Origin and evolution of life

  • Yeah We’re Movin on Up…
    The most comprehensive analysis ever performed of the genetic relationships among all the major groups of snakes, lizards, and other scaly reptiles has resulted in a radical reorganization of the family tree of these animals, requiring new names for many of the tree's new branches.

  • The Primordial Womb
    Arizona State University geochemist Lynda Williams and her colleagues have discovered that certain clay minerals under conditions at the bottom of the ocean may have acted as incubators for the first organic molecules on Earth.

  • King Kong… Almost
    A gigantic ape, measuring about 10 feet tall and weighing up to 1,200 pounds, co-existed alongside humans, a geochronologist at McMaster University has discovered.

  • Engineering Aliens
    What would you call an alien if you encountered it on the street tomorrow? What if that alien didn't come from another world but rather was created in a laboratory right here on Earth and functioned differently from other Earth life?

  • The Bee Matrix
    Bees have a much more sophisticated visual system than previously thought, according to a new UCL (University College London) study in which bees were able to solve complicated colour puzzles. The findings shed light on how brains resolve one of the most difficult challenges of

  • One, Two, Threes not ABCs
    Monkeys have a semantic perception of numbers that is like humans' and which is independent of language, Duke University cognitive neuroscientists have discovered. They said their findings demonstrate that the neural mechanism underlying numerical perception is evolutionarily primitive. Jessica Cantlon and Elizabeth Brannon described

  • One Man’s Junk is Another Man’s Treasure
    Genetic material derisively called "junk" DNA because it does not contain the instructions for protein-coding genes and appears to have little or no function is actually critically important to an organism's evolutionary survival, according to a study conducted by a biologist at UCSD.

  • Wright Bros. Tapped Dino Collective Unconscious
    The evolution of airplanes from the Wright Brothers' first biplanes to monoplanes was an inadvertent replay of the much earlier evolution of dinosaur flight, say two dino flight experts.

  • Rewriting Evolution
    The recent discovery of a 90-million-year-old dinosaur in Patagonia demonstrates that dromaeosaurs, a group of carnivorous theropods that includes Velociraptor and is closely related to birds, originated much earlier than previously thought.

  • Smart Ladies
    For the first time ever, scientists have observed and photographed wild gorillas using tools, in one instance employing a stick to test the depth of a pool before wading into it, according to a study by the Bronx Zoo-based Wildlife Conservation Society (WCS) and other

  • By Design
    Brother Guy Consolmagno, astronomer to the Vatican, discusses his views of the controversy over intelligent design, as well as the historical clashes between science and religion.

  • The Human Chimp DNA Divide
    Comparisons of the human genome and the newly completed draft of the chimpanzee genome have unearthed major differences between the patterns of large duplicated segments of DNA in the two species.

  • DNA Sunscreen
    Chemists at Ohio State University have gained new insight into how sunlight affects DNA. And what they found overturns ideas about genetic mutation that originated decades ago.

  • Quadrupeds to Bipeds
    The embryos of a long-necked, herbivorous dinosaur are the earliest ever recorded for any terrestrial vertebrate and point to how primitive dinosaurs evolved into the largest animals ever to walk on earth.
