Although colonies of Florida carpenter ants have designated roles, researchers managed to turn foraging ants into scouts with the use of epigenetic drugs. This suggests social behavior is not necessarily based on an individual's genetics.
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.
Most wild horses have lost their unique wild Dun coats that are characterized by pale hair and zebra-like dark stripes. In a recent study, researchers investigate the genetics behind this unique skin pigmentation and why horses have evolved differently.
Japanese macaques are exposed to various stressful situations in the wild, including rank fights and mating competitions. Researchers recently took a closer look at how genetics ultimately control the release of stress hormones in these animals.
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.
Following the 1964 Alaskan earthquake, marine-dwelling three-spine stickleback fish had to rapidly evolve to live in freshwater ponds. This sheds light on how other species may be impacted by climate change.
The evolution of modern birds was largely shaped by Earth's changing geography and climate. In a recent study, researchers discovered the birds we know today share a common ancestor that arose in South America 90 million years ago.
How did skates and rays develop their unique wing-like fins? Researchers from the University of Chicago recently revealed the animals altered their body structure to live on the ocean floor, and to do so they relied on repurposed genes.
Black swans' wariness is partly determined by their genes, researchers reveal in a new study. This could have important implications for releasing captive-bred birds into the wild.
Scientists recently bred the first litter of pigs with a genetic resistance to a deadly virus known as Porcine Reproductive and Respiratory Syndrome (PRRS).
Cheetahs migrated to Africa from North America 100,000 years ago during the last Ice Age. Following their "big move," populations dwindled and incestuous breeding increased. This troubled linage has had a lasting impact on modern Cheetahs, many of which have difficulty reproducing due to a gene mutation that affects sperm development.
Using an ear mite treatment commonly used to kills those found in cats and dogs, researchers from the University of California Davis have developed a way to reduce the presence of tumors in the ears of endangered foxes living on California's Santa Catalina Island.
While there has been much debate regarding how cats first made their way to Australia, a new study has confirmed that the invasive felines arrived with European settlers in the 19th century.
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.
