Attention to the Unseen

By Cecilia Padilla-Iglesias This article was originally published on SAPIENS As a university student in the early 2010s, I recall how beautifully simple our origin story was: Homo sapiens evolved in East African savannas around 150,000 years ago. Then, sometime around 70,000 years ago, a mutation occurred that endowed these individuals with the capacity for complex, symbolic behavior. This set them apart from any other species and allowed them to leave Africa and take over the world, replacing all other humans they encountered….

ZME Science reports: In the plains of western Ukraine, researchers digging through ancient soil found a handful of small, broken pieces of ivory that might change how we think about early humans. The fragments—24 in total—came from the tusks of a long-extinct mammoth species. Most were unremarkable at first glance. But as scientists studied them more closely, they noticed patterns and shapes that didn’t seem like they had been accidentally broken. Some pieces had been chipped in a way that…

University of Michigan: Ancient Homo sapiens may have benefited from sunscreen, tailored clothes and the use of caves during the shifting of the magnetic North Pole over Europe about 41,000 years ago, new University of Michigan research shows. These technologies could have protected Homo sapiens living in Europe from harmful solar radiation. Neanderthals, on the other hand, appear to have lacked these technologies and disappeared around 40,000 years ago, according to the study, published in Science Advances and led by…

The New York Times reports: Chimpanzees live only in African rainforests and woodlands. Orangutans live only in the jungles of Indonesia. But humans live pretty much everywhere. Our species has spread across frozen tundras, settled on mountaintops and called other extreme environments home. Scientists have historically seen this adaptability as one of the hallmarks of modern humans and a sign of how much our brains had evolved. But a new study hints that maybe we aren’t so special. A million…

ZME Science reports: Across the dense forests of the Congo, the sunlit islands of the Pacific, and the icy reaches of the Arctic, the few remaining hunter-gatherers have thrived thanks to their astonishing athleticism. A new study led by George Brill and colleagues from the University of Cambridge reveals that hunter-gatherer societies worldwide practiced an extraordinary range of locomotory behaviors. These include walking, running, swimming, diving, and climbing. One of the most intriguing findings was that men and women across…

Science Alert reports: A “provocative” new piece in Nature has proposed a whole new group of ancient humans – cousins of the Denisovans and Neanderthals – that once lived alongside Homo sapiens in eastern Asia more than 100,000 years ago. The brains of these extinct humans, who probably hunted horses in small groups, were much bigger than any other hominin of their time, including our own species. Paleoanthropologist Xiujie Wu from the Chinese Academy of Sciences (CAS) and anthropologist Christopher Bae from the University of Hawai’i…

Excavating the new trackway site, with footprints from hominins, birds and other animals visible in foreground. Neil Roach By Anna K. Behrensmeyer, Smithsonian Institution; Kevin Hatala, Chatham University, and Purity Kiura, National Museums of Kenya Human footprints stir the imagination. They invite you to follow, to guess what someone was doing and where they were going. Fossilized footprints preserved in rock do the same – they record instants in the lives of many different extinct organisms, back to the earliest…

This finger bone discovered in Siberia in 2008 led to the original Denisovan discovery. Wikimedia, CC BY-SA By Linda Ongaro, Trinity College Dublin It started with a finger bone found in a cave in the Altai mountains in Siberia in the late 2000s. Thanks to advances in DNA analysis, this was all that was required for scientists to be able to identify an entirely new group of hominins, meaning upright primates on the same evolutionary branch as humans. Now known…

Megan Scudellari and Mark Belan write: A surprising discovery about human evolution began with a research study about, surprisingly, birds. Five years ago, evolutionary biologist Laura van Holstein at the University of Cambridge read a study on the role of competition in songbird evolution. The work, from an international team of evolutionary biologists, found that competition between interacting species of songbirds—over food, mates, and territory—drove the evolution of new traits, such as beak shape, across long timescales and large distances…
