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 ...

Life in the wild is never constant; animals adapt quickly if they are to survive. Climate change, the reduction of habitats, and human interference ar.

Charles Darwin's theory of evolution generated scientific debate and discussion not only in Darwin's own time, but for decades afterward. In the latter part of the nineteenth century and the until the ...

Centralized migration accelerates adaptation and drives parallel evolution, emphasizing the key influence of spatial organization on evolutionary dynamics across systems from pathogen transmission to ...

At some point in the deep past, humans may have come frighteningly close to disappearing altogether. Here’s what we know, ...

Genetic research does not always produce tidy answers. Sometimes it reveals traces that raise more questions than they settle ...

Understanding biological relationships is often critical when studying animal populations. Researchers have now developed a transformative approach that identifies stretches of DNA that two ...
