What animals are truly most like human beings? Humpback whales, who mate for life and communicate with complex, melodic songs? The upright-walking, chronic masturbator bonobo chimps? Bears, who seem to want to inhabit our homes and drive our cars? An article in today's New York Times points to a different answer, and one that shouldn't surprise anyone who's looked in the mirror lately. As Natalie Angier reports, "Last week, an international team of biologists released the first draft sequence of the pig genome." According to team-leader Lawrence Schook of the University of Illinois at Urbana-Champaign, "The pig genome compares favorably with the human genome."

Pig hearts are like our hearts, he said, pigs metabolize drugs as we do, their teeth resemble our teeth, and their habits can, too. "I look at the pig as a great animal model for human lifestyle diseases," he said. "Pigs like to lie around, they like to drink if given the chance, they'll smoke and watch TV."
