The skeleton, along with
others of the species found so far only at Malapa, are responsible for setting off a new golden age of
early hominin fossil discovery in South Africa.
In the past year, we've learned that
early Homo sapiens interbred with
other hominins — and it's forcing us to rethink our family tree
Collins says he's also excited about
other teams producing paleoproteomic studies on cave art: The research can help us understand how
early hominins created paints by adding binding agents to ochre and
other material, which hints at their cognitive process.
Perhaps because
early humans could not easily breed with
other hominins, this would have caused an evolutionary pressure to shun those we saw as almost human.
Although
other features of their anatomy still looked primitive, the Jebel Irhoud
hominins should be considered the
earliest known members of our species, say Hublin and his colleagues.
Once
early hominins had boosted their metabolism and grown bigger brains, he says, natural selection would have favored not only fatter individuals, but also smaller guts and
other energy - saving adaptations, such as cooking and efficient walking.
Checking the types of animal bones at
other early Homo fossil sites out of Africa could show whether the mix of prey species changed when
hominins colonized a new site, supporting a «naïve prey» effect.
Although
other features of their anatomy still looked primitive, the Jebel Irhoud
hominins should be considered the
earliest known members of our species, they say.
The researchers have so far found no remains of
early humans, stone tools or
other signs of occupation, but they think that Neanderthals made the structures, because no
other hominins are known in western Europe at that time.
Our evolving chemical signature, they suggest, allowed us to outcompete
other apes and
early hominins, referring to the numerous humanlike species that arose after our split with chimpanzees over six million years ago.
But researchers have been uncovering tantalizing clues that some
other,
earlier species of
hominin, distant cousins, if you will, might have figured it out.
Over the last few decades, however, as subsequent discoveries pushed back the date for the
earliest stone tools to 2.6 million years ago (Ma) and the
earliest fossils attributable to
early Homo to only 2.4 - 2.3 Ma, there has been increasing openness to the possibility of tool manufacture before 2.6 Ma and by
hominins other than Homo.
