(Phys.org) —In the 19th century, billions of passenger pigeons crowded the skies of North America. By 1914, the birds had become extinct. Previously, ecologists thought human activity was responsible for the passenger pigeon's ...
A substantial fraction of the Neanderthal genome persists in modern human populations. A new approach applied to analyzing whole-genome sequencing data from 665 people from Europe and East Asia shows that more than 20 percent ...

(Phys.org) —Artifacts from the Middle Stone Age, which lasted from about 200,000 to 50,000 years ago, provide us with the earliest glimpses of modern human art and culture. Previously, scientists thought an increase in ...
(Phys.org) —Researchers designing adult bipedal robots have faced a challenge in limitations in a robot's walking pattern. They seek ways to improve on designs to have robots move more naturally. Improving the walking function ...
(Phys.org)—Researchers at Waseda University in Japan have built a robot rat they call WR-4, and whose purpose isto induce stress in lab rats. In studying the impact of stress inflicted on the lab rats, the researchers hope ...
(Phys.org)—A team of researchers from New Zealand and Australia has found that cultural exchange in human populations sometimes occurs at a much slower rate than genetic divergence. As the group explains in their paper ...
(Phys.org)—A US scientist has proposed that a new planetary boundary be used to analyze the effects of human activities on the planet. He warns that there are definite biophysical limits to growth in human population, economies ...
(Phys.org)—Research indicates the out-of-Africa spread of humans was dictated by the appearance of favourable climatic windows.
