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 ...

In tropical climates, lizards are everywhere. It can be a bit wild to see, and they come in all shapes and sizes. They seem a tad superfluous in such large varieties leaving one to wonder, what ...

MPN-BP transformation is driven by sequential mutations disrupting genomic stability, with TP53 mutations being strong predictors of progression. TP53 mutations confer a selective growth advantage, ...

Evolution is slow, but with the right experimental set-up—and enough time to spare—you can watch nature do its methodical ...

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

Explore the fascinating ways dog breeds continue to evolve through genetic influences. Coat Length The fluffy Afghan Hound ...

When cells divide and chromosomes are replicated for the daughter cells in a select type of cell called the germline, which is happening constantly in living things, sometimes things don’t go ...

Human evolution may no longer be driven primarily by genetics, according to a new theory by researchers at the University of Maine which claims that cultural systems are now shaping the way humans ...

The present theory offers a unified solution to three closely related evolutionary problems. (1) Why does an evolving population explore only a small fraction of the accessible pathways in genotype ...
