Lizards use bright colors to attract mates but this also makes their camouflage less effective, making them visible to predators, report researchers from the University of Cambridge.
New research shows that blind cave fish (Astyanax mexicanus) evolved to conserve energy. They gave up sight and circadian rhythm to survive solely on their sense of smell and taste.
As a result of domestication, some animals have evolved differently. Scientists believe this is related to their reduced fear of humans and adapting to a tamer lifestyle.
After years of misidentifying Helmeted Woodpeckers, scientists from the University of Kansas have found that the bird has evolved with characteristics of larger competing birds in the Atlantic forest.
Using fossilized teeth, researchers found that humans adapted a grass-based diet 400,000 years earlier than previously thought. This sheds light on how habitat change shaped human evolution.
Barbastelle bats observed in central France have adapted to hunt eared moths more efficiently. Using two different, weak signals, they are able to sneak up on their prey while keeping track of their environment.
Researchers found a protein that helps plants grow in salty soils. This could aid in salt-tolerant crop development.
Antarctic fur seal pups listen for their certain qualities in their mother's vocal signature in order to correctly identify them in dense colonies.
Insect-eating Balkan green lizards have new digestive systems that allow for varied food consumption. Researchers believe this is a result of less rainfall affecting their food supply.
A recent study of almost 13 thousand marine species found that they don't have many options when climate change sets in. They will either have to relocate to other parts of the ocean or face extinction.
While certain stink bugs have always created a problem for soybean farmers, the redbanded sink bug is present in very high numbers and is becoming resistant to common insecticides.
Ants have been found to have the ability to change their diet to contain free radicals, such as hydrogen peroxide, to help fight infectious, and otherwise fatal, diseases. This is similar to humans' use of antibiotics.
Female guppies can avoid male guppy courting by not only increasing their speed, but also by perfecting their swimming technique, say researchers.
Bluebirds are able to increase their songs and lower their pitch to compensate for increasing background noises that otherwise inhibit communication between them and their potential mates.
