slash UK slash AI for people. Welcome to Science Talk, the weekly podcast of Scientific American

for the seven days starting April 9th, 2008. I'm Steve

Mirsky. This week on the podcast, it's movie talk. We'll discuss the new film Expelled,

in which Ben Stein tries to make a case that academics are being persecuted for subscribing

to what he contends is the valid scientific theory of intelligent design,

which can be the idea that some aspects of life are irreducibly complex and could not have evolved

without some help from an intelligent force, or that the entire universe shows signs of intelligence in its makeup.

The film also castigates evolution, which describes how organisms descend with modification

from common ancestors.

A more modern definition for evolution is the change in the gene pool of a population

from generation to generation by such processes as mutation, natural selection, and

genetic drift.

Scientific American editor-in-chief John Rennie and I saw the film expelled, and we'll share our thoughts,

and then we'll hear from Eugenie Scott, the director of the National Center for Science Education,

who is actually in the movie.

Plus, we'll test your knowledge about some recent science in the news.

First up, John Rennie and me, we talked in his office at Scientific American.
