Iceman Ötzi had bad teeth

The Neolithic mummy Ötzi (approximately 3300 BC) displays an astoundingly large number of oral diseases and dentition problems that are still widespread today. As Prof. Frank Rühli, head of the study, explains, Ötzi suffered from heavy dental abrasions, had several carious lesions – some severe – and had mechanical trauma to one of his front teeth which was probably due to an accident.

Moa's ark

Some of the largest female birds in the world were almost twice as big as their male mates. Research carried out by the Zoological Society of London (ZSL) shows that this amazing size difference in giant moa was not due to any specific environmental factors, but evolved simply as a result of scaling-up of smaller differences in male and female body size shown by their smaller-bodied ancestors.

The genetics of life and death in an evolutionary arms-race

Scientists at The University of Manchester have found evidence of the genetic basis of the evolutionary arms-race between parasitoids and their aphid hosts.

Sea urchin's secret to surviving ocean acidification

Stanford scientists have discovered that some purple sea urchins living along the coast of California and Oregon have the surprising ability to rapidly evolve in acidic ocean water – a capacity that may come in handy as climate change increases ocean acidity. This capacity depends on high levels of genetic variation that allow urchins' healthy growth in water with high carbon dioxide levels.

Birds find ways to avoid raising cuckoos' young

Some species of birds reproduce not by rearing their own young, but by handing that task on to adults of other species. Known as brood parasitism, this habit has been most thoroughly researched in the cuckoo. Previous research has found, however, that the nests of martins and swallows in Europe are rarely parasitized by cuckoos. A new study by Wen Liang from the Hainan Normal University in China a

No map, no problems for monarchs

Monarch butterflies have long been admired for their sense of direction, as they migrate from Canada and the United States to Mexico. According to new findings from a team of scientists, including researchers from the University of Guelph, the winged insects fly without a map, and use basic orientation and landmarks to find their way to their wintering sites, thousands of miles away.

Environmental change triggers rapid evolution

A University of Leeds-led study, published in the journal Ecology Letters, overturns the common assumption that evolution only occurs gradually over hundreds or thousands of years.

River dolphins use lower pitch sonar signals than marine dolphins, whales

Freshwater dolphins use echolocation signals that are quieter, more low-pitched and more frequent than those used by their marine counterparts, according to research published March 27 in the open access journal PLOS ONE by Frants Havmand Jensen from Woods Hole Oceanographic Institution and colleagues.

Dwarf whale survived well into Ice Age

Research from New Zealand's University of Otago detailing the fossil of a dwarf baleen whale from Northern California reveals that it avoided extinction far longer than previously thought.

Diversification in ancient tadpole shrimps challenges the term 'living fossil'

The term 'living fossil' has a controversial history. For decades, scientists have argued about its usefulness as it appears to suggest that some organisms have stopped evolving. New research has now investigated the origin of tadpole shrimps, a group commonly regarded as 'living fossils' which includes the familiar Triops. The research reveals that living species of tadpole shrimp are much younge

New fossil species from a fish-eat-fish world when limbed animals evolved

"We call it a 'fish-eat-fish world,' an ecosystem where you really needed to escape predation," said Dr. Ted Daeschler, describing life in the Devonian period in what is now far-northern Canada.

Controversial worm keeps its position as the progenitor of mankind

Researchers are arguing about whether or not the Xenoturbella bocki worm is the progenitor of mankind. But new studies indicate that this is actually the case. Swedish researchers from the University of Gothenburg and the Gothenburg Natural History Museum are involved in the international study. The results have been published in Nature Communications.

Tarsiers' bulging eyes shed light on evolution of human vision

After eons of wandering in the dark, primates developed highly acute, three-color vision that permitted them to shift to daytime living, a new Dartmouth College study suggests.

Researchers discover how model organism Tetrahymena plays roulette with 7 sexes

It's been more than fifty years since scientists discovered that the single-celled organism Tetrahymena thermophila has seven sexes. But in all that time, they've never known how each cell's sex, or "mating type," is determined; now they do. The new findings are published 26 March in the open access journal PLOS Biology.
