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.

Officials in Britain and South Africa claim new variants are more easily transmitted. There’s a lot more to the story, scientists say.
Some tree crickets amplify their calls with leaves, giving them an opportunity to mate that they otherwise might miss.
In Simon Baron-Cohen’s “The Pattern Seekers,” the psychologist posits that the systematizing part of our brain, so pronounced in people with autism, might be what makes us unique.
While people deliberately breed plants, a team of researchers say humans have inadvertently prompted this one to develop camouflage.
A surprise clutch of eggs has solved a century-old leaf insect mystery.
The coronavirus is not a shape shifter like the flu virus, but it could become vaccine resistant over time. That prompts researchers to urge vigilance.
The 86-year-old primatologist says it takes more than having opposable thumbs to save our planet.
The lizards have complicated a rule of thumb that in evolution, once you lose a body part, you don’t regain it.
While later dinosaurs in this lineage were giant herbivores with tiny brains, this small species packed a lot more power in its skull.
Just about any other living thing would be liquefied at the forces this insect can withstand.
