Scientists have long debated how modern humans evolved. For decades, most researchers agreed that Homo sapiens came from one ancestral group in Africa, dating back 200,000 to 300,000 years. But new ...

A major evolutionary theory says most genetic changes don’t really matter, but new evidence suggests that’s not true. Researchers found that helpful mutations happen surprisingly often. The twist is ...

Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long ...

Imagine if scientists could reach back through time and recover the genetic blueprints of species that vanished thousands of years ago, then use those ancient instructions to rebuild lost traits in ...

As our evolution slows and industrialization and technology accelerates, a growing body of research suggests that human biology is struggling to keep pace. Many of the chronic stress-related health ...

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 ...

A novel iLDS statistic uncovers adaptive gene sweeps in gut bacteria, highlighting evolutionary responses to modern diets and enhancing microbiome studies.
