Protein in Homo erectus Teeth Indicates Denisovan DNA Inherited by Modern Humans
Researchers identified a distinct form of the tooth enamel protein ameloblastin in Homo erectus samples from China that also appears in Denisovans and some modern human populations. The study examined ancient proteins from teeth approximately 400,000 years old, bypassing DNA degr…

Proteins From 400,000-Year-Old Teeth in China Yield First Data on Homo Erectus
Researchers recovered substantial preserved proteins from six teeth assigned to Homo erectus at three Chinese sites, revealing two enamel protein variants shared by all specimens. One variant appears unique to East Asian H. erectus while the second is also found in Denisovans and…

Study Finds Minor Changes in Average Japanese Skull Shape Over Past Century
CT scans of people who died between 1900 and 1920 compared with those who died between 2022 and 2024 show skulls have become more brachycephalic, with shorter foreheads, larger mastoid processes and increased sexual dimorphism. Shiori Usui attributes the changes to improved child…

Andean Populations Show Genetic Adaptation to Potato-Rich Diet
Indigenous communities in the Andes domesticated potatoes between 6,000 and 10,000 years ago, leading to genetic changes that persist in their descendants. A new study found that Quechua speakers in Peru have an average of 10 copies of the AMY1 gene, which produces an enzyme that…

Neandertals Used Rhinoceros Teeth as Tools at Sites in Spain and France
Researchers identified marks on fossilized rhinoceros teeth from caves in Spain and France that indicate Neandertals used them as hammers and anvils around 100,000 years ago. The teeth served multiple purposes including shaping stone tools and processing vegetable fibers and hide…

Genetic Study Suggests Human Population Once Dropped to 1,280 Breeding Adults
The current global human population exceeds 8 billion. A recent genetic study indicates that the human population may have declined to approximately 1,280 breeding adults at some point in the past. The study examines genetic evidence to support this finding.

Human Genetic Mutation Rate and Its Effects on Fitness Examined in New Scientist Column
A column in New Scientist discusses the human genetic mutation rate, which some researchers have linked to declines in physical and mental fitness. Columnist Michael Le Page argues that these mutations do not pose the health risks often attributed to them. The piece explores whet…
