Earth's Moon May Not Be Critical to LifeMoffett Field CA (SPX) Feb 25, 2015 The Moon has long been viewed as a crucial component in creating an environment suitable for the evolution of complex life on Earth, but a number of scientific results in recent years have shown that perhaps our planet doesn't need the Moon as much as we have thought. In 1993, French astronomer Jacques Laskar ran a series of calculations indicating that the gravity of the Moon is vital to stabilizing the tilt of our planet. Earth's obliquity, as this tilt is technically known as, has huge repercus ... read more |

 Earth's Moon May Not Be Critical to Life Planets Can Alter Each Other's Climates over Eons The Cosmic Chemistry That Gave Rise to Water Calling on satellites in alpine rescues IPCC sea-level rise scenarios not fit for purpose for high-risk coastal areas How does the human brain tackle problems it did not evolve to solve? | .. |
 Swimming reptiles make their mark in the Early Triassic Vertebrate tracks provide valuable information about animal behavior and environments. Swim tracks are a unique type of vertebrate track because they are produced underwater by buoyant trackmakers, ... more | .. |
 Giant ancient rodents used incisors like tusks South America is known as home to some of the world's smallest (and cutest) animals, like the world's smallest anteater, the silky anteater, and Earth's smallest monkey, the pygmy marmoset. But the continent once hosted the world's largest rodents. ... more | .. |
 Ancient 'genomic parasites' spurred evolution of mammalian pregnancy An international team of scientists has identified large-scale genetic changes that marked the evolution of pregnancy in mammals. They found thousands of genes that evolved to be expressed in ... more | .. |
 Paleontologist names 9-foot-long 'predator croc' that preceded dinosaurs Finding a new species of dinosaur is pretty rare. Getting a hand in the discovery and naming of one - that's rarer still. Or it would be for anyone other than 32-year-old Sterling Nesbitt, an assist ... more |

 Tiny plant fossils a window into Earth's ancient landscape Minuscule, fossilized pieces of plants could tell a detailed story of what the Earth looked like 50 million years ago. An international team led by the University of Washington has discovered a way ... more | .. |
 Modern genetics confirm ancient relationship between fins and hands Paleontologists have documented the evolutionary adaptations necessary for ancient lobe-finned fish to transform pectoral fins used underwater into strong, bony structures, such as those of Tiktaali ... more | .. |
 Rods and cones preserved in ancient fossilized fish eye Rods and cones, the two main photoreceptor cells, are vital to human sight - converting visible electromagnetic radiation into information our brains can use. And it turns out, the biological technology has been around for more than 300 million years. ... more | .. |
