When explaining human origins, a staggering 42% of all Americans still ascribe to a creationist interpretation—despite the fact that there’s plenty of evidence to support the theory of natural selection. Here are some of the most potent scientific discoveries that prove Darwin was right.
By simulating a mass extinction on a population of virtual robots, researchers have shown that these cataclysmic events are an important contributor to an organism’s ability to evolve, a finding that has implications to evolutionary biology, the business sector—and even artificial intelligence.
The discovery of Pappochelys, a Triassic-era reptile with a set of emerging turtle-like features, is helping scientists fill in an important evolutionary gap.
Since the time of Darwin, evolutionary biologists have wondered why the lifespans of different species vary so significantly. A new model now suggests that the life expectancy of any given species is a function of evolutionary pressures — a conclusion that hints at the potential for powerful anti-aging interventions…
Esteemed evolutionary biologist E. O. Wilson believes the only way we can avoid a catastrophic mass extinction is to set aside half of the planet in permanently protected areas for the 10 million other species who live on Earth. Wilson calls the concept "Half Earth" — and he says its not as outlandish as it might…
For decades, most evolutionary biologists based their understanding of female mating choice on a paper that turned out to be incorrect. The idea that females (including human ones) always choose the single "best" mate, rather than choosing promiscuity? Wrong.
Evolutionary biologists like to say that mutations are random but that selection is not; species are crafted by their environments. But if this is the case, why is it so hard to predict evolution? A recent genetic analysis of stick insects provides an important clue.
Dinosaurs took on many different shapes and sizes, but paleontologists are learning their success had nothing to do with their iconically massive bodies. If anything, their evolutionary success would appear to have come from their longstanding ability to keep shrinking. Just ask the birds.
We humans are a smart bunch, but we really suck when it comes to understanding and handling excessively large numbers. Here's why we're so bad at it — and what you can do to make sense of concepts and figures that are unreasonably huge.
All whales and dolphins are descended from terrestrial mammals, ancient creatures that were very similar to the modern hippopotamus. Now, a fascinating new genetics study shows the incredible evolutionary changes these animals had to experience to become the perfectly adapted marine animals we see today.
In a remarkable experiment that's been going on for nearly a quarter century, biologists have shown that lab-grown bacteria — even in a stable, unchanging world — will continue to evolve in a way that makes it increasingly good at reproducing.
Take a look at the battle unfolding in this remarkable image. It shows the sperm from two related fruit fly species competing inside a reproductive tract. It’s an evolutionary struggle that, as scientists are now learning, often leads to the introduction of entirely new species.
Following the publication of Darwin’s On the Origin of Species in 1860, many political theorists and opportunistic politicians applied his findings to human society. In the 20th century, these ideas were put into practice — and it nearly destroyed us. Here’s why Social Darwinism was one of the worst ideas ever.
Some prey animals, like rabbits and deer, feature flashy white tails that are prominently displayed when they're been chased down by predators. But why in the world would an animal want to draw more attention to itself in such a precarious situation? We now have the answer.
Elaine Morgan, author of the highly influential The Descent of Woman, has died at the age of 92 from a stroke. She will be remembered for challenging male-centric theories of human evolution, and for promoting the idea that early humans, for a short time, began adapting to aquatic life.
For the past several decades, scientists have been fascinated by the "social brain theory" — the idea that certain animals evolved big, powerful brains to cope with the complexities of social life. A new computer simulation has now shown that this assertion is likely correct.
A new theory proposed by two computer scientists suggests that animals can still experience significant evolutionary changes over time, even in the absence of selectional pressures.
As a group, primates aren't really known for their ability to create vocalizations, or sophisticated or complex sounds with their mouths. Yes, we humans have shown some talent in that area — what with the whole development of language and all that — but most apes and monkeys are unable to generate anything but the…
