Finding the Origin of Life
There are numerous theories about how life began on Earth. One thought is that it sprang up in the warm waters of a pond. Another suggests it arrived via comets. A different theory says life sprang from lightening and volcanoes. Scientists demonstrate that a spark of electricity applied to a primordial soup forms amino acids--the building blocks of life.
