I don't have a definitive answer to that old evolutionary theory question, but I wanted to cite this one bit of data from that Iraqi terrorist who evidently tripped and blew himself up in Sweden:
In a recent profile he placed on an Islamic dating Web site, Muslima.com, the younger Mr. Abdaly appears as a tall, stern-looking, neatly dressed man standing in front of a white curtain, his dark hair cropped short, with a trimmed black beard.
“I am married since 2004,” he said on his dating profile, according to a translation of the original Arabic. He described himself as “very religious” and said that he had two daughters, aged three and one. “I want to get married again,” he said, “and would like to have a BIG family. My wife agreed to this."
