It may be one of the most famous dinosaurs of all time. The trouble is that shortly after being discovered, the Jurassic creature fell into an identity crisis. The name for the long-necked, heavy-bodied herbivore Brontosaurus excelsus—the great "thunder lizard"—was tossed into the scientific wastebasket when it was discovered that the dinosaur wasn't different enough from other specimens to deserve its own distinct genus.
But now, in a paleontological twist, Brontosaurus just might be back. A new analysis of dinosaur skeletons across multiple related species suggests that the original thunder lizard is actually unique enough to resurrect the beloved moniker, according to researchers in the U.K. and Portugal.
Unlike many hipster trends, there is at least one that science may have successfully demystified. Men are growing beards to assert dominance over other men and appeal to women, a report suggests.
Those are the findings of a new study commissioned by The University of Western Australia, according to a report in the UK publication The Telegraph. Published in the journal of Evolution and Human Behaviour, researchers studied 154 different species of primates, and found many males developed "badges" that boosted their sex appeal and made them more attractive to the females of its species. ... Dr. Cyril Gueter told The Telegraph that the distinguishing characteristics among apes and monkeys correlated to beards in humans. The recent boom in male facial hair, Gueter says, is related to intra-societal competition among males.
