The study blends math, statistics and biology to show that this long-held hyperbolic pattern is an anomaly because it doesn't account for the fact that all species on earth are defined as much by ...

The new evolutionary study found two main reasons for the primate anomaly: to attract mates and to threaten rivals.

Why does natural selection appear to happen slowly on long timescales and quickly on short ones? A multigenerational study of four lizard species addresses biology’s “paradox of stasis.” James Stroud ...

Evolution is a complicated thing. Much of modern evolutionary biology seeks to reconcile the seeming randomness of the forces behind the process — how mutations occur, for example — with the ...

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 ...

A newly proposed model could rewrite our understanding of life’s history on Earth.
