If you go by editorial cartoons and T-shirts, you might have the impression that evolution proceeds as an orderly march toward a preordained finish line. But that’s not right at all.
Biologists investigated whether birds that search for multiple mates would evolve ever more elaborate songs to attract them. What they found might have surprised Darwin.
Was Darwin inspired by the tropical wildlife of his travels to discover natural selection? Actually, pigeons, worms and barnacles were far more prominent in his thinking.
An evolutionary biologist visits the remote jungle mountaintop where a little-known naturalist wrote his insightful paper about the mechanisms of evolution that spurred on a rivalrous Charles Darwin.
In the wake of two hurricanes in the Turks and Caicos Islands, researchers document for the first time that catastrophic storms can be agents of natural selection, influencing how species evolve.
In this age of the pseudo-factual, its more important than ever to acquaint ourselves with the foundations of the scientific tradition, such as Darwin’s Origin of Species.
Why was one gene mutation that affects hair, teeth, sweat glands and breasts ubiquitous among ice age Arctic people? New research points to the advantage it provided for ancestors of Native Americans.
A core idea in molecular biology is that one gene codes for one protein. Now biologists have found an example of a gene that yields two forms of a protein – enabling it to evolve new functionality.
