New research shows that ground-dwelling birds were more likely to survive the mass extinction at the end of the Cretaceous period.
No mother wants their baby to develop jaundice, but it turns out that they should probably be grateful.
We don't have evidence that can point us to the exact purpose of yawning. But there are several theories.
New research shows green-blooded skinks have evolved multiple times, which could help lead to explanation as to why.
Why do some people reject scientifically accepted ideas? A psychotherapist points to black-and-white thinking as part of the explanation.
Most of our genes descend directly from the last common ancestor of animals.
A theory is not meant to be a final statement of how things are, but just the latest stage of ongoing research and new discoveries.
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.
As a post-antibiotic future beckons, how can humanity protect itself against the proliferation of superbugs? Research suggests 'drug sanctuaries' in hospitals could be a promising solution.
New research shows the Bajau Laut people of Southeast Asia have evolved bigger spleens to store more oxygen-rich blood.
Northern seals use strong claws to tear apart large prey and this gives us clues about how the earliest seals likely behaved when they first began feeding in water.
Rather than trying to out-compete each other, flowers may work together to attract bees en masse. It's the sort of approach that is effective in the world of advertising too.
Having movable eyebrows – and evolving beyond the Neanderthal ridge – may have played a crucial role in early human survival.
Dogs don't follow the rules on larger animals living longer. A 70kg Great Dane is lucky to reach seven years, but a 4kg Chihuahua can live for 10 years or more.
DNA studies reveal that African elephants belong to a very successful and widespread family.
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.
Humans have long been trying differentiate themselves from the rest of the biological world. Is it because we're superior, or just insecure?
The genes in our cells' mitochondria are passed on in a different way than the vast majority of our DNA. New studies shed light on how the unique process isn't derailed by mutations.
The short answer is no. An individual of one species cannot, during its lifetime, turn into another species. But your question helps us think about life, evolution and what it means to be human.
