Last night I saw The Da Vinci Code for the first time. I had read the first chapter of the book some time ago and frankly it so did not capture my imagination that I haven't picked it up since. Years before, I'd read Holy Blood Holy Grail, the book…
As reported by Scientific American, Researchers have concluded that only 10,000 years ago, the human transition from living off the land to actively raising crops and domesticated animals was accompanied by an accelerated rate of evolutionary change. The pressure for this change occcurred because populations became highly concentrated compared to hunter/gatherer…
I received the following from a friend of mine, who sent it to his local paper as well. I’ve asked his permission to post it here, in its entirety. It concerns an issue which, while we may hope represents an unfortunate part of our history long outgrown, still rears its…
