Instead, random "genetic drift"is the likeliest reason for these skull differences. First-ever 'State Of The Carbon Cycle Report'Finds Troubling Imbalance
The first "State of the Carbon Cycle Report"for North America finds the continent's carbon budget increasingly overwhelmed by human-caused emissions. North American sources release nearly 2 billion tons of carbon into the atmosphere each year, mostly as carbon dioxide. Carbon "sinks"such as growing forests may remove up to half this amount, but these current sinks may turn into new sources as climate changes. Video: iPhone Apps for Shutterbugs

Relationship Between Environmental Stress And Cancer Elucidated
One way environmental stress causes cancer is by reducing the activity level of an enzyme that causes cell death, researchers say.
