Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe. Using advanced analysis based ...

Human evolution’s biggest mystery, which emerged 15 years ago from a 60,000-year-old pinkie finger bone, finally started to ...

The human genome is made up of 23 pairs of chromosomes, the biological blueprints that make humans … well, human. But it turns out that some of our DNA — about 8% — are the remnants of ancient viruses ...

A breakthrough in human evolutionary research has finally revealed the place where Homo sapiens and Neanderthals first crossed paths. The discovery places the two ancient human species not in the ...

Biology and culture in human evolution -- Heredity -- Environmentalist thesis and hereditarian antithesis -- Equal but dissimilar -- Heredity of health and disease -- Natural selection and survival of ...

A groundbreaking international study changes the view that exposure to the toxic metal lead is largely a post-industrial phenomenon. The research reveals that our human ancestors were periodically ...

Four lifelike reconstructions of prehistoric humans have been unveiled — including a model of a species often dubbed "the hobbit," which, as an adult, was about the same height as a modern 4-year-old.

Researchers discovered that autism’s prevalence may be linked to human brain evolution. Specific neurons in the outer brain evolved rapidly, and autism-linked genes changed under natural selection.

Throughout most of human history, evolution progressed slowly. Small genetic changes took thousands of years to permeate populations. Natural selection was intentional, reactive, and gradual. However, ...

When scientists today work to decode the human genome, they use high-tech methods to view the microscopic chromosomes and even pluck individual genes out of a cell. But in Darwin's time, it was ...
