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 ...

For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and ...

Researchers from Heinrich Heine University Düsseldorf (HHU) and Kiel University (CAU) led by Professor Sebastian Fraune use the example of the sea anemone Nematostella vectensis to investigate the ...

The history of the Earth has been one of physical extremes—extreme atmospheric conditions, extreme chemical environments, and extreme temperatures. There was a time when the Earth was so hot all the ...

Microbes are present in most environments on Earth, from the depths of the ocean to the air we breathe, and even live inside other organisms where they play an important biological role. They are ...

Evolution is the basis of biological diversity, driven by mechanisms that allow organisms to adapt and survive. One such ...
