Oldest DNA sequences may reveal secrets of ancient animal ancestors

Researchers at Universities of Leicester and Warwick discover early conserved DNA sequences from almost 700 million years ago. 700 million year-old DNA sequences from ancient animals have been unearthed by researchers at the Universities of Leicester and Warwick, shedding new light on our earliest animal ancestors and how they influenced modern species — including the … Continue reading

New evidence emerges on the origins of life

New research shows that the close linkage between the physical properties of amino acids, the genetic code, and protein folding was likely the key factor in the evolution from building blocks to organisms when Earth’s first life was emerging from the primordial soup. In the beginning, there were simple chemicals. And they produced amino acids … Continue reading

New human ancestor discovered near fossil of ‘Lucy’

Australopithecus deyiremeda lived about 3.4 million years ago in northern Ethiopia, around the same time and place as Australopithecus afarensis. Welcome, Lucy’s neighbour. Fossilized jaws and teeth found1 in northern Ethiopia belong to an ancient human ancestor that researchers say lived around the same time as Lucy’s kind,Australopithecus afarensis, but is a distinct species. The … Continue reading

Palaeolithic remains show cannibalistic habits of human ancestors

Analysis of ancient cadavers recovered at a famous archaeological site confirm the existence of a sophisticated culture of butchering and carving human remains, according to a team of scientists. Gough’s Cave in Somerset was thought to have given up all its secrets when excavations ended in 1992, yet research on human bones from the site … Continue reading

10,000 years on the Bering Land Bridge: Ancestors of Native Americans paused en route from Asia

Genetic and environmental evidence indicates that after the ancestors of Native Americans left Asia, they spent 10,000 years in shrubby lowlands on a broad land bridge that once linked Siberia and Alaska. Archaeological evidence is lacking because it drowned beneath the Bering Sea when sea levels rose. University of Utah anthropologist Dennis O’Rourke and two … Continue reading

How 2-Million-Year-Old Ancestor Moved: Sediba’s Ribcage and Feet Were Not Suitable for Running

Researchers at Wits University in South Africa, including Peter Schmid from the University of Zurich, have described the anatomy of a single early hominin in six new studies. Australopithecus sediba was discovered near Johannesburg in 2008. The studies in Science demonstrate how our 2-million-year-old ancestor walked, chewed and moved. The fossils discovered four years ago … Continue reading

Faces of Our Ancestors

To put a human face on our ancestors, scientists from the Senckenberg Research Institute used sophisticated methods to form 27 model heads based on tiny bone fragments, teeth and skulls collected from across the globe. The heads are on display for the first time together at the Senckenberg Natural History Museum in Frankfurt, Germany. This … Continue reading
