'Residual echo' of ancient humans in scans may hold clues to mental disorders Researchers have produced the first direct evidence that parts of our brains implicated in mental disorders may be shaped by a 'residual echo' from Neanderthal DNA in our genomes. Evidence ...
Evolutionary biologists solve puzzle of evolutionary relationships among vertebrates Using the largest and most informative molecular phylogenetic dataset ever analysed, evolutionary biologists were able to construct a new phylogenetic tree of jawed vertebrates. This new tree resolves several key ...
In saliva, clues to a 'ghost' species of ancient human In saliva, scientists have found hints that a 'ghost' species of archaic humans may have contributed genetic material to ancestors of people living in sub-Saharan Africa today. The research adds ...
Did life begin on land rather than in the sea? A new discovery pushes back the time for the emergence of microbial life on land by 580 million years and also bolsters a paradigm-shifting hypothesis that life began, not in ...
Ancient plankton-like microfossils span two continents Large, robust, lens-shaped microfossils from the approximately 3.4 billion-year-old Kromberg Formation of the Kaapvaal Craton in eastern South Africa are not only among the oldest elaborate microorganisms known, but are ...
Big, shape-shifting animals from the dawn of time Major changes in the chemical composition of the world's oceans enabled the first large organisms -- possibly some of the earliest animals -- to exist and thrive more than half ...
DNA of early Neanderthal gives timeline for new modern human-related dispersal from Africa Ancient mitochondrial DNA from the femur of an archaic European hominin is helping resolve the complicated relationship between modern humans and Neanderthals. The genetic data provides a timeline for a ...
