New research challenges long-standing assumptions about human evolution, revealing that natural selection has been more ...

Species either adapt or die. This is the basis for extinction, and why many animals eventually succumb to various factors that threaten their existence. In some rare cases, however, a species responds ...

DNA switches that predate humans and Neanderthals still influence how people speak today, offering new clues about language ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

Scientists have identified how specific genetic changes function in cells to influence disease risk and other human health traits. By probing regions of DNA previously linked to disease, the work has ...

Scientists have discovered that a protein once thought to simply help load a factor necessary for the copying of DNA, actually plays a key role in ensuring fast and reliable replication—an insight ...
