bush and grassland (New Scientist, Science, 19 May 1990).
Ongoing excavations at Dmanisi, a site in the Republic of Georgia, have yielded scores
of early hominid fossils, including five skulls and, most recently, a complete male pelvis found in 2014.
The co-author on the paper, Dr. C. Owen Lovejoy, is a Distinguished Professor of Anthropology at Kent State University, well known for his reconstructions of the socioecology and locomotor
behavior of early hominids such as «Ardi» (Ardipithecus ramidus, 4.4 million years old) and «Lucy» (Australopithecus afarensis, 3.2 million years old).
He imagines one
group of early hominids, in one zone, who had been elevated to soul and had a direct experience of God which resulted in the subjugation of nature and matter to the spirit.
These data suggest that the anatomy and behavior
of early hominids did not evolve in response to open savanna or mosaic settings.
This and corroborative evidence from fossil assemblages of avian and small mammals imply that a grassland environment was not a major force driving
evolution of the earliest hominids.
For decades, before the
diversity of early hominids in Africa became apparent, many researchers believed that humanity's most likely direct ancestor was East Africa's Australopithecus afarensis, best known through the famous 3.2 - million - year - old Lucy.
He hinted that gestural theory could clear up another mystery about this period as well: why the stone
tools of these early hominids show little evolution for almost two million years, despite increases in brain size.
Having an accurate time scale is a crucial aspect of reconstructing how anatomical and behavioral characteristics
of early hominids evolved.
«This opens up the potential for us to learn more about the vocal
capacities of early hominids that lived before the split between the orangutan and human lineages to see how the vocal system evolved towards full - blown speech in humans.»
It features two partially fused roots, a trait
characteristic of early hominids but not ancient apes, a team led by geoscientist Jochen Fuss of the University of Tübingen in Germany reports May 22 in PLOS ONE.

Morphology of Early Hominids (General Australopithecus, Paranthropus, Orrorin), and Overview by J.H. Schwartz and I. Tattersall.
In this inherited malady, the brain is typically just 400 cc — roughly the same size as
that of the early hominid Australopithecus africanus, of which «Lucy» is the best - known specimen.
Owen Lovejoy, a paleoanthropologist at Kent State University, has spent his career studying the fossils
of early hominids.
«The body proportions of modern humans are wildly different from
those of early hominids, and that confounds the whole thing,» says University of Utah evolutionary biologist Dennis Bramble.
Among several similarities of Graecopithecus teeth to
those of early hominids, partial fusion of the second premolar root stands out, the researchers say.
Most of the senior members of the Chorora research team also belong to the Middle Awash project team that has recovered the fossil remains of at least eight hominid species, including
some of the earliest hominids, spanning nearly 6 million years.
