Have you ever wondered about the average life expectancy of a species? Well, I just read that the average life expectancy is about 100,000 years before the species become extinct. Judging by biological success, the lower the I.Q. the longer the life expectancy. For example, beetles and bacteria are vastly more successful than human beings in terms of survival of the species. Other than humans, no known life forms destroy their own biosphere as humans do. Self-destructive species start the extinction process by polluting the most essential resource - clean, potable water. While I am at it, did you know that tooth decay is caused by a bacteria passed on from mother to fetus. What does this mean? Well, you know, it is as meaningless as mitochrodrial DNA.
