The study documented the earliest known interbreeding event between ancient human populations-- a group known as the 'super-archaics' in Eurasia interbred with a Neanderthal-Denisovan ancestor about 700,000 years ago. The event was between two populations more distantly related than any other recorded. The authors proposed a revised timeline for human migration out of Africa and into Eurasia. The method for analyzing ancient DNA provides a new way to look farther back into the human lineage.
Analysis of Paleolithic-era teeth from a 28,500-year-old fossil site in the Czech Republic provides supporting evidence for two groups of canids -- one dog-like and the other wolf-like - with differing diets, which is consistent with the early domestication of dogs.
New study published in PNAS shed light on some of the earliest examples of human symbolic behavior: Ancient engravings were likely produced with aesthetic intent and marked group identity.
Catfish and tilapia make up many of the animal remains uncovered in the Saharan environment of the Takarkori rock shelter in southwestern Libya, according to a study published Feb. 19, 2020, in the open-access journal PLOS ONE by Wim Van Neer from the the Natural History Museum in Belgium, Belgium and Savino di Lernia, Sapienza University of Rome, Italy, and colleagues.
Hebrew University team unearths Canaanite temple at Lachish; find gold artifacts, cultic figurines, and oldest known etching of Hebrew letter 'Samech.'
* First articulated Neanderthal skeleton to be found in over 20 years. * Discovered in famous 'flower burial' cave that sparked decades of debate about Neanderthal mortuary behaviour. * New find offers "unparalleled opportunity" to use latest techniques to understand Neanderthal "ways of death".
Cereals from the Fertile Crescent and broomcorn millet from northern China spread across the ancient world, integrating into complex farming systems that used crop-rotation cycles enabled by the different ecological regions of origin. The resulting productivity allowed for demographic expansions and imperial formation in Europe and Asia. In this study, an international, interdisciplinary team of scientists illustrate that people moved these crops across Eurasia earlier than previously realized, adapting cultivation methods for harsh agricultural environments.
How Did Dinosaur Parents Know When Their Kids Had a Fever? Prehistoric egg shells provide clues to dinosaurs' evolution from cold- to warm-blooded creatures.
In her AAAS talk, ASU researcher Katie Cramer outlines the evidence of the long-ago human footprints that set the stage for the recent coral reef die-offs we are witnessing today. Her studies have examined the origins of Caribbean coral reef declines by tracking changes over the past 3,000 years in the composition of a variety of fossils found in reef sediment cores she collected from Panama, including coral skeletons, fish teeth, urchin spines, mollusk shells, and others.
An emerging scientific consensus is that gases -- in particular carbon gases -- released by volcanic eruptions millions of years ago contributed to some of Earth's greatest mass extinctions. But new research at The City College of New York suggests that that's not the entire story.
