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.
The discovery of a new species of prehistoric reptile from Germany is reported this week in Scientific Reports. The anatomical features of the species, named Vellbergia bartholomaei, add to our understanding of the early evolution of lepidosauromorphs.
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.
A group of Russian and German palaeontologists have described a previously unknown genus and species of prehistoric salamanders. The new amphibian is named Egoria malashichevi -- in honor of Yegor Malashichev a talented scientist and associate professor of the Department of Vertebrate Zoology at St Petersburg University, who passed away at the end of 2018.
Researchers at Uppsala University and the University of Leeds presents a new mathematical model of patterns of diversity in the fossil record, which offers a solution to Darwin's "abominable mystery" and strengthens our understanding of how modern groups originate. The research is published in the journal Science Advances.
Paleodietary studies of the fossil record are impeded by a lack of reliable and unequivocal tracers. Scientists from the MPI for Evolutionary Anthropology, the MPI for Chemistry and the Johannes Gutenberg University (JGU) in Mainz have now tested a new method, the isotope analysis of zinc isotopes from the tooth enamel of fossil mammals, and found it to be well suited to expand our knowledge about the diets of fossil humans and other Pleistocene mammals.
The mystery surrounding dinosaur footprints on a cave ceiling in Central Queensland has been solved after more than a half a century. University of Queensland palaeontologist Dr Anthony Romilio discovered pieces to a decades-old puzzle in an unusual place - a cupboard under the stairs of a suburban Sydney home.
Science Snapshots: Dinosaur blood vessels, giant viruses, and antibiotic-building enzymes.
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.
The left and right side of the brain are involved in different tasks. This functional lateralization and associated brain asymmetry are well documented in humans. Scientists now challenge the long-held notion that the human pattern of brain asymmetry is unique. They found the same asymmetry pattern in chimpanzees, gorillas, and orangutans. However, humans were the most variable in this pattern. This suggests that lateralized, uniquely human cognitive abilities evolved by adapting a presumably ancestral asymmetry pattern.
