Early Bird, centered at the Field Museum, examined DNA from all major living bird groups. Scientists built and analyzed a dataset of more than 32 kilobases of nuclear DNA sequences from 19 locations on the DNA of each of 169 species -- equivalent to a small genome project. in ScienceDaily...http://www.newsisfree.com/iclick/i,291516719,14592,o/ Canine Tooth Strength Provides Clues To Behavior Of Early Human Ancestors- (Found June 29, 2008 ) Measuring and testing the teeth of living primates could provide a window into the behavior of the earliest human ancestors, based on their fossilized remains. New research takes us one step closer to understanding the relationship between canine teeth, body size and the lives of primates. in ScienceDaily Headlines: Fossils & Ruinshttp://www.newsisfree.com/iclick/i,291516720,14592,o/ June 26, 1820: The Destroyer of Rocks- (Found June 29, 2008 ) This morn I rose at 4, and walking on the shore of the lake found several fine specimens of cornelian and agate.

The complex is comprised of the cosmopolitan species, D. simulans, and two island endemics, D. mauritiana and D. sechellia. A substantial amount of effort has gone into reconstructing the natural history of the complex, in part to infer the context in which functional divergence among the species has arisen. Researchers now provide evidence that both island species...http://www.newsisfree.com/iclick/i,291266050,14592,o/ |
