New insights into the late history of Neandertals
Researchers at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, have sequenced the genomes of five Neandertals that lived between 39,000 and 47,000 years ago. These late Neandertals are all more closely related to the Neandertals that contributed DNA to modern human ancestors than an older Neandertal from the Altai Mountains that was previously sequenced. Their genomes also provide evidence for a turnover in the Neandertal population towards the end of Neandertal history. (2018-03-21)

Mapping the gut microbiome to better understand its role in obesity
Several recent science studies have claimed that the gut microbiome -- the diverse array of bacteria that live in the stomach and intestines -- may be to blame for obesity. But Katherine Pollard, Ph.D., a senior investigator at the Gladstone Institutes, says it is not that simple. (2015-02-13)

The ancient history of Neandertals in Europe
Parts of the genomes of two ~120,000-year-old Neandertals from Germany and Belgium have been sequenced at the MPI for Evolutionary Anthropology. The analyses showed that the last Neandertals, who lived around 40,000 years ago, trace at least part of their ancestry back to these European Neandertals that lived around 80,000 years earlier. The 120,000-year-old Neandertal from Germany, however, carried some ancestry that may originate from an isolated Neandertal population or from relatives of modern humans. (2019-06-26)
