Genes may travel from plant to plant to fuel evolution

Evolutionary biologists at the University of Sheffield and Brown University have documented for the first time that plants pass genes from plant to plant to fuel their evolutionary development.



Unlocking one of the great secrets of Earth’s evolution

Settling a debate going back to Darwin



New hypothesis for human evolution, nature

A paleoanthropologist argues that the human-animal connection goes well beyond simple affection and proposes that the interdependency of ancestral humans with other animal species played a crucial and beneficial role in human evolution.



Competition puts the brakes on body evolution

Often mistaken for chameleons or geckos, Anolis lizards fight fiercely for resources, responding to rivals by doing push-ups and puffing out their throat pouches. But anoles also compete in ways that shape their bodies over evolutionary time, says a new study.



Flu's Evolution Strategy Strikes Perfect Balance

Scientists have uncovered the flu's secret formula for effectively evolving within and between host species. The key lies with the flu's unique replication process.



Site of human evolution was scorching

According to scientists, the need to stay cool in that cradle of human evolution may relate, at least in part, to why pre-humans learned to walk upright, lost the fur that covered the bodies of their predecessors and became able to sweat more.



Jumping genes key to evolution

Researchers found extensive variation in these locations among the individuals they studied, further underscoring the role of these errant genes in maintaining genetic diversity.



Did phosphorus trigger complex evolution?

The evolution of complex life forms may have gotten a jump start billions of years ago, when geologic events operating over millions of years caused large quantities of phosphorus to wash into the oceans.



Evolution takes different paths

Biologists long have known that both the appearance of organisms and their inner workings are shaped by evolution. But do the same genetic mechanisms underlie changes in form and function?



The driving force behind evolution

A recent study suggests that species are in a constant race for survival and have to continue to evolve new ways of defending themselves throughout time.



Evolution caught in the act

Scientists have now been able to measure for the first time directly the speed with which new mutations occur in plants.



Study sheds light on evolution

Research shows that human beings are biologically complex because of the way humans evolved to cope with redundancies arising from duplicate genes.



The amazing maze of maize evolution

As one of the most important crops worldwide, understanding exactly how maize has evolved has many practical benefits and may help to improve crop yields.



Scientists watch evolution unfold

A 21-year Michigan State University experiment that distills the essence of evolution in laboratory flasks not only demonstrates natural selection at work, but could lead to biotechnology and medical research advances, researchers said.



Using Synthetic Evolution to Study the Brain

The human brain has evolved over millions of years to become a vast network of billions of neurons and synaptic connections. Understanding it is one of humankind’s greatest pursuits.



Understanding whale and dolphin evolution

When the ancestors of living cetaceans-whales, dolphins and porpoises-first dipped their toes into water, a series of evolutionary changes were sparked that ultimately nestled these swimming mammals into the larger hoofed animal group.



Evolution of the appendix

The lowly appendix, long-regarded as a useless evolutionary artifact, won newfound respect two years ago when researchers proposed that it actually serves a critical function.



Genetics: Large developmental leaps in evolution

Researchers demonstrate how genetic mutations and natural variations combine to produce twin spores in bacteria that normally produce only singletons.



Food Technology: Overfishing and evolution

The fish population in coral reef areas is often assessed by snorkelers or SCUBA divers, but new research shows that these methods may misrepresent the number of fish.



Genetics: Role for parasites in evolution of sex

What's so great about sex? From an evolutionary perspective, the answer is not as obvious as one might think. Sex may have evolved in part as a defence against parasites.
