Human brains unlikely to evolve into a 'supermind' as price to pay would be too high

1000pa (Dec. 7, 2011) — Human minds have hit an evolutionary "sweet spot" and -- unlike computers -- cannot continually get smarter without trade-offs elsewhere, according to research by the University of Warwick.

Researchers asked the question why we are not more intelligent than we are given the adaptive evolutionary process. Their conclusions show that you can have too much of a good thing when it comes to mental performance.

The evidence...

A vaccination against social prejudice

1000pa (Dec. 1, 2011) — Evolutionary psychologists suspect that prejudice is rooted in survival: Our distant ancestors had to avoid outsiders who might have carried disease. Research still shows that when people feel vulnerable to illness, they exhibit more bias toward stigmatized groups. But a new study in Psychological Science, a journal published by the Association for Psychological Science suggests there might be a modern way to break...

They call it 'guppy love': Biologists solve an evolution mystery

1000pa (Nov. 23, 2011) — Guppies in the wild have evolved over at least half-a-million years -- long enough for the males' coloration to have changed dramatically. Yet a characteristic orange patch on male guppies has remained remarkably stable, though it could have become redder or more yellow. Why has it stayed the same hue of orange over such a long period of time?

Because that's the color female guppies prefer.

"Sometimes populations...

Predators drive the evolution of poison dart frogs' skin patterns

1000pa (Nov. 21, 2011) — Natural selection has played a role in the development of the many skins patterns of the tiny Ranitomeya imitator poison dart frog, according to a study that will be published in an upcoming edition of American Naturalist by University of Montreal biologist Mathieu Chouteau. The researcher's methodology was rather unusual: on three occasions over three days, at two different sites, Chouteau investigated the number...

Whiskers marked milestone in evolution of mammals from reptiles

1000pa (Nov. 10, 2011) — Research from the University of Sheffield comparing rats and mice with their distance relatives the marsupial, suggests that moveable whiskers were an important milestone in the evolution of mammals from reptiles.

Using high-speed digital video recording and automatic tracking, the research team, which was led by Professor Tony Prescott from the University´s Department of Psychology, have shed light on how rodents...

Half-billion-year-old predator tracked: Multi-legged creature ruled the seas

1000pa (Nov. 8, 2011) — Researchers from the University of Saskatchewan and Royal Ontario Museum (ROM) have followed fossilized footprints to a multi-legged predator that ruled the seas of the Cambrian period about half a billion years ago.

"Short of finding an animal at the end of its trackway, it's really very rare to be able to identify the producer so confidently," said Nicholas Minter, lead author of the article on the study, which...

Hi-tech scans catch prehistoric mite hitching ride on spider

1000pa (Nov. 8, 2011) — Scientists at the University of Manchester colleagues in Berlin believe have produced amazing three-dimensional images of a prehistoric mite as it hitched a ride on the back of a 50 million-year-old spider.

At just 176 micrometres long and barely visible to the naked eye, the mite -- trapped inside Baltic amber (fossil tree resin) -- is believed to be the smallest arthropod fossil ever to be scanned using X-ray...

'Zombie' worms found in Mediterranean fossil

1000pa (Nov. 1, 2011) — Traces of bizarre, bone-eating 'zombie' worms have been found on a 3-million-year-old fossil whale bone from Tuscany in Italy. It is the first time the genus Osedax has been found in the Mediterranean, and suggests Osedax were widespread throughout the world's oceans 6 million years ago.

The new find, published in the journal Historical Biology, confirms what scientists have long suspected -- that Osedax were likely...

Researchers complete mollusk evolutionary tree

1000pa (Oct. 26, 2011) — Mollusks have been around for so long (at least 500 million years), are so prevalent on land and in water (from backyard gardens to the deep ocean), and are so valuable to people (clam chowder, oysters on the half shell) that one might assume scientists had learned everything about them.

"Here's this big, diverse group of animals, and we don't know how they were related to each other," said Casey Dunn, an...

Land animals, ecosystems walloped after Permian dieoff

1000pa (Oct. 25, 2011) — The cataclysmic events that marked the end of the Permian Period some 252 million years ago were a watershed moment in the history of life on Earth. As much as 90 percent of ocean organisms were extinguished, ushering in a new order of marine species, some of which we still see today. But while land dwellers certainly sustained major losses, the extent of extinction and the reshuffling afterward were less clear.

In...

Heart disease linked to evolutionary changes that may have protected early mammals from trauma

1000pa (Oct. 18, 2011) — Can a bird have a heart attack? A new study by researchers at the Perelman School of Medicine at the University of Pennsylvania suggests that cardiovascular disease may be an unfortunate consequence of mammalian evolution. The study, published in a recent issue of the journal Blood, demonstrates that the same features of blood platelets that may have provided an evolutionary advantage to early mammals now...

Robotic bug gets wings, sheds light on evolution of flight

1000pa (Oct. 18, 2011) — When engineers at the University of California, Berkeley, outfitted a six-legged robotic bug with wings in an effort to improve its mobility, they unexpectedly shed some light on the evolution of flight.

Even though the wings significantly improved the running performance of the 10-centimeter-long robot -- called DASH, short for Dynamic Autonomous Sprawled Hexapod -- they found that the extra boost would not have...

Oldest fossil rodents in South America discovered; Find is 10 million years older and confirms animals from Africa

1000pa (Oct. 11, 2011) — In a literal walk through time along the Ucayali River near Contamana, Peru, a team of researchers found rodent fossils at least 41 million years old -- by far the oldest on the South American continent.

The remains -- teeth -- showed these mouse- and rat-size animals are most closely related to African rodents, confirming the hypothesis that early rodents of South America had origins in Africa, said Darin Croft, an...

How life might have survived 'snowball Earth'

1000pa (Oct. 10, 2011) — Global glaciation likely put a chill on life on Earth hundreds of millions of years ago, but new research indicates that simple life in the form of photosynthetic algae could have survived in a narrow body of water with characteristics similar to today's Red Sea.

"Under those frigid conditions, there are not a lot of places where you would expect liquid water and light to occur in the same area, and you need both of...

Aquatic fish jump into picture of evolutionary land invasion

1000pa (Oct. 5, 2011) — Research sometimes means looking for one thing and finding another. Such was the case when biology professor Alice Gibb and her research team at Northern Arizona University witnessed a small amphibious fish, the mangrove rivulus, jump with apparent skill and purpose out of a small net and back into the water. This was no random flop, like you might see from a trout that's just been landed. The rivulus seemed to know...

Salty water and gas sucked into Earth's interior helps unravel planetary evolution

1000pa (Sep. 25, 2011) — An international team of scientists has provided new insights into the processes behind the evolution of the planet by demonstrating how salty water and gases transfer from the atmosphere into Earth's interior.

The paper was published in Nature Geoscience on September 26.

Scientists have long argued about how Earth evolved from a primitive state in which it was covered by an ocean of molten rock, into the planet we...
