Cuckoos hide from each other using 'cryptic' eggs
Cuckoos aren't the kind of parents you'd want. They never raise their young ones, leaving that job to other birds. They achieve this by laying their eggs in other expectant birds' nests, who treat them as ...
Population density and testes size: More than meets the eye
A team of researchers has discovered that changes in population density can affect the size of animals' testes and therefore impact on reproduction.
Genetically engineered fruit flies could save crops
Releasing genetically engineered fruit flies into the wild could prove to be a cheap, effective and environmentally friendly way of pest control according to scientists at the University of East Anglia and ...
Computer model simulates Neolithic transition from egalitarianism to leadership and despotism
Early dino was turkey-sized, social plant-eater
The forerunner of dinosaurs like three-horned Triceratops was a bird-hipped creature the size of a turkey that lived in herds in South America and liked to munch on ferns, scientists said Wednesday.
New study advances 'DNA revolution,' tells butterflies' evolutionary history
By tracing nearly 3,000 genes to the earliest common ancestor of butterflies and moths, University of Florida scientists have created an extensive "Tree of Lepidoptera" in the first study to use large-scale, next-generation ...
When cooperation counts: Researchers find sperm benefit from grouping together in mice
Everybody knows the shortest distance between two points is a straight line, and now Harvard researchers have evidence that sperm have been taking the familiar axiom to heart.
Evolution in rainforest flies points to climate change survival
Scientists believe some tropical species may be able to evolve and adapt to the effects of climate change.
Ancient genetic material from caries bacterium obtained for the first time
Streptococcus mutans, one of the principal bacteria that cause dental caries, has increased the change in its genetic material over time, possibly coinciding with dietary change linked to the expansion of ...
Genome study indicates peacock eyespots likely developed to impress females
Researchers find red fluorescence in fish is for vision not UV protection
Maternal effect key to fish combating climate change
(Phys.org) —According to research by Western scientists, thermal tolerance in a wild fish population is a key factor in understanding how animal species adapt to climate change.
Research calls for a new diet classification for mammals
The analysis of 139 land mammals' dietary preferences has led researchers to call for a new classification system, as many diets were varied beyond the current understanding of herbivore, carnivore, or omnivore.
Beautiful but a threat: Tropical fish invasion destroys kelp forests
The migration of tropical fish as a result of ocean warming poses a serious threat to the temperate areas they invade, because they overgraze on kelp forests and seagrass meadows, a new study concludes.
