The story of animal evolution is marked by key innovations such as limbs for walking on land, wings for flight, and color patterns for advertising or concealment. How do new traits arise? Sean B. Carroll, Ph.D. explores how new patterns evolve when 'old' genes learn new tricks. Old genes learning new tricks also apply to our own species and the evolution of traits that distinguish us from earlier hominids and other apes. Despite immense advances in evidence and understanding, there remains a societal struggle with the acceptance of our biological history and the evolutionary process. - ResearchChannel is a nonprofit media and technology organization that connects a global audience with the research and academic institutions whose developments, insights and discoveries affect our lives and futures.

Category: PoliticsPlan Colombia
What was the point of Plan Colombia? Is the U.S. government still concerned with fighting drugs? Why have 20 years of drug wars in the Andes resulted in a two-fold increase in cocaine imported into the U.S. in the last ten years alone? Could there be alternate purposes to a plan focused on beefing up the brutal Colombia military and spraying coca fields in rebel-held parts of the country when coca is grown all over Colombia? And what about oil, given that Colombia has the same oil potential as Venezuela, currently the second largest oil supplier to the U.S.? The award-winning Free Will Productions team sheds light on the complex issues of drug-trafficking and civil struggle in Colombia and the impact of both the current chemical-spray program and the multibillion dollar aid package delivered to the military. Analysis and interviews with Noam Chomsky, the late Senator Paul Wellstone, Colombian Presidential candidate Ingrid Betancourt (later taken hostage by the FARC), U.S. Members Of Congress John Conyers and Jim McGovern, U.S. State Department officials, a World Wildlife Fund scientist, as well as Colombians from all walks of life, including guerilla leaders.

Category: MysteryWho Built Stonehenge
Stonehenge, located on the Salisbury Plain in Southern England, has long been associated with Druids, a group of wise men present in England more than 2000 years ago. Still today at Summer Solstice, the longest day of the year, Druid celebrations are held at Stonehenge. But were they the actual designers?
Excavations underneath the stones have revealed artifacts, like antler horns, carbon dated at 4000 years ago. Bodies found buried nearby are of the same age. This rules out the Druids, as well as the Romans who followed them. This even pre-dates immigrant settlers from Europe. That leaves a primative people known as Ancient Britons, who lived at the start of the bronze age. Great precision was used in assembling the 15,000 tons of rock into circles. Did they have the know-how? Tags: Stonehenge Views: 857 Rating: Posted By: admin |
