...Committed - and to a certain extent, Powell's Cleaving - demonstrates the curse of the conversational writer. I confess to having found EPL tedious at times and to struggling with the fortuitous arrival of true love at the end of Gilbert's year of self-discovery. (In Committed, she pokes fun at herself, quoting her sister Catherine's response to her gushy e-mails from Bali: "Yeah, I was planning to go to a tropical island this weekend with my Brazilian lover, too ... but then there was all that traffic.") There was no denying, however, that she was a vibrant woman...
...pair of glasses. "There will be varying degrees of glasses," says Bratches. "You can buy glasses for 50 cents that look like you're sitting next to Jake and Elwood Blues, or you can buy a very high-end designer pair. They all do very different things." Be careful: certain glasses only work with certain 3-D sets, so grill the guy at Best Buy. (Watch a video about how 3-D movies are made...
...about Norrbotten, which was published in 2001 in the Dutch journal Acta Biotheoretica, he showed that the grandsons of Overkalix boys who had overeaten died an average of six years earlier than the grandsons of those who had endured a poor harvest. Once Bygren and his team controlled for certain socioeconomic variations, the difference in longevity jumped to an astonishing 32 years. Later papers using different Norrbotten cohorts also found significant drops in life span and discovered that they applied along the female line as well, meaning that the daughters and granddaughters of girls who had gone from normal...
More recently, however, researchers have begun to realize that epigenetics could also help explain certain scientific mysteries that traditional genetics never could: for instance, why one member of a pair of identical twins can develop bipolar disorder or asthma even though the other is fine. Or why autism strikes boys four times as often as girls. Or why extreme changes in diet over a short period in Norrbotten could lead to extreme changes in longevity. In these cases, the genes may be the same, but their patterns of expression have clearly been tweaked. (See the best pictures...
Geneticists are quietly acknowledging that we may have too easily dismissed an early naturalist who anticipated modern epigenetics - and whom Darwinists have long disparaged. Jean-Baptiste Lamarck (1744-1829) argued that evolution could occur within a generation or two. He posited that animals acquired certain traits during their lifetimes because of their environment and choices. The most famous Lamarckian example: giraffes acquired their long necks because their recent ancestors had stretched to reach high, nutrient-rich leaves...
