Scars of Human Evolution

Our aching backs are proof of the evolution of human bodies according to professor Alan Mann. About 7 million years ago, our four-legged ancestors came down from the trees and began to walk upright. To make upright posture possible, hominids developed a curve in the lower back and this curve lets us balance our trunk and head over our hip joints and walk on two legs.

About 90% of all slipped and herniated discs occur in that lumbar curve. If this is a result of intelligent design, the designer needs to go back to the drawing board.

Mann also points out that many women have narrow birth canals and they require medical intervention during childbirth - an evolutionary problem or unintelligent design?

He also points out that many of us must have our wisdom teeth removed because they don't fit in our mouths.

You can read more of Mann's comments in an article titled The human evolution: Teach the children well in the Philadelphia Inquirer.

Unfortunately children in Kansas will be left behind in the teaching of evolution. Reuters is reporting:
After months of debate over science and religion, the Kansas Board of Education has tentatively approved new state science standards that weaken the role evolution plays in teaching about the origin of life.
