Last week, a man was beaten on a busy street corner in DC. The beating was violent and caught on videotape.

13:06Darwin's birthday: The evolution of Evolution
This year marks two significant dates in scientific history: the 200th anniversary Charles Darwin's birth, and the 150th anniversary of Darwin's landmark work, "On the Origin of Species." We speak with scientists from a variety of scientific disciplines about what Darwin got right, what he got wrong, and how his work still guides cutting-edge research today.
