Mammoths Survived In Britain Until 14,000 Years Ago, New Discovery Suggests:
Research which finally proves that bones found in Shropshire, England provide the most geologically recent evidence of woolly mammoths in North Western Europe publishes June 17 in the Geological Journal. Analysis of both the bones and the surrounding environment suggests that some mammoths remained part of British wildlife long after they are conventionally believed to have become extinct.
Humans More Related To Orangutans Than Chimps, Study Suggests:
New evidence underscores the theory of human origin that suggests humans most likely share a common ancestor with orangutans, according to research from the University of Pittsburgh and the Buffalo Museum of Science. Reporting in the June 18 edition of the Journal of Biogeography, the researchers reject as "problematic" the popular suggestion, based on DNA analysis, that humans are most closely related to chimpanzees, which they maintain is not supported by fossil evidence.
Polar Bear And Walrus Populations In Trouble, Stock Assessment Report Suggests:
The U.S. Fish and Wildlife Service has released reports documenting the status of polar bears and Pacific walrus in Alaska. The reports confirm that polar bears in Alaska are declining and that Pacific walrus are under threat. Both species are imperiled due to the loss of their sea-ice habitat due to global warming, oil and gas development, and unsustainable harvest.
Size Did Matter: Evidence Of Giant Sperm Found In Microfossils:
The mystery of giant sperm present in some living animal groups today has now taken on a new dimension -- in one group of micro-crustaceans new evidence shows that it is a feature at least 100 million years old.
Sudden Collapse In Ancient Biodiversity: Was Global Warming The Culprit?:
Scientists have unearthed striking evidence for a sudden ancient collapse in plant biodiversity. A trove of 200 million-year-old fossil leaves collected in East Greenland tells the story, carrying its message across time to us today.
