<HTML>I saw this 2 nights ago on "Ripley's".
THIS is a GREAT example of "natural selection" in motion. This tribe only breeds with its own members. Their mutation, as a result of forced in-breeding, has become rampant throughout the tribe, and is quite fascinating.
"Ostrich People – Talk about a close family! The Vadoma people in Zimbabwe never allowed marriage outside of their own group. This practice caused a genetic deformity to develop over the generations. The Vadoma people's hands have only two fingers and their feet are v-shaped with two toes. Today the deformity is being slowly bred out of the tribe."
Now, if this deformity had given them ANY natural advantage over other tribes in the area (the ability to run faster or catch prey or gather more fruits) it is VERY easy to understand that their tribe would prosper and reproduce more than other tribes... so they would become the dominant genetic model for humans... and we'd all eventually have 2 toes and 2 fingers.
Need we see any more?
Natural selection in action. It's a beautiful thing.</HTML>
