  • Cancer-like metabolism and human brain size evolution

    The size of the human brain increased profoundly during evolution. A certain gene that is only found in humans triggers brain stem cells to form a larger pool of stem cells. As a consequence, more neurons can arise, which paves the way to a bigger brain. This brain size gene is called ARHGAP11B and more

  • Self-restrained genes enable evolutionary novelty

    Changes in the genes that control development can potentially make large contributions to evolution by generating new morphologies in plants and animals. However, because developmental genes frequently influence many different processes, changes to their expression carry a risk of “collateral damage more

  • New insights into the evolution of proteins

    How do bacteria manage to adapt to synthetic environmental toxins and, for example, to even develop strategies for using a pesticide and chemical warfare agent as food within less than 70 years? The evolutionary adaptations underlying such processes have now been studied in detail by an internationa more

Did Comets Kickstart Life on Earth?

That's right. Comets may have helped seed life on Earth. Far out, right? Sarah Everts has the chemical clues that back up this out-of-this-world hypothesis. more

The Race to Crack the Genetic Code

How was the code of DNA cracked? How did it confirm the theory of evolution? And why did life evolve the way it did? Matthew Cobb unravels the tangled story.Matthew Cobb is Professor of Zoology and a senior lecturer in animal behaviour at the University of Manchester. After spending some time re ... more
