The relatively swift adaptability of tiny, acorn-dwelling ants to warmer environments could help scientists predict how other species might evolve in the crucible of global climate change.
That's a big-picture conclusion from research into the some of the world's smallest creatures, according to evolutionary biologists at Case Western Reserve University.
More specifically, the scientists are comparing the...
Scientists have revisited -- and confirmed -- one of the most famous textbook examples of evolution in action.
They showed that differences in the survival of pale and dark forms of the peppered moth (Biston betularia) are explained by how well camouflaged the moths are to birds in clean and polluted woodland.
"Industrial melanism" -- the prevalence...
Flowering plants are well known for their special relationship to the insects and other animals that serve as their pollinators. But, before the rise of angiosperms, another group of unusual evergreen gymnosperms, known as cycads, may have been the first insect-pollinated plants. Now, researchers reporting in the journal Current Biology on August 16 have uncovered...
Certain female mosquitoes quickly evolve more selective mating behavior when faced with existential threats from other invasive mosquito species, with concurrent changes to certain genetic regions, according to new research from North Carolina State University. The findings shed light on the genetics behind insect mating behavior and could have implications for controlling mosquito pests that...
Americans' views of possible uses of genetic engineering in animals vary depending on the mechanism and intended purpose of the technology, particularly the extent to which it would bring health benefits to humans, according to a new study released today by Pew Research Center.
Presented with five different scenarios of animal genetic engineering that are currently...
Researchers have found declines in the number and diversity of bird populations at nine sites surveyed in northern New Mexico, where eight species vanished over time while others had considerably dropped.
"These birds are not using these habitats anymore," said Los Alamos National Laboratory scientist Jeanne Fair, lead author of the study published recently in the...
