In findings published in the February 8 issue of the journal Science, the researchers analyzed the world's largest dataset of genetic and physical traits to find that placental mammals diversified into present-day lineages much later than is commonly thought: after the extinction event 65 million years ago that eliminated non-avian dinosaurs. This finding, and the visualization of the placental ancestor -- an insect-eating animal that weighed less than a pound -- was made with the help of a cloud-based and publicly accessible database called MorphoBank.<br /> <br /> MorphoBank is an initiative funded primarily by NSF with additional support from Stony Brook University, the American Museum of Natural History, the National Oceanic and Atmospheric Administration, and the National Evolutionary Synthesis Center.<br /> <br /> Visit MorphoBank: <a href="http://mammaltree.informatics.sunysb.edu/">http://mammaltree.informatics.sunysb.edu/</a> Anti-Evolution 'Monkey Bill' In Tennessee tag:www.atheistnexus.org,2012-04-10:2182797:Video:1921634 2012-04-10T06:00:31.884Z Donegal http://www.atheistnexus.org/profile/Donegal <a href="http://www.atheistnexus.org/video/anti-evolution-monkey-bill-in-tennessee"><br /> <img alt="Thumbnail" height="180" src="http://api.ning.com:80/files/Z1v36mYeQ*Fs3VC8myAv540DELzn4IVO4FElv4I6Pflk8uAEXdfRAhEJikhtjzb43VjE854Qwmyr2E*xK5OSqbhHnBcb-Uhk/594574863.jpeg?width=240&amp;height=180" width="240"></img><br /> </a> <br></br>Via Think Progress: "Tennessee Gov.

But recent encounters between humpback whales and bottlenose dolphins reveal a playful side to interspecies interaction. In two different locations in Hawaii, scientists watched as dolphins "rode" the heads of whales: the whales lifted the dolphins up and out of the water, and then the dolphins slid back down. The two species seemed to cooperate in the activity, and neither displayed signs of aggression or distress. Whales and dolphins in Hawaiian waters often interact, but playful social activity such as this is extremely rare between species. The latest Bio Bulletin from the Museum's Science Bulletins program presents the first recorded examples of this type of behavior. Visitors to AMNH may view the video in the Hall of Biodiversity until February 9, 2012.<br /> <br /> Science Bulletins is a production of the National Center for Science Literacy, Education, and Technology (NCSLET), part of the Department of Education at the American Museum of Natural History.

A jawbone excavated in England and two molars found in southern Italy suggest that modern humans migrated northward thousands of years earlier than previously thought. These fossils were discovered and interpreted decades ago but recent analysis pushed back the age of the jawbone, while positively identifying the much-older molars as modern human. The latest Human Bulletin from the Museum's Science Bulletins program explains how this new data suggests a much longer period of interaction between humans and Neanderthals in northern Europe.
