Jan Bartek - AncientPages.com - A new study challenges established views on human skull evolution. Researchers suggest that brain growth and the reduction of the face and jaw may b...
Evolutionary psychology is known to explain dark parts of our nature, like homicide. But it also sheds light on prosocial behaviors, like love.
The lead author is John Hawks, a professor of anthropology at the University of Wisconsin–Madison, who has a popular blog on paleoanthropology. Source
Human body size evolution was shaped by both gradual change and a major later growth spurt within Homo. When did our ancestors become human-sized? Scientists have debated for decad...

Why do we have big brains? Or walk on two legs? Biological anthropologist and broadcaster Alice Roberts talks human exceptionalism, evolution and her new book Humans with Michael M...
How do we explain all the “mind-boggling sweep” of time-consuming behavior that isn’t directly necessary for survival? Source
A new study, published July 6, 2026, in the journal Nature Communications, suggests that two of the best-known trends in human evolution—brain growth and the reduction in the size...
The human hand is an evolutionary marvel. While other primates rely on their hands for locomotion and basic grasping, ours can shape tools, manipulate objects, and perform detailed...
For most of the 20th century, the model of human origins was a tree: with the trunk dividing into branches, and then twigs. Each species of human relative (hominin) was a neat, sin...
New PNAS research on 386 fossils shows human body size jumped later within the genus Homo rather than growing steadily across the whole family tree
A new Yale-led study provides one of the most detailed and comprehensive analyses to date of genetic variation in human populations in Oceania, filling a major gap in representatio...
Learn how fossils show human ancestors did not grow bigger in a straight line, but split into larger and smaller evolutionary paths.
JOHANNESBURG, SOUTH AFRICA—According to a statement released by the University of the Witwatersrand, gum disease […] The post Periodontal Disease May Have Influenced Human Evolutio...
New research shows migratory predators can link the evolution of species thousands of miles apart, even when those species never share the same territory
Biologists group animals with similar traits into broad categories called orders. Despite their similarities, animal species in the same order can have very different average lifes...
A 4.4-million-year-old fossil called Ardi is reshaping human evolution genetics. A 2025 Communications Biology study reveals she climbed like an The post The 4.4-Million-Year-Old S...

Artistic representations of ancient humans often show large men with bulging muscles – but our ancestors were actually smaller than us, in both height and body mass. Columnist Mich...
by Jeffrey C. Schank, Matt L. Miller The ultimatum game (UG) is widely used to study mutually beneficial exchanges, fairness, and prosocial behavior across different societies. Ho...
Researchers have identified a previously unknown fossil ape from Egypt that could alter long-held ideas about the origins of modern apes. The evolutionary story of apes has long co...
In evolution, mutations that increase fitness can be thought of as moving uphill, whereas mutations that decrease fitness can be thought of as moving downhill. Source
A new study utilizes molecular genetic timelines to validate the "brain lag" hypothesis, proving that primate body growth preceded brain expansion. The analysis expands the theory...
