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, ...

Wild scarlet monkeyflowers in California survived a historic drought by relying on a rapid evolution, marking the first time the process has been observed in the wild.

It is often assumed that modern humans are no longer evolving. But there is now considerable agreement among scientists that evolution is still affecting our species—and this process is taking place ...

The development of hair was of central importance for the evolution of mammals and, thus, also of humans. However, the evolutionary origin of the genetic program of hair was previously unknown. An ...

In Lake Malawi, hundreds of species of cichlid fish have evolved with astonishing speed, offering scientists a rare opportunity to study how biodiversity arises.

More than 2.3 million ancient genetic switches discovered in plants reveal how key growth controls endured 300 million years ...

From epic poetry to game shows, from Stone Age axes to spaceflight, humans have the most complex cultures of any species on Earth. Since the time of Darwin, scientists have suspected that this culture ...

A new Yale study provides a fuller picture of the genetic changes that shaped the evolution of the human brain, and how the process differed from the evolution of chimpanzees. For the study, published ...

In most developing tissues, signals called morphogens act like lighthouses, guiding nearby cells toward their fate and telling them what to become. Each cell relies on such signals for organized ...

Important, previously unrecognized genetic changes common to all ancient and modern Homo sapiens spread in Africa more than 300,000 years ago, a new study finds. After that, the same investigation ...
