The conservation of genome regulatory elements over long periods of evolution is not limited to vertebrates, as previously ...

The history and diversity of life on earth are testimony to evolutionary processes that extend back to the dawn of time. The agent of change and diversification is natural selection acting over long ...

A research team has clarified a mechanism of how retrotransposons, genetic elements that can 'jump around' chromosomes and are known drivers of evolution, preferentially insert in the centromere. A ...

The sequencing of the genomes of a spider from the mainland (Dysdera catalonica, left) and one from the Canary Islands (Dysdera tilosensis, right) opens a new perspective for understanding how genome ...

The cellular biology of reproduction is often depicted as an epic journey, in which millions of intrepid sperm fight to be the first to claim the ultimate prize: the chance to fertilize the egg, which ...

Researchers have discovered a previously unknown mechanism by which bacteria share their genetic material through virus parasites. The insights could help scientists to better understand how bacteria ...

Biologists are closing in on a puzzle that seems to turn classic evolutionary logic inside out, yet may be so common that it ...
