Many researchers outside of Berger’s group think the Malapa hominids couldn’t be genus most likely evolved in eastern Africa.“The Malapa line may have died out as a failed experiment in how to evolve an upright stance and humanlike features,” Stringer says. He questions whether those few fossils that Stringer refers to, dating to shortly before fossils.

Many researchers outside of Berger’s group think the Malapa hominids couldn’t be genus most likely evolved in eastern Africa.“The Malapa line may have died out as a failed experiment in how to evolve an upright stance and humanlike features,” Stringer says. He questions whether those few fossils that Stringer refers to, dating to shortly before fossils.Found in 1994, it consists of just an upper jaw and palate (part of the mouth). Berger now says this fossil may be much younger than the 2.3-million-year-old soil its discoverers claim it came from.Researchers generally agree that hominids evolved into No one knows precisely when that happened.

The Malapa cave’s skeletons are the most complete finds from this muddled period.

In 2010, Berger’s team identified these fossil folk as members of a previously unknown species. Moreover, he claims, these fossils establish southern Africa as where the big evolutionary action was. But Berger’s South African finds have renewed interest in the muddle in the middle, notes Susan Antón.

Hoping to find them, Berger and his colleagues resumed digging at Malapa last September.

They suspect the site holds at least three more hominid skeletons. The 2-million-year-old story of anthropology The study of humankind.evolve To change gradually over generations, or a long period of time.fossil Any preserved remains or traces of ancient life.

What’s more, he argues, the Ethiopian jaw and palate may simply be too few bones to demonstrate that they come from a . That’s the evolutionary story with the strongest fossil support, de Ruiter says.

He comes to that conclusion mainly from studying the Malapa skeletons and the skeleton of an before 2 million years ago could fit in a shoe box — along with one shoe,” de Ruiter says.The cave sits within the Malapa Nature Reserve in South Africa.In 2008, 9-year-old Matthew Berger was exploring the cave when he spotted a bone sticking out of a chunk of rock.A storm soon washed their bodies into a lake or pool within the cave.Wet soil rapidly hardened around the bodies, protecting their bones.Scientists have dug up few hominid fossils from that stretch of time.For that reason, researchers call early evolution “the muddle in the middle” of the hominid family tree.She’s a paleoanthropologist at New York University in New York City.She predicts that “For the next decade, questions about the origins of the genus will be in the forefront of hominid research.”Berger never thought that hominids in southern Africa nearly 2 million years ago would look anything like the Malapa individuals he unearthed. And the reason: They look like an odd mix of later species, ones belonging to the also possessed a relatively narrow, humanlike pelvis and lower rib cage. Relatively narrow and apelike, it fanned out like an inverted cone.This the nearly 2-million-year-old skull of a young boy found in the Malapa cave.Some scientists are arguing that its species is the most direct ancestor of what would evolve into the genus containing humans.
