Latest Evolutionary biology Stories
In a twist on "survival of the fittest," researchers have discovered that evolution is driven not by a single beneficial mutation but rather by a group of mutations, including ones called "genetic hitchhikers" that are simply along for the ride.
If you could hit the reset button on evolution and start over, would essentially the same species appear? Yes, according to a study of Caribbean lizards by researchers at the University of California, Davis, Harvard University and the University of Massachusetts.
Australia’s Office of Chief Scientists released a report on Friday that claims the misuse and overuse of antibiotics could soon send the world back to a nineteenth century era where typical diseases and infections could pose a serious threat.
Mammals are able to "choose" the sex of their offspring in order to beat the odds and produce extra grandchildren, according to a study published in the journal PLoS ONE.
David Wallinga from Keep Antibiotcs Working: the Campaign to End Antibiotic Overuse in Animal Agriculture, believes that physicians and policymakers have "overlooked the critical role played by the ongoing overuse of antibiotics in livestock and poultry."
New research from two biologists at the University of Arizona and Yale suggests that evolution is not an option for species looking to cope with rising global temperatures.
A new study has shed light on the potential of birds to survive in the face of climate change.
Some people possess a small number of cells in their bodies that are not genetically their own; this condition is known as microchimerism.
The death of individual species is not the only concern for biologists worried about groups of animals, such as frogs or the "big cats," going extinct.
Slipping bacteria some silver could give old antibiotics new life.
John Harold Ostrom (February 18, 1928 – July 16, 2005) was an American Paleontologist who was greatly influential in the revival of scientific research on Dinosaurs. He is best known for demonstrating that Dinosaurs were less like contemporary reptiles but more closely related to large, flightless birds like the ostrich – a theory that holds its ground in the paleontological community to this day. John Ostrom was born and raised in Schenectady, New York. His father was a physician, and...
Paleontology or Palaeontology is the scientific study of prehistoric life, including the study of fossils to determine the organisms evolution and interactions with each other and their environments. Paleontological observations have been documented as far back as 5th century BC. The science became established in the 18th century as a result of Georges Cuvier’s work on comparative anatomy, and it developed quickly within the 19th century. The term itself comes from Greek palaios, meaning...
