Compared with apes, people's gut bacteria lack diversity, study finds
The microbes living in people's guts are much less diverse than those in humans' closest relatives, the African apes, an apparently long evolutionary trend that appears to be speeding up in more modern societies, ...
Team reveals new findings about insect diversification
Biologists from the University of York have compiled two new datasets on insect evolution, revealing that metamorphosing insects diversify more quickly than other insects and are therefore the biggest contributors to the ...
Scientists show that evolution of complex bioluminescent traits may be predictable
A longstanding question among scientists is whether evolution is predictable. A team of researchers from UC Santa Barbara may have found a preliminary answer. The genetic underpinnings of complex traits in ...
HMS Beagle sketchbooks added to Cambridge Digital Library
Tiny sketchbooks that bring to life one of the most famous voyages in history have been digitised and made available online for the first time.
Testing shows billfish demonstrate bone remodeling without osteocytes
The roots of human altruism
Scientists have long been searching for the factor that determines why humans often behave so selflessly. It was known that humans share this tendency with species of small Latin American primates of the ...
Tiny fish provides giant insight into how organisms adapt to changing environment
An Indiana University-Dartmouth College team has identified genes and regulatory patterns that allow some organisms to alter their body form in response to environmental change.
Of dragonflies and dinosaurs: Researchers map insect origins, evolution
When the dinosaurs ruled the earth, they were already bugged by creatures who had gotten there many millions of years earlier: Dragonflies and damselflies. In fact, says Rutgers University-Newark biologist, ...
Preferences for manly men and feminine women linked to urbanization
(Phys.org) —Preferences for highly masculine men and feminine women may emerge only in highly developed environments, according to new research from Brunel University London and the University of Bristol.
Desires of microscopic shrimp illuminate evolutionary theory
A nighttime light display on a coral reef in the Florida Keys sparked a study that provides novel insight into the factors that drive the evolution of new species.
Research confirms controversial Darwin theory of 'jump dispersal'
More than one hundred and fifty years ago, Charles Darwin hypothesized that species could cross oceans and other vast distances on vegetation rafts, icebergs, or in the case of plant seeds, in the plumage ...
Study of lice DNA shows humans first wore clothes 170,000 years ago
(PhysOrg.com) -- A new University of Florida study following the evolution of lice shows modern humans started wearing clothes about 170,000 years ago, a technology which enabled them to successfully migrate ...
Study shows evolutionary adaptations can be reversed, but rarely
(PhysOrg.com) -- Ever since Charles Darwin proposed his theory of evolution in 1859, scientists have wondered whether evolutionary adaptations can be reversed.
Calculating evolution: Program predicts the development of influenza viruses
For a long time, prognoses forecasting the evolutionary future of organisms were considered mere speculation. Together with researchers from Cambridge and Santa Barbara scientists at the Max Planck Institute ...
