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" ...

Findings suggest that new genes can form by repurposing fragments of ancestral genes while incorporating entirely new coding regions (the protein-coding parts of the DNA). This innovative concept ...

The study outlines a new scenario for understanding how genome regulation and chromatin organization influence the evolution of animal body plans. The conservation of genome regulatory elements over ...

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.
