    • Altruism Linked to Gene

      BBC  |  Dec 9, 07 6:35 AM CST

      Altruism Linked to Gene

      (Newser) - Researchers have identified a gene that may influence altruism, reports the BBC. Test subjects who had the choice of keeping money or giving it away were 50% more likely to give it away if they had a more active version of the gene AVPR1a. The gene is linked to arginine vasopressin, a hormone involved in social bonding. More »

      Religion Remains Flashpoint With Huckabee

      (Newser) - A month before the Iowa caucuses, Republican presidential candidate Mike Huckabee reacted with frustration when asked if creationism should be taught in public schools, the AP reports. Huckabee, a Southern Baptist minister who has said he does not believe in Darwin's theory of evolution, said his personal views on religion were irrelevant—though they remain a hot topic. More »

    • To Be, or Not: That Is the Question for Irregular Verbs

      Los Angeles Times  |  Oct 11, 07 10:44 AM CDT

      To Be, or Not: That Is the Question for Irregular Verbs

      (Newser) - Irregular verbs, much like the Kennewick Man, evolve. But, much like the woolly mammoth, sometimes they vanish altogether, and linguists and evolutionary theorists have teamed up to compute their extinction times—in terms of half-lives. The study, published this week in Nature , shows that irregular forms of lesser-used verbs are the first to become regularized. More »

    • What's Baby Got That Chimps Don't?

      Time  |  Sep 7, 07 12:05 PM CDT

      What's Baby Got That Chimps Don't?

      (Newser) - What makes humans smarter than their primate relatives? Into the ongoing debate comes a new study that concludes it's not just size, it's the particular kind of computing power. A study matching human toddlers with chimps and orangutans compared their performance on a battery of different kinds of tasks. The children were no better at "physical learning" —i.e. finding hidden objects—but miles ahead in "social learning." More »

      Lucy Debuts in Houston

      (Newser) - Lucy kicks off her public debut  at the Houston Museum of Natural Science tomorrow amid controversy that the world's favorite human ancestor should never have left her home in Ethiopia. The public wants the chance to the 3.2 million-year-old remains, but scientists say Lucy's too fragile to travel. More »

      Women Have Been Falling for Brad Pitt Types for 2.6M Years

      (Newser) - The facial proportions of the average hot guy haven't changed much throughout human  evolutionary history, finds a new study that compares contemporary human skulls with skulls from 2.6 million years ago. Women have been selecting for males with short, broad faces—think Brad Pitt and Will Smith—since the dawn of man, and chimps do the same. More »

      Kenyan Fossil Rattles Human Family Tree

      (Newser) - Two of our ancestors apparently lived alongside each other in Africa rather than evolving from one to the next on the path to Homo sapiens , as scientists once believed. National Geographic reports that a Homo habilis skull dug up in Kenya is surprisingly young, making its 1.4 million-year-old owner a neighbor to Homo erectus rather than an evolutionary forerunner.

    • Macho Men Seen as Cheaters, Poor Dads

      Reuters  |  Aug 8, 07 8:20 AM CDT

      Macho Men Seen as Cheaters, Poor Dads

      (Newser) - Macho-looking men are perceived as poor parenting material and more likely to cheat on their mates, according to recent study on sex and masculinity. "When people look at masculine faces they see dominance, which is a good thing in evolution but less good in a long-term partner," said the lead researcher. More »

    • Frozen DNA Survives After 8 Million Years

      Frozen DNA Survives After 8 Million Years

      (Newser) - Scientists have nixed the notion that glaciers are lifeless blocks of ice by thawing chunks containing Antarctic organisms and watching them successfully divide on their own, the Los Angeles Times reports. The study suggests that these microorganisms, ranging from 100,000 to 8 million years old, could yield DNA and spark an entirely new phase of bacterial evolution if warming continues to melt the glaciers.

      Why Fat is Phat

      (Newser) - Fat is underappreciated, New York Times health columnist Natalie Angier writes: just because a lot of people now have too much of it doesn't mean it should be villified. The fat cell is in fact a marvel of science, a sophisticated mechanism finely tailored not only for energy storage but to exchange complex chemical messages. More »

      Muslim Creationists Damn Darwin

      (Newser) - A Muslim group in Turkey is widely disseminating a 768-page tome that slams evolution and promotes Islam-inflected creationism, the Christian Science Monitor reports. The Council of Europe has issued warnings—particularly to schools—against the "Atlas of Creation," which has been published in 80 countries and 59 languages. More »

      The Mind Thinks More Than It Knows

      (Newser) - After just handling a stranger’s coffee, people make subconscious judgments about personality, psychologists say. Asked to hold a lab assistant’s cup of hot or iced coffee, Yale students associated cold drinkers with selfish personalities, the Times reports. The experiment is part of a body of research that leads to the conclusion that the brain has a mind of its own. More »

    • Butterfly Evolves in Blink of Eye

      Butterfly Evolves in Blink of Eye

      (Newser) - One of the fastest evolutionary changes ever observed has been witnessed by scientists studying butterflies in the South Pacific, the BBC reports. Blue Moon butterflies managed to fight off a deadly parasitic bacteria by developing suppressor genes to fight the bacteria in just six years. Hard-hit males rebounded from 1% of the population to 40% in that time. More »

      The Cat Did Not Walk by Himself

      (Newser) - Unlike most animals who were domesticated by man, cats, you cat owners will not be surprised to learn, domesticated themselves.  A study published in Science concludes that some 12,000 years ago cats, attracted by mice, who were themselves attracted by grain which man had just figured out how to cultivate, decided to settle down with us.

      Evolutionary Theory Takes Big Leap With Evo-Devo

      (Newser) - Evolutionary theory is in the early days of its third great expansion, the New York Times reports, following Darwin’s original formulation almost 150 years ago and the so-called “modern synthesis” of 1930-50. Dubbed “evo-devo” because it focuses on the embryonic development of organisms, the newest science explores how specific genes control significant aspects of an organism’s growth. More »

    • Early Immunity to Chimp Virus Leaves Humans Open to HIV

      Early Immunity to Chimp Virus Leaves Humans Open to HIV

      (Newser) - Humans are more susceptible to HIV than other primates because our ancestors evolved a protein that could fight off a different retrovirus that infected chimps, says Scientific American . The most conspicuous difference between the chimpanzee genome sequenced in 2005 and the human one, says a Seattle virologist, was 130 copies of a retrovirus that inserted its DNA into cells, as HIV does today.

      Big Bird Dazzles Paleontologists

      (Newser) - The largest birdlike creature on record stood over 16 feet tall, weighed a ton and a half, and had sharp claws but no teeth. The Chinese paleontologist who unearthed the creature's thigh bone wasn't sure what it was, he tells the San Francisco Chronicle, but as he listed the possibilities for a colleague he realized: "We have a gigantic chicken!"
