Scientists have developed a theoretical model that uncovers the dual role of polyploidy -- organisms carrying extra genome copies -- in evolution. Their findings reveal that polyploidy can stabilize ...

In 1859, Darwin imagined evolution as a slow, gradual progress, with species accumulating small changes over time. But even he was surprised to find the fossil record offered no missing links: the ...

A joint research group team led by Sayuri Tsukahara and Tetsuji Kakutani of the University of Tokyo has clarified a mechanism of how retrotransposons, genetic elements that can "jump around" ...

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 ...

Evolution is the basis of biological diversity, driven by mechanisms that allow organisms to adapt and survive. One such mechanism is polyploidy, where organisms carry extra copies of their genomes.

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 ...
