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.
Aliens are highly likely to undergo natural selection, shows new research.
Did we evolve the capacity to produce sublime music simply to get more sex? Or are we driven by higher ideals related to living together in harmony? Maybe it's a bit of both.
Comparing genomes of more than 200,000 people, researchers identified genetic variants that are less common in older people, suggesting natural selection continues to weed out disadvantageous traits.
A group of lizards in Brazil have evolved bigger heads in just 15 years thanks to their new environment.
Many scientists say there's no purpose to life – but a theoretical study suggests there could be.
We don't know much about the origins of most human achievements – scientific and otherwise. Like evolution, does progress occur as random insights are selected for or against?
While there is currently interest interest in artificial intelligence, it offers limited achievements, such as the autonomous car. Tomorrow, machines will learn alone and forge solutions.
In science, the word 'theory' has a very specific meaning that's easy for nonscientists to misunderstand or misconstrue. Here's what a theory must withstand to be accepted by the scientific community.
It's a watery battle of the sexes.
Animals that group together to fight off evolutionary pressure may actually evolve faster.
Scientists of all kinds turn to computer models to investigate questions they can't get at any other way. Here's how models work and why we can trust them.
