      Caribbean Monk Seal Extinct

      Caribbean monk seals, the sea dwellers first discovered during Columbus’s second voyage in 1494, are officially extinct—the only seal to vanish because of human causes, MSNBC reports. “Humans left the Caribbean monk seal population unsustainable after overhunting them,” a biologist explained.

      Homosexuality: It's Perfectly Natural

      It may throw a wrench in Noah's ark-stocking plans, but same-sex relationships appear in many animal species, reports LiveScience.com. The long list of animals that practice gay sex includes bears, penguins, gorillas, and dolphins, among others. But scientists question the act's evolutionary purpose, because it doesn't aid in reproduction. It may be an adaptation for nurturing offspring, or just a dry run. More »

      Fertile Women Sound Sexier, Study Says

      Barflies take note: A woman's voice is sexiest when she's most fertile, a new study says. Scientists recorded women counting from 1 to 10 and found that their voices were rated most attractive when they were closest to ovulation, the BBC reports. What gives? Researchers aren't sure, but they speculate that hormones may affect the voice box. More »

      Cougar's Long Trek to Chicago May Tell Tale

      A cougar shot April 14 in Chicago was spotted earlier in Wisconsin, DNA tests show, suggesting an epic trek. Now, scientists are eager to study the animal, hoping to learn more about how and why it migrated; they aim to pin down its ancestry in an effort to better understand how animals like it adjust to human populations, the Chicago Tribune reports.

      Darwin's Papers Now Online

      A vast collection of the papers of Charles Darwin is now online, providing public access to volumes once restricted to Cambridge scholars, the BBC reports. 20,000 items are available, including the first draft of his seminal book on evolution, travel notes and personal pieces such as family recipes, Reuters reports. “Darwin changed our understanding of nature forever,” says the project’s director.

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

      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 »

      Girls Think Pink, Naturally, Study Finds

      Shocking news: Girls love pink. That love might not just be cultural—but linked to evolutionary development, researchers  in a new study have concluded. Pink may have helped ancient women recognize ripe fruit and healthy men with ruddy faces, while both genders yearned for the blue of open skies and clear water, the Telegraph reports. More »
