"Size matters" sounds like a tabloid cliché, but for evolutionary biologists the size of the human penis is truly a puzzle.

Among primates, the human penis is an evolutionary outlier. Controlling for body size, humans have greater girth and generally longer penises than chimpanzees, gorillas, or orangutans. Unlike our ...

Amphioxus, as a basal chordate, offers an insightful window into the evolutionary origins of vertebrate development. Its embryogenesis, characterised by the formation of a notochord, neural tube and ...

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 ...

An international collaboration between four scientists from Mainz, Valencia, Madrid, and Zurich has published new research in the Proceedings of the National Academy of Sciences, shedding light on the ...

A new study by researchers at the Max Planck Institute for Evolutionary Biology (MPI-EB) sheds fresh light on one of the most debated concepts in biology: evolvability. The work provides the first ...
