A unique study of the white-throated sparrow has identified a biological pathway connecting variation in the birds’ aggression and parenting behaviors in the wild to variation in their genome.
Scientists have discovered a mutation with a built-in dilemma for dairy cattle breeders.
New research puts together the final pieces in a puzzle 200 years in the making – determining the molecular evolution in the genes that separate male honey bees from female ones.
Waterfowl such as ducks, geese and swans belong to the order Anseriformes. Game birds such as pheasants, partridges, hens and turkeys are known as the order Galliformes. The birds belonging to both of these orders are recognized not only for their meat, but also for their elegant display of their plumage.
A new study from researchers at the University of Pennsylvania has found a genetic mutation making certain people more sensitive to the taste of a bitter compound could have been beneficial for certain human populations in Africa, resulting in the mutation being passed on from generation to generation.
University of Cambridge New research shows that cuckoos have striped or "barred" feathers that resemble local birds of prey, such as sparrowhawks, that may be used to frighten birds into briefly fleeing their nest in order to lay their parasitic eggs. By using the latest digital image analysis techniques, and accounting for "bird vision" - by converting images to the spectral sensitivity of birds - researchers have been able to show for the first time that the barred patterns on a...
According to a new study published in Psychological Science, some people are genetically predisposed to have a darker perspective.
A specific gene variant is more frequent among elite athletes in power sports, reports a study in the October issue of The Journal of Strength and Conditioning Research, official research journal of the National Strength and Conditioning Association (NSCA).
Human migrations—from the prehistoric epoch to the present day—have extended cultures across the globe.
By studying rapidly evolving bacteria as they diversify and compete under varying environmental conditions, researchers have shown that temporal niches are important to maintaining biodiversity in natural systems.
The Grove Snail (Cepaea nemoralis) is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk. It is one of the most common species of land snail within Europe and has been introduced to North America. C. nemoralis is the type species regarding the genus Cepaea. It is used as a model organism in citizen science projects. This snail species is among the largest due to its polymorphism and bright colors. The color of the shell is very variable, reddish, yellow,...
