From a science news story today:
A Swedish–Norwegian research team shows in a new study that the intestines of the peculiar Penis worm develop in the same way as those in humans, fish and starfish.If we didn't all come from the same source, why do we share many elements and traits with the "lower" animals? There is no doubt that evolution is real. People who don't accept the truth about our origins are either blinkered by religion or too lazy to think it through. Unfortunately, this describes most Americans.
