New study finds the malaria parasite generates genetic diversity using an evolutionary 'copy-paste' tactic
By dissecting the genetic diversity of the most deadly human malaria parasite—Plasmodium falciparum—researchers at EMBL's European Bioinformatics Institute (EMBL-EBI) have identified a mechanism of 'copy-paste' genetics ...

Study on mating behaviors offers clues into the evolution of attraction
Sparks fly when a female nematode meets her mate in a Petri dish. Tracking him by smell, she beelines over and is pregnant within moments of physical contact. But for the hermaphroditic version of these tiny roundworms, it's ...

Not just humans: Bees and chimps can also pass on their skills
Bumblebees and chimpanzees can learn skills from their peers so complicated that they could never have mastered them on their own, an ability previously thought to be unique to humans, two studies said on Wednesday.

Synthetic DNA sheds light on mysterious difference between living cells at different points in evolution
"Random DNA" is naturally active in the one-celled fungi yeast, while such DNA is turned off as its natural state in mammalian cells, despite their having a common ancestor a billion years ago and the same basic molecular ...

Revealing the evolutionary origin of genomic imprinting
Some of our genes can be expressed or silenced depending on whether we inherited them from our mother or our father. The mechanism behind this phenomenon, known as genomic imprinting, is determined by DNA modifications during ...

Fossils of giant sea lizard with dagger-like teeth show how our oceans have fundamentally changed since the dinosaur era
Paleontologists have discovered a strange new species of marine lizard with dagger-like teeth that lived near the end of the age of dinosaurs. Their findings, published in Cretaceous Research, show a dramatically different ...

Study of slowly evolving 'living fossils' reveals key genetic insights
In 1859, Charles Darwin coined the term "living fossils" to describe organisms that show little species diversity or physical differences from their ancestors in the fossil record. In a new study, Yale researchers provide ...

Modeling the origins of life: New evidence for an 'RNA World'
Charles Darwin described evolution as "descent with modification." Genetic information in the form of DNA sequences is copied and passed down from one generation to the next. But this process must also be somewhat flexible, ...

Unraveling the mystery of chiton visual systems
You'd probably walk past a chiton without even seeing it. These creatures often look like nothing more than another speck of seaweed on the crusty intertidal rocks. But it sees you. At least, if it's one of the species with ...

Losing their tails provided our ape ancestors with an evolutionary advantage, but we're still paying the price
Put the word "evolution" into Google images and the results are largely variations on one theme: Ralph Zallinger's illustration, March of Progress. Running left to right, we see a chimp-like knuckle walker gradually becoming ...

Similar genetic elements underlie vocal learning in mammals
The vocalizations of humans, bats, whales, seals and songbirds vastly differ from each other. Humans and birds, for example, are separated by some 300 million years of evolution. But scientists studying how these animals ...
