winners and losers

Folks at UCLA have created a list of evolutionary winners and losers. They’ve based this list on a species’ ability to diversify over time. At the top of the winners list are birds (with 9,000 species) and mammals (with 5,400 species). Compare that speciation with big fat losers like crocodiles and alligators. Crocs and gators…

Epic Guinness Evolution Commercial

How we missed this the first time around I will never know, nor forgive our readers for. Enjoy! Thanks to Mike McElwain for sending along. yitb

The Evolution of Yarn

There’s no interesting news. It appears all the world’s animals have finally been discovered, their strange mating behaviors documented, and their interest in acting all crazy for YouTube evaporated. But we are undaunted. We will make the logical transition and become a knitting blog. Once again, we bring you critters from Mochimochi Land complete with…

Fascinating video from the PBS special, Dogs that Changed the World, on the changes that took place when foxes were bred for tameness in the former Soviet Union. This was originally posted on Greg Laden’s Blog but I had to repost it here.

Riddle of the Y-Larvae

A fascinating article in Livescience reveals the answer to a century-old zoological mystery: what do y-larvae grow up to become? Discovered in 1899, y-larvae are clearly young crustaceans but their adult stage could not be determined. While this in itself was perplexing, the newly discovered answer is even more startling: y-larvae metamorphosize into “simple, pulsing,…

Rapid Reptile Evolution

Scientists release seemingly harmless Italian Wall Lizards on a deserted South Adriatic island in 1971… and return to find walking, talking, boccie playing super-lizards! That is the headline that would have been written if researchers from the University of Massachusetts Amherst had waited only a few more years. In truth however, the scientists discovered that…

Lured out of the Gene Pool

A fascinating new study published in the Proceedings of the National Academy of Sciences suggests that the impact of human fishing may be reducing the fitness of fish populations overall. It may also explain why your grandfather insists that “the fish don’t bite like they used to.” The thinking goes like this: bold and aggressive…

First Flight, then Sonar

For years debate has raged amongst bat researchers as to whether or not bats were really just “flying rodents…”

Why do some creatures forgo their own reproduction to help their relatives survive and reproduce? While we all might like to believe that naked mole rats really do care and are thus willing to sacrifice their creepy little lives for the good of the colony, the true answer probably has more to do with gene…

Where Have All the Monster Bugs Gone?

Although most humans probably do not lament the disappearance of dog-sized insects, a handful of scientists do. These scientists obviously don’t watch the same movies we do. Recently, a group of researchers from Argonne National Laboratory’s Advanced Photon Source along with some other researchers from less badass sounding institutions used advanced x-ray equipment to try…
