Homo erectus: Ancient humans survived longer than we thought

Science
An ancient relative of modern humans survived into comparatively recent times in South-East Asia, a new study has revealed.Homo erectus evolved around two million years ago, and was the first known human species to walk fully upright.New dating evidence shows that it survived until just over 100,000 years ago on the Indonesian island of Java - long after it had vanished elsewhere.This means it was still around when our own species was walking the Earth.Details of the result are described in the journal Nature.In the 1930s, 12 Homo erectus skull caps and two lower leg bones were found in a bone bed 20m above the Solo River at Ngandong in central Java. In subsequent decades, researchers have attempted to date the fossils. But this ...
Origin of modern humans ‘traced to Botswana’

Origin of modern humans ‘traced to Botswana’

Science
Scientists have pinpointed the homeland of all humans alive today to a region south of the Zambesi River.The area is now dominated by salt pans, but was once home to an enormous lake, which may have been our ancestral heartland 200,000 years ago.Our ancestors settled for 70,000 years, until the local climate changed, researchers have proposed. They began to move on as fertile green corridors opened up, paving the way for future migrations out of Africa."It has been clear for some time that anatomically modern humans appeared in Africa roughly 200,000 years ago," said Prof Vanessa Hayes, a geneticist at the Garvan Institute of Medical Research in Australia."What has been long debated is the exact location of this emergence and sub...
Humans stored bone marrow for delayed consumption 400,000 years ago

Humans stored bone marrow for delayed consumption 400,000 years ago

Science
Oct. 11 (UPI) -- Paleolithic humans stored animal bones for as long as two months before eating the marrow. The discovery -- published this week in the journal Scientific Advances -- suggests early humans were practicing food storage and delayed consumption as early as 400,000 years ago. The evidence was recovered in Qesem Cave, a Lower Paleolithic archeological site located outside of Tel Aviv, Israel. "Bone marrow constitutes a significant source of nutrition and as such was long featured in the prehistoric diet," Ran Barkai, a professor of archaeology at Tel Aviv University, said in a news release. "Until now, evidence has pointed to immediate consumption of marrow following the procurement and removal of soft tissues. In our paper, we present evidence of storage and delayed consumpti...
Humans were altering the planet as early as 2000 B.C.

Humans were altering the planet as early as 2000 B.C.

Science
Aug. 30 (UPI) -- According to a new study, the Anthropocene began some 4,000 years earlier than previously thought. Archaeological data suggests humans were responsible for significant land-cover changes as early as 2000 B.C. The Anthropocene is the current geological age. It is described as the period in which human activity has been the dominant influence on Earth's climate and the environment. Some scientists contend the Anthropocene began during the late 19th or early 20th century, as the industrial revolution transformed the global economy. Others have argued the epoch began when nuclear weapons testing began altering the atmosphere. But the latest research contends the geological age began much earlier. "The activities of farmers, pastoralists and hunter-gatherers had significantly...
Extinction: Humans played big role in demise of the cave bear

Extinction: Humans played big role in demise of the cave bear

Science
The arrival of human ancestors in Europe some 40,000 years ago coincided with the downfall of the cave bear, scientists have revealed.New evidence suggests humans hunted the bear and drove it from caves, putting it on the road to extinction.The fate of the species was sealed by other pressures, such as the onset of the last Ice Age, and shrinking food resources.The bear eventually died out 24,000 years ago."We see this dramatic drop in the population of the cave bear starting from 40,000 years ago, which coincides with the arrival of anatomically modern humans in Europe," said Prof Verena Schuenemann of the University of Zurich, who led the study."It is the clearest evidence we have so far that humans might have played a big role...
