Face of Lucy’s ancestors revealed by 3.8 million-year-old skull in Ethiopia

Science
Aug. 28 (UPI) -- The discovery of a rare 3.8-million-year-old hominin skull unearthed in Ethiopia promises to offer fresh insights into the complexities of early human evolution. The fossil's jaw and teeth suggest it belongs to the species Australopithecus anamensis, an ancestor of the famed Lucy hominin, Australopithecus afarensis. Researchers have previously found only fragments of A. anamensis, most around 4 million years old. Until now, paleontologists surmised that A. afarensis slowly morphed into A. anamensis -- that their evolutionary relationship was linear. The latest discovery, detailed this week in the journal Nature, suggests otherwise -- that two species overlapped on the evolutionary timeline. The specimen, dubbed MRD cranium, was found at a dig site in Ethiopia's Afar Regi...

Ancient DNA gives glimpse of ancestors of Native Americans

Ancient DNA gives glimpse of ancestors of Native Americans

Technology
DNA from an infant who died in Alaska some 11,500 years ago is giving scientists the best look yet at the genetics of the ancestors of today's native peoples of the Americas. Decoding the infant's complete set of DNA let researchers estimate the timing of key events in the ancestral history of today's Native Americans and indigenous peoples of Canada and Central and South America. Expert said that while the new work doesn't radically change the outlines of what scientists have thought, it provides more detail and better evidence than what was available before. The infant girl was buried about 50 miles southeast of Fairbanks, and her remains are the earliest known in the far north of North America, said anthropologist Ben Potter of the University of Alaska Fairbanks. He reports the analysi...
