alvarez hypothesis [(al-vuh-rez)]
the theory that the m-ss extinction that involved the dinosaurs and many other living things was caused by the impact of a large asteroid on the earth sixty-five million years ago.
note: the hypothesis is named after the father-and-son team of scientists luis and walter alvarez, who first suggested it.
note: evidence indicates that the asteroid fell in the yucatan peninsula.
