Investigadores han extraído proteínas significativas de seis dientes que se cree pertenecen al Homo erectus, lo que ofrece nuevas pistas moleculares sobre las relaciones de esta especie con otros homínidos antiguos. Los hallazgos apuntan a un posible cruce con los denisovanos en Asia hace unos 400.000 años.

Un equipo dirigido por Qiaomei Fu, del Instituto de Paleontología de Vertebrados y Paleoantropología de Pekín, analizó los dientes procedentes de yacimientos en China, incluidos Zhoukoudian, Hexian y Sunjiadong. Las proteínas provienen del esmalte dental y revelaron dos variantes clave. Una parece ser exclusiva del Homo erectus, mientras que la otra coincide con secuencias identificadas previamente en los denisovanos.

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.

Ancient DNA uncovers complex kin relations in Swedish Stone Age graves

Researchers at Uppsala University have used ancient DNA to reveal that Stone Age burials in Sweden involved extended family members beyond immediate relatives. Analysis of shared graves at the Ajvide site on Gotland shows second- and third-degree kin were often buried together, suggesting strong community ties. The findings challenge assumptions about simple family structures in hunter-gatherer societies 5,500 years ago.

Neanderthal infants grew faster than modern human babies

A new analysis of the best-preserved Neanderthal infant skeleton shows that these ancient babies developed bones and brains at a pace matching modern humans aged 12 to 14 months, despite being only about six months old. The findings, based on the Amud 7 infant from Israel, suggest Neanderthals grew rapidly in early childhood as an adaptation to harsh environments. Researchers observed similar patterns in other young Neanderthal remains.
