Geologist analyzes earliest shell-covered fossil animals
The fossil remains of some of the first animals with shells, ocean-dwelling creatures that measure a few centimeters in length and date to about 520 million years ago, provide a window on evolution at this ...
Researchers Find Key 'Conductor' of Nature's Synchronicity
(PhysOrg.com) -- Synchronicity in nature is seen in beating hearts, the flashing of fireflies' lights, the ebb and flow of infectious disease—and the simultaneous rise and fall of populations across vast ...
Social or stinky? New study reveals how animal defenses evolve
When people see a skunk, the reaction usually is "Eww," but when they see a group of meerkats peering around, they often think "Aww."
Squabbling meerkats make better decisions
Conflicting interests within a group can lead to better collective decisions – if you're a social animal such as a meerkat – according to new research by a team of biologists and political scientists ...
Touch screens help monkeys relax
Zoos are great places to study animals. The non-human primates among them get the most attention from researchers. Some of them are trained to interact with computers for psychological research. In a new ...
Researchers examine the social networks of wild giraffes
(Phys.org) —New research from The University of Queensland reinforces the value of network analysis and long-term studies for examining the social systems of wild animals.
Darwin's dilemma resolved: Biologists measure evolution's Big Bang
A new study led by Adelaide researchers has estimated, for the first time, the rates of evolution during the "Cambrian explosion" when most modern animal groups appeared between 540 and 520 million years ...
Dogs' behavior could help to design social robots
Designers of social robots, take note. Bring your dog to the lab next time you test a prototype, and watch how your pet interacts with it. You might just learn a thing or two that could help you fine-tune ...
Salamanders under threat from deadly skin-eating fungus
A new species of fungus that eats amphibians' skin has ravaged the fire salamander population in the Netherlands, bringing it close to regional extinction.
Fish leaders are born, not made, study finds
Leadership is an innate quality, said a fish study Wednesday that predicted trouble in animal social groups, also human ones, when natural roles are reversed.
Why guppies have genital claws
New research from evolutionary biologists at the University of Toronto shows that the male guppy grows claws on its genitals to make it more difficult for unreceptive females to get away during mating.
Male guppies ensure successful mating with genital claws
Some males will go to great lengths to pursue a female and take extreme measures to hold on once they find one that interests them, even if that affection is unrequited. New research from evolutionary biologists ...
