Human ingenuity must keep up with the coronavirus.
A team of biologists and mathematicians studied hours of video to learn how insects take shape in the egg. The secret is geometry.
Evolutionary theories said giraffes developed their height to get to better eats, but ancestors may have gained the advantage through head-butting battles.
Can economics make sense of heroism?
A meme about the transitional fossil Tiktaalik argues that although we did emerge from the sea, we aren’t doing just fine.
Techniques from computer science may help explain the tendency in biology for structures to repeat themselves.
The toxin that makes cane toads so poisonous is causing them to eat their young, but only in Australia, where they became an out-of-control pest.
The specimen shows that modern tuataras found in New Zealand are little changed from ancestors that lived 190 million years.
A team of researchers say that rather than occupying their own branch in the history of life on Earth, horseshoe crabs are in the same group as spiders and scorpions.
Researchers worked out which receptors in your nose detect particular scent molecules, and found evidence of evolutionary change in some of these genes.
Thirteen of Omicron’s mutations should have hurt the variant’s chances of survival. Instead, they worked together to make it thrive.
A Harvard professor for 46 years, he was an expert on insects and explored how natural selection and other forces could influence animal behavior. He then applied his research to humans.
New research published in the journal Nature suggests that the prints, discovered in Tanzania in 1976, were left by an unidentified hominin, or early human ancestor, more than 3.6 million years ago.
The debate isn’t just about creationism and stem cells anymore.
Researchers unlocked some of the genetic secrets that helped the colorful fruit evolve into so many varieties around the world.
A new study reveals how some mammals evolved nature’s most impressive chompers (which are not always used for chomping).
For the first time, researchers have found a nonhuman animal that seems to have a sense of the beat.
Scientists identified the genes that played a role in many female elephants of Mozambique’s Gorongosa National Park being born without tusks.
Viral evolution is a long game. Here’s where scientists think we could be headed.
Many creatures use mimicry to hide from predators. This one also uses it to lure in prey.
Scientists designed a virtual reality experiment to understand just how tricky rattlesnakes can be.
That this perennial wildflower digests trapped insects suggests that other plants’ appetites for animals may be overlooked.
Sydney’s clever and adaptable sulfur-crested cockatoos learn how to pry open garbage bins by watching one another.
A laborer discovered the fossil and hid it in a well for 85 years. Scientists say it could help sort out the human family tree and how our species emerged.
While on a college field trip to collect beetles, he found salamanders. He became an authority and later grew alarmed by the disappearance of many amphibians.
Elaborate feather microstructures allow male tanagers to enhance their colors, making them seem as if they are higher quality mates.
New generations of a critically endangered species of songbird are failing to learn the tunes they need for courtship. It could lead to extinction.
In “A Zoologist’s Guide to the Galaxy,” Arik Kershenbaum uses his knowledge of the various species here on Earth to speculate about what might exist out there.
A study shows that pretending to be immobile — sometimes for an hour or more — helps larvae of insects called antlions outlast hungry predators.
Eyeless roundworms may have hacked other cellular warning systems to give themselves a form of color vision.
Scientists don’t know yet whether the mutation makes the variants more contagious, but they are concerned that it might.
Researchers grew clusters of brain cells in the lab with a gene carried by our ancient ancestors.
We can thank our heads and shoulders — and not just our knees and toes — that we evolved to run as well as we do.
New studies underscore how coronaviruses frequently mix their genetic components — which could contribute to the rise of dangerous variants.
The father of evolutionary theory held women to be intellectually inferior to men, with one notable exception. Michael Sims explains.
On some Japanese islands where lizards live, the ones that fear predators have higher body temperatures that help them run faster.
Researchers have produced the most comprehensive platypus genome yet, as well as that of another monotreme, an echidna.
