The recent discover that an endangered population of Killer whales living in the Pacific Northwest preferred eating salmon in summer may lead to improved targeted conservation practices.
Skeleton remains excavated from an Anatolia fossil site known as Kumptepe reveal more about the transition humans made from a hunter-gather lifestyle to organized farming 8,000 years ago.
Plants growing in close quarters constantly compete for sunlight, which is essential to their survival. When a plants is shaded from the sun – either by a cloud overhead or competing plant growing next to it – light sensors kick in to trigger growth.
Gender of many reptiles, including crocodilians and turtles, is largely determined by the temperature in which eggs incubate. When taking a closer look at the molecular mechanisms behind this phenomena known as temperature-dependent sex determination, researchers discovered a thermosentive protein inside the egg plays a key role.
Utah's Henry Mountains is home to a viable population of genetically pure, disease-free American bison. Researchers say this could open new doors for improved conservation of these animals, which were recently named the U.S. National Mammal.
Not much is known about fishing snakes; however, a recent discovery of three new species may help scientists shed some light on the already elusive creatures.
Six new clawed frog species were recently found in Central and West Africa. These amphibians are particularly unique, in that they inherit all of their mother's and fathers' genes instead of half from each. Researchers continue to search for the "lost ancestor" that gave rise to this genetically diverse species.
A new study revealed face mites – microscopic animals that live on our faces and in our hair – evolved along side humans. Moreover, people from different parts of the world host different mite lineages that follow families through generations.
Even though Lonesome George -- the last member of the Pinta Island Galapagos Tortoises -- died in 2012, scientists may be able to revive his species with the genetic help of close relatives.
Some prairie voles are monogamous, while others seek out multiple mates. In a recent study, researchers from the University of Texas at Austin reveal sexual behavior is largely controlled by genetic differences in the rodents' brains, suggesting natural selection has allowed for both characteristics to co-exist.
For many species, including humans, sex is determined by sex chromosomes. However, this is not the case for ants, wasps and bees. A recent study sheds light on the evolution of sex determination in ants and how inbreeding can lead to sterile males.
Notre Dame researchers recently revealed the DNA of trapped insect prey can be collected from a black widow spider's nest up to 88 days later. This finding has significant implications for conservation management.
After sequencing the genome of nearly indestructible water bears (segmented micro-animals), researchers discovered they steal 17.5 percent of their genetic information from other species.
The corn snake's genome has been sequenced for the first time, and reveals important information regarding the gene mutation responsible for albinism.
