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

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 ...

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 ...

The founder effect is an extreme example of "genetic drift." Genes occurring at a certain frequency in the larger population will occur at a different frequency -- more or less often -- in a ...

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.

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

Instead of relying on just one "standard" genome, it includes a collection of many different genetic versions specific to the Arab population. This helps scientists see the full picture of genetic ...

"This population would later contribute ... they may have been less compatible with the majority genetic background. This hints at a process known as purifying selection, where natural selection ...
