...until you consider just how vast and energy-intensive the global food system is. More than 37% of the world's land is used for agriculture, much of it ground that was once forested--and deforestation is a major source of carbon. The fertilizer and machinery needed on a modern farm also have a large carbon footprint, as does the network of ships and trucks that brings the food from the farm to your plate. On average, it takes seven to 10 times as much fossil-fuel energy to produce and ship food as we get from eating...
Biologists have also found plenty of evidence to support Darwin's other major claim: that different species share a common ancestry. Over the past 15 years, for example, paleontologists have found several fossils of whales with legs, linking modern whales to their terrestrial ancestors. Besides studying fossils, biologists can discover the genealogy of species by looking at their DNA. The fossil record points to hippos and other hoofed mammals as being the closest living relatives of whales. So does their DNA. Our own DNA contains clues to the bonds we share with the rest of life - it turns...
...1900s, biologists succeeded in merging the newest biological developments at the time into a new vision of evolution known as the Modern Synthesis. Today a number of biologists argue that it's time for a new understanding of evolution, one that Pigliucci has called the Extended Evolutionary Synthesis. For now, they are fiercely debating every aspect of that synthesis - how important gene-swapping is to the course of evolution, for instance, and how gene networks get rewired to produce new traits...
...President of Communications Hanzi Zhang ’12, said. Datamatch 2009 marks the service’s 16th continuous year of operation. This year, HCS has launched new features that allow users to change their answers until the deadline, and also updated the Web site for a more modern look.

...Revolution” at 6 p.m., extends a similar welcome. “Do make a detour to Cabot to see their work,” she said. “The exhibition explores why Darwin still packs such a punch today and how he has become a modern icon.” —Staff writer Victor W. Yang can be reached at vyang@fas.harvard.edu...
