Ancient dental plaque tells tales of Neandertal diet and disease

upper jaw from Neandertal
Calcified dental plaque from the upper jaw of a young Neandertal male from El Sidron cave in Spain reveals insights into his vegetarian diet and dental health problems.

Dental plaque preserved in fossilized teeth confirms that Neandertals were flexible eaters and may have self-medicated with an ancient equivalent of aspirin.

DNA recovered from calcified plaque on teeth from four Neandertal individuals suggest that those from the grasslands around Beligum’s Spy cave ate woolly rhinoceros and wild sheep, while their counterparts from the forested El Sidron cave in Spain consumed a menu of moss,…

Human genes often best Neandertal ones in brain, testes

Neandertal brain
BRAIN ACTIVITY Human versions of some genes are more active in certain parts of the brain than Neandertal versions. Side and back views of a brain show that activity levels of the Neandertal version of a gene called NTRK2 are lower in the cerebellum (blue area in lower back) than in other regions.

Humans and Neandertals are still in an evolutionary contest, a new study suggests.

Geneticist Joshua Akey of the University of Washington in Seattle and colleagues examined gene activity of more than 700 genes in which at least one person carried a human and a Neandertal version of the gene. Human versions of some genes are more active than Neandertal versions, especially in the…
