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

Why do humans have larger penises than other primates? New research tests attraction, rivalry, and sexual selection for ...

Shane Campbell-Staton is professor of evolutionary biology at Princeton University. He's also the host of the PBS show, Human Footprint, where he travels the world exploring how our species is ...

Artificial intelligence allows tracing the evolution of genetic control elements in the developing mammalian cerebellum. An international research team led by biologists from Heidelberg University as ...

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 ...

Harvard Faculty of Arts and Sciences has officially voted to change the name of the Human Evolutionary Biology concentration during a meeting on April 1. Effective as of July 1, 2025 — when the ...

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 ...

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 ...

Human penis size indicates male attractiveness and fighting ability, with a larger size more attractive to women and more ...

In this computer simulation of a self-replicating structure, the pink square represents the signal to degrade the connection between the "parent" structure (left) and its "offspring" (right). This ...
