The famous sequence that shows the evolution of man from knuckle-dragging ape to an upright human may be flawed, a new study has revealed. tags ancestors elvolve knuckle dragging apes evolutionResearchers who examined the wrist bones of several primate species believe our early human ancestors never used their knuckles to walk like gorillas. Instead they evolved from other apes who spent most of their time in trees and descended to the ground upright. picked by AutumnLotus 4 months ago |

Fossils recently discovered in Myanmar could prove that the common ancestors of humans, monkeys and apes -- known as anthropoids -- evolved from primates in Asia, rather than Africa, researchers contend in a study released Wednesday. picked by AutumnLotus 5 months ago 0 comments edit related share science |
As far back as Charles Darwin, scientists have noted that apes make characteristic sounds during play or while being tickled, apparently to signal that they're interested in playing. picked by kakana 6 months ago 0 comments edit related share science |

Researchers studied red columbines pollinated by hummingbirds, and white or yellow columbines pollinated by hawkmoths. They believe that a color shift from red to white or yellow has happened five times in North America. picked by AutumnLotus 5 months ago 0 comments edit related share plime.com |
You might think rocks and the minerals they are made of are rather boring. But a new study shows life has been integral to the evolution of minerals, giving rise to the majority of the 4,300 or so types present on Earth today. picked by AutumnLotus 1 year ago 0 comments edit related share science |
In preparation for Charles Darwin's upcoming 200th birthday, the editors of Nature compiled a selection of especially elegant and enlightening examples of evolution. They are, quite simply, wondrous — glimpses through an evolutionary frame of life's incredible narrative, expanding to fill every possible nook and cranny of Earth's biosphere. picked by 2manyusernames 11 months ago 2 comments edit related share science |

As the annual International Whaling Commission meeting stumbles to a close, unable to negotiate a compromise between whaling opponents and people who’ve killed more than 40,000 whales since 1985, scientists say these aquatic mammals are more than mere animals. They might even deserve to be considered people. picked by AutumnLotus 5 months ago 12 comments edit related share science |
In a study published in the recent issue of Science, researchers collected samples from eucrites found in Antarctica believed to have originated from Vesta. The researchers revealed that asteroid’s boiling rock turned solid and crystallized within less than 10 million years of solar system formation. picked by AutumnLotus 2 years ago 0 comments edit related share plime.com |

Why did humans evolve to walk upright? Perhaps because it's just plain easier. Make that "energetically less costly," in science-speak, and you have the conclusion of researchers who are proposing a likely reason for our modern gait. picked by AutumnLotus 2 years ago 0 comments edit related share science |

Children born in the winter months already have a few strikes against them. Study after study has shown that they test poorly, don't get as far in school, earn less, are less healthy, and don't live as long as children born at other times of year. Researchers have spent years documenting the effect and trying to understand it. picked by nateebiinature 2 months ago 17 comments edit related share plime.com |

Sandcastle worms live in intertidal surf, building sturdy tube-shaped homes from bits of sand and shell and their own natural glue. University of Utah bioengineers have made a synthetic version of this seaworthy superglue, and hope it will be used within several years to repair shattered bones in knees, other joints and the face. picked by AutumnLotus 1 year ago 0 comments edit related share science |
Paleontologists have long been perplexed by dinosaur fossils with missing pieces – sets of teeth without a jaw bone, bones that are pitted and grooved, even bones that are half gone. Now a Brigham Young University study identifies a culprit: ancient insects that munched on dinosaur bones. picked by mutil8or 2 years ago 0 comments edit related share science |
