Researchers have extracted meaningful proteins from six teeth believed to belong to Homo erectus, offering new molecular clues about the species' relationships with other ancient hominins. The findings point to possible interbreeding with Denisovans in Asia around 400,000 years ago.

A team led by Qiaomei Fu at the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing analyzed the teeth from sites in China, including Zhoukoudian, Hexian, and Sunjiadong. The proteins came from dental enamel and revealed two key variants. One appears unique to Homo erectus, while the other matches sequences previously identified in Denisovans.

Fossil discovery in Ethiopia shows early human relatives coexisted

Researchers have found fossil teeth in Ethiopia indicating that early Homo and an unknown Australopithecus species shared the landscape between 2.6 and 2.8 million years ago. The discovery adds to evidence that human evolution involved multiple overlapping lineages rather than a single straight path.

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.

DNA study uncovers third ancestral group in Japanese population

A large-scale genetic analysis has identified a previously overlooked third ancestral group in Japan, challenging the long-held dual origins theory. Researchers linked the new ancestry to the ancient Emishi people of northeastern Japan. The findings also connect archaic DNA from Neanderthals and Denisovans to modern health conditions.

New archaeology findings reaffirm Ethiopia as human cradle

Ethiopia's Authority for Research and Conservation of Cultural Heritage announced discovery of Homo sapiens fossils from 100,000 years ago in the Middle Awash area of the Afar region. The study, led by Dr. Yonas Beyene with scientists from 24 countries, fills key gaps in Africa's human origins timeline.

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.

Paleontologists discover 275-million-year-old twisted-jaw species

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.
