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.
In biology, the study of these very special sperm cells makes it possible to learn more about species such as parasitic worms.
Plants, in their fossil forms, can reveal a great deal about past environments and climates.
Current trends suggest that evangelicalism is out of step with younger Americans. But, a scholar says, evangelicalism has been here before.
Bipedal movement has existed in modern reptiles for much longer than we previously knew.
Many living vertebrates have the ability to detect electric fields, especially in other animals when hunting. But what can the fossil record tell us about the origins of this sensory system?
Little skates that 'walk' across the ocean floor show how fish brains evolved to pave the way for working legs.
Jealousy works in the same old ways – even in the age of online infidelity.
Meet the brawny bug with a concoction so caustic it'll make a toad vomit.
New discoveries are changing archaeologists' ideas about the origins of our own species and our migration out of Africa. This fossil pushes Homo sapiens' African exodus date back by 50,000 years.
