Early human evolution may have been more complex than scientists previously thought, with modern humans evolving from two ...

also known as the process of evolution. Genetic variation is usually expressed as a relative frequency, which means a proportion of the total population under study. In other words, a relative ...

Scientists have uncovered evidence that modern humans emerged from two long-separated ancestral groups, not just one. This ...

EvolGenius is a two-locus population genetics simulation written for use in undergraduate courses. Often, we use simulations without really thinking about how they recreate a process. But ...

Scientists discovered humans descended from two ancient populations, not one. These groups split 1.5 million years ago.

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.

New research has shown that modern humans descend from not one but two separate ancient human ancestral lineages.

Research that combined archaeology, history and ecology provides a nuanced understanding of the past that could help ...
