DNA in a fossil from a young girl has revealed that a mysterious extinct human lineage occupied Asia longer than previously thought, allowing more potential interbreeding with Neanderthals.
Evolution is among the most substantiated concepts in science and is the unifying theory of biological science. Charles Darwin co-originated, with Alfred Russel Wallace, the theory of evolution by natural selection. His masterwork, the 1859 "Origin of Species," offered ample evidence for evolution having occurred, as well as the first strong explanation for its mechanism, natural selection. Modern evolutionary theory incorporates these concepts: species change over time; genetic mutations are responsible for the changes; individuals with beneficial genetic mutations will survive preferentially compared with their competitors, in a process known as natural selection; those successful individuals' more numerous offspring will spread the beneficial genetic constructs throughout the population; when enough genetic changes reproductively isolate a population, that population has become a new species. Here you'll find news and information on evolution and the battle with proponents of so-called creation science.
A new fossil find, named Coronodon havensteini, helps explain the unusual eating habits of the blue whale.
An oddball extinct animal discovered nearly 200 years ago recently confirmed its place on the mammal family tree, thanks to newly discovered DNA evidence.
The oldest known bones of our species, dating back around 300,000 years, have been discovered in a cave in Morocco.
A newly identified, 130-million-year-old marine reptile was enormous, measuring the length of nearly three grand pianos lined up, but it wasn't a top marine predator, a new study finds.
The early ancestors of 100-foot-long blue whales were dolphin-sized, according to new research that explains how they and other whale giants got to be so big.
The graceful whale swims by undulating its wide tail up and down, while the shark swims by moving its tail side to side. Why the difference?
DNA from Neanderthals and a mysterious branch of humanity called Denisovans has been detected in the ancient mud of caves holding no fossilized remains of those individuals.
New research on Indonesian fossils reveals clues to an ancient expansion out of Africa led by human ancestors nicknamed "hobbits."
Scientists have found what they are saying could be the oldest evidence of human activity in North America — the marked bones of a mastodon dating back some 130,000 years.
If scientists were to draw an enormous family tree for all of Earth's animals, the oldest branch would belong to the jellyfish, a new study finds.
A new study assesses the evolutionary dynamics of physically embodied robots — and it suggests that we're mashing the fast-forward button on the impending robotic revolution.
Forget what you know about the birds and the bees: Sometimes you just have to take matters into your own hands.
They can be bulbous, pert, or pointy — but why do some noses look different than others? It could have something to do how humans evolved to live in certain climates, a new study suggests.
