This is my final column for the Planet-of-the-Apes series and my last piece for the Philadelphia Inquirer. It explains how viruses move around the evolutionary tree. This column was inspired by David Quammen's new book Spillover: Animal Infections and the Next Pandemic
Higgs discusses a great new science book he's reading. The author, David Quammen, will talk Tuesday night at the Academy of Natural Sciences.
Some years ago Penn Museum archaeologist Patrick McGovern discovered that wine goes back at least 7000 years. He's giving a talk Tuesday night on ancient wine and beer. A tasting follows.
Penn State Scientists are tracking wolf packs reintroduced to Yellowstone in to rebalance the region’s ecology. Survival has been a struggle – the wolves face long, frigid winters and are now being ravaged by several devastating diseases.
One of the more difficult aspects of evolution for some people to swallow is the notion that random copying errors in DNA can add up to anything useful.
Here's my column for this week. It also appeared in Monday's Philadelphia Inquirer:
Once DNA evidence made clear that all humanity came from Africa...
Scientists discovered that male killer whales are momma's boys, and this may tell us something about human menopause and longevity.
There's more to say about those extravagent claims regarding junk DNA. They're hyped, for one thing.
Last week scientists claimed a new project debunked the notion that some of our DNA is expendible. Evolutionary biologists say that's not necessarily so. We may yet have junk in the trunk.
Higgs has a crush on Venus, but being the cerebral creature that he is, he turns to science to find an explanation for her beautiful coloration.
Bill Nye the Science Guy says creationism is not suitable for kids. Says we need engineers. Is there a connection?
Anthropologists say only recently did we become the sole human species.
For those who actually "read" Playboy, Richard Dawkins answers some hard questions.
Mario Molina says even if we can't predict exactly how bad global warming will get, it would behoove us to do something about it.
