The human body is full of evolutionary compromises. The loss of the tail may be one of the clearest examples of how change ...

In the spring, ants are once again hard at work. Beyond their everyday presence, ants are also key model organisms in cutting ...

For decades, many evolutionary biologists argued that natural selection acts primarily on individuals. In other words, that organisms are rewarded or penalized one at a time, and that the idea of ...

The work demonstrates the power of ancient DNA to illuminate human biology and medicine in addition to history. A massive ...

Evolutionary biology explores how living systems change over time through variation, inheritance and differential success. At its heart lies the concept of descent with modification: populations ...

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 ...

Mathematical model: The study shows that multicellularity can evolve without direct benefits over unicellular ancestors. In ...

A new paper in Molecular Biology and Evolution, finds that changes in animal development induced by climate shock persist ...

Study finds that the mass extinction caused by an asteroid about 66 million years ago led to critical changes in bird genomes that ultimately sparked the incredibly diversity living birds. Shortly ...

A common element in “Star Trek” and other science fiction is their depiction of humanoid alien species. If life exists ...

Evolutionary developmental biology, or evo‐devo, investigates how evolution shapes developmental processes to generate the diversity of life. It synthesises comparative embryology, genetics and ...
