The purpose of sex may seem obvious, but it has perplexed and intrigued a variety of great minds for millennia.
New research models how the Homo floresiensis species could have evolved its small size remarkably quickly while living on an isolated island.
In science, we look at the evidence and try to find the theory that best explains it. And that's what happened when it came to figuring out evolution.
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.
How and why animals develop as male or female is far more complex than we ever imagined.
Modern science clashes with the idea that the rise of Homo Sapiens was a fluke.
One reason for the likes of the anti-vaxxers movement is a misplaced faith in Mother Nature.
Ever heard of lexical selection? Every time you open your mouth you change the way future generations will talk.
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.
Citizen science game offered clues to why shore crabs get greener as they grow.
Why are humans the only animals with chins?
Natural selection isn't the only factor deciding human evolution.
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.
New research shows the Bajau Laut people of Southeast Asia have evolved bigger spleens to store more oxygen-rich blood.
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.
New research uses pathology in dinosaur bones to look at predator-prey interactions in the fossil record.
