Latest Natural selection Stories
Introducing a new approach that combines evolutionary and engineering analyses to identify the targets of natural selection
In a blind fish that dwells in deep, dark Mexican caves, scientists have found evidence for a long-debated mechanism of evolutionary change that is distinct from natural selection of spontaneously arising mutations
What is more useful? Having a superpower, or the ability to develop a superpower? Evolution, of course, picks the latter.
Depending on the environment in which the worm grows, the larva of the roundworm Pristionchus pacificus develops into either a wide-mouthed predator or a narrow-mouthed bacteria eater.
A new study of butterflies found that it’s genetically easier to spin off into a new species than it may have once been thought, even if the two species remain close and interbreed with one another.
Saving energy is important for humans and animals alike when resources are limited.
A new study from the National Institute for Mathematical and Biological Synthesis finds that a female's mating decisions are largely based on traits that reflect fitness or those that help males perform well under the local ecological conditions.
Environment is not the only factor in shaping regulatory patterns — and it might not even be the primary factor, according to a new Rice University study that looks at how cells’ protein networks relate to a bacteria’s genome.
In many places around the world, people are living longer and are having fewer children. But that's not all. A study of people living in rural Gambia shows that this modern-day "demographic transition" may lead women to be taller and slimmer, too.
Researchers found similar or identical genetic mutations can emerge in separate populations of E. coli evolving in different environments for over 1000 generations, leading the team to conclude that evolution can be fairly predictable.
