Vast genetic changes can occur in hatchery-raised fish in as little as one generation, according to the latest study from Oregon State University. This poses a significant threat to wild populations that come in contact with their genetically unique relatives.
Female cuckoos are known for laying their eggs in the nests of other birds. A new study from the Norwegian University of Science and Technology reveals how females are able to lay a variety of different egg colors to match those of their hosts, thus ensuring they are not kicked out before they are full grown.
Previous studies suggest older parents give birth to offspring that, on average, live shorter lives. In a recent study of European shorebirds, researchers believe they have shed some new light on the matter.
Male wild guinea pigs pass down their ability to adjust to environmental changes to their sons. Researchers suggest future generations could benefit from this "epigenetic information" as climate change causes global temperatures to rise.
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.
Members of both animal and human social groups work together to hunt, forage and fight under the guidance of leader. A recent study took a closer look at the nature of leadership to better understand how human and non-human leaders promote cooperative actions.
Scientists have discovered a new breast cancer gene, providing insight into the most common cancer among American women, according to new research.
