Pollen analysis suggests peopling of Siberia and Europe by modern humans occurred during a major Pleistocene warming spell
A new study appearing in Science Advances compares Pleistocene vegetation communities around Lake Baikal in Siberia, Russia, to the oldest archeological traces of Homo sapiens in the region. The researchers use the ‘remarkable evidence’ to tell a compe…
Probing the deep genetic structure of Africa
Using ancestry decomposition techniques an international research team has revealed a deeply divergent ancestry among admixed populations from the Angolan Namib desert. This unique genetic heritage brings the researchers closer to understanding the dis…
Jellyfish, with no central brain, shown to learn from past experience
Even without a central brain, jellyfish can learn from past experiences like humans, mice, and flies, scientists report for the first time. They trained Caribbean box jellyfish (Tripedalia cystophora) to learn to spot and dodge obstacles. The study cha…
