HUMANITY MAY
HAVE ORIGINATD IN THE
WOODS
The immediate
ancestor of humans may have lived exclusively on leaves, fruits, wood and bark
instead of a menu based on open savanna as other extinct relatives of humanity did,
scientists say. The findings, published in the journal Nature, are based on two
million years fossils of the extinct hominine Australopithecus sediba.
Au-sediba’s
mix of human and primitive traits has made a strong case for it being the
immediate ancestor of human lineage. Chimpanzees, humans’ closest living
relatives, prefer fruits and leave even when grasses are abundant. By contrast,
extinct humans’ species preferred diets richer in grasses or grass eating
animals. The findings suggest there wasn’t a single, straight line from an
early, primitive hominine to humans, said study author Amanda Henry, a
paleoanthropologist at Max Planck Institute for Evolutionary Anthropology in
Leipzig, Germany.”Many of our ancestors and relatives branched out, tried new
things and generally worked at doing what was best in their environment at that
particular time,” Henry was quoted as saying by Live Science.
