What drives the emergence and disappearance of species? By modeling the fundamental processes of evolution and ecology on geographical scales, new research spotlights topography and climatic shifts.
Vocal deception may have played a key role in our progression from primitive nonverbal noises to complex, controlled speech.
New research on roaring shows that women underestimate their own strength.
New research shows green-blooded skinks have evolved multiple times, which could help lead to explanation as to why.
Questionable research practices are not fraud, and they're not cause for panic. But they do give us some hints about how we can make science more robust.
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.
More and more evidence shows evolution isn't as random as often thought.
Your voice can affect how attractive, fertile and faithful people think you are.
New research suggests life on Earth became more diverse because of a change in biology related to stem cells, not just rising oxygen levels.
Male Birds of Paradise have patches of super-black plumage that absorb 99.95 percent of light. New research identified their feathers' microscopic structures that make them look so very dark.
An ancient sexual conflict over mitochondrial inheritance may be responsible for the evolution of the two sexes as we know them.
Evolutionary biologists ask very similar questions about species to those asked by linguists about languages.
Ancient whales were neither gentle, nor giants: they were smaller than those of today and judging from their teeth, a lot meaner.
A stable environment that teaches men to be men and women to be women could be helping to enforce gender across generations.
Scientists have reconstructed the common ancestor of everything from rose bushes to oak trees, ivy or wheat.
A group of lizards in Brazil have evolved bigger heads in just 15 years thanks to their new environment.
Taking the placenta as a case study, researchers are able to piece together how new organs evolve, by repurposing old tissues and using them to do new jobs.
Anthropologists gather clues about how our ancient ancestors lived from their teeth. What will future anthropologists make of us based on the fossilized pearly whites we'll leave behind?
A new study suggests women who undergo FGM in societies where it is prevalent have more surviving children – but the evidence isn't strong enough.
Some fish build sandcastles to attract a mate but others just use sneaky tactics.
