Um dente de 59 mil anos encontrado em uma caverna na Sibéria revela que os Neandertais perfuravam cáries para tratar a deterioração. A descoberta retrocede as origens da odontologia em dezenas de milhares de anos. Pesquisadores identificaram marcas claras de ferramentas de pedra no molar.

O segundo molar inferior foi encontrado nas montanhas Altai, no sudoeste da Sibéria. Ele apresenta três depressões perfuradas sobrepostas que atingiram a câmara pulpar. Cientistas da Academia Russa de Ciências concluíram que o trabalho foi deliberado e realizado com ferramentas de pedra pontiagudas feitas de jaspe.

Ancient DNA reveals Neanderthal group in Polish cave

Researchers have analyzed mitochondrial DNA from eight Neanderthal teeth found in Stajnia Cave in Poland, reconstructing the genetic profile of a small group that lived there around 100,000 years ago. The study, published in Current Biology, marks the first such multi-individual genetic picture from a single site north of the Carpathians. The findings show genetic links to Neanderthals across Europe and the Caucasus.

Scientists have identified a new species of ancient animal, Tanyka amnicola, from fossils unearthed in a dry riverbed in Brazil. Dating back 275 million years, this stem tetrapod featured a highly unusual twisted jaw suggesting it ground plant material. The discovery sheds light on early Permian life in Gondwana.
