CALGARY—In 2010 paleoanthropologists announced to great fanfare that they had recovered from a South African cave two partial skeletons of a previously unknown member of the human family that lived nearly two million years ago. The skeletons—a young male and an adult female referred to as MH1 and MH2, respectively–were said to exhibit a striking melange [...]

Sex with Neandertals Introduced Helpful and Harmful DNA into the Modern Human Genome

Neandertal skull

Over the past few years a number of studies of ancient and contemporary genomes have reached the same stunning conclusion: early human species interbred, and people today carry DNA from archaic humans, including the Neandertals, as a result of those interspecies trysts. Now two new analyses of modern human genomes are providing insights into how [...]

Wow. I’ve just spent the last couple days going through the paleoanthropology news that broke in 2013 and I must say it was a banner year. There were so many exciting new findings that bear on scientists’ understanding of just about every chapter of humanity’s seven-million-year saga—from our ancestors’ first upright steps to the peopling [...]

Morwood, who passed away on July 23 from cancer, made important contributions in research areas ranging from the rock art of Australia’s Kimberly region to the seafaring capabilities of Homo erectus. But he will be best remembered for a [...]

Space Ape Parody Shows Why Aquatic Ape Theory Is All Wet

This past weekend the misguided aquatic ape theory surfaced for air, only to get sunk in the most entertaining way.  The theory holds that many traits of humans—including our naked skin, upright posture and large brains–evolved as adaptations to living in an aquatic environment. But fossil and archaeological evidence simply does not support this scenario, [...]

Is Australopithecus sediba the Most Important Human Ancestor Discovery Ever?

Australopithecus sediba

Three years ago researchers added a new branch to the human family tree: Australopithecus sediba, a nearly two-million-year-old relative from South Africa. By all accounts it was a dazzling find—two partial skeletons, an adult female and young male, from a site called Malapa just outside Johannesburg. And it has been making headlines regularly since then [...]

Last fall, on a reporting trip to Johannesburg for a story on the discovery of fossils representing a previously unknown member of human family called Australopithecus sediba, the researchers I met with were buzzing with excitement about, of all things, tartar. That’s right, the crusty deposits that the dentist scrapes off your teeth when you [...]

Was Australopithecus sediba Polygamous? Paleontologist Answers Reader Questions about New Early Human Fossils

Lee Berger

During a recent reporting trip to South Africa for a forthcoming feature article on a new fossil human species called Australopithecus sediba, I asked readers to submit their questions about this dazzling find. Inquiries about the nearly two-million-year-old hominin–which has been held up as a possible ancestor of our genus, Homo–came in via Twitter, Google Plus [...]

Is This Your Long-Lost Ancestor?

Australopithecus sediba skull

In the spring of 2010, the world met Australopithecus sediba, a nearly two-million-year-old human relative whose remains were found at a site just a short drive from Johannesburg, South Africa. By all accounts, it was an extraordinary discovery: two beautifully preserved partial skeletons–a juvenile male and an adult female–with the promise of more individuals to [...]
