UTA researchers set out to determine whether pythons could have adapted to an extreme Florida freeze event in 2010. They generated data for dozens of samples before and after the freeze event. By scanning regions of the Burmese python genome, they identified parts of the genome that changed significantly between the two time periods, providing clear evidence of evolution occurring over a very short time scale in this population.
Michigan State University researchers have improved an introductory biology class to make it more accessible for students not majoring in life sciences. The new course, 'Integrative Biology: From DNA to Populations,' features Avida-ED, a digital evolution software program that allows populations of digital organisms, aka Avidians, to undergo actual, not simulated, evolutionary change.
People who have better spatial memory are also better at identifying odors, according to a study published this week in Nature Communications. The study builds on a recent theory that the main reason that a sense of smell evolved was to aid in navigation, since most animals rely primarily on smell to find food and avoid predators.
Computational image analysis of behaving cuttlefish reveals principles of control and development of a biological invisibility cloak.
Researchers from the Max Planck Institute for Evolutionary Anthropology and the University of Leipzig presented experienced human raters with digital images of rhesus macaques of different ages and asked them to identify related individuals. They found that although infant rhesus macaque faces are individually distinguishable, only just before they reach puberty can offspring be matched correctly to the faces of their parents.
Scientists at Oregon State University have shed light on the evolutionary history of a soil-borne bacteria that is so dangerous to grazing animals it is kept behind lock-and-key to prevent its spread.
Pioneering research has given a fascinating fresh insight into how animal nervous systems evolved from simple structures to become the complex network transmitting signals between different parts of the body.
Researchers reporting in Current Biology on Oct. 18 have described a remarkable new species of fish that lived in the sea about 150 million years ago in the time of the dinosaurs. The new species of bony fish had teeth like a piranha, which the researchers suggest they used as piranhas do: to bite off chunks of flesh from other fish.
Gene AMY1, which kickstarts digestion of starch in the mouth, is associated with blood glucose levels and digestion of carbohydrates, with implications for understanding human evolutionary biology and the gut microbiome.
Samples of ancient sediments from a lake basin in East Africa have revealed that arid conditions developed in the area around half a million years ago, an environmental change that could have played a major role in human evolution and influenced advances in stone technology, according to an international research team that includes geologists from Georgia State University.
