Old Blue Eyes

Are they just making this stuff up as they go along? OK, I’m not a scientist and maybe my analysis is simplistic. But I am a student of responsible language and of logic. This just seems to be completely illogical.

A group called The Innovations Report ran a report called Blue-Eyed Humans Have a Single, Common Ancestor in which Professor Eiberg from the Department of Cellular and Molecular Biology made this claim:

Originally, we all had brown eyes, but a genetic mutation affecting the OCA2 gene in our chromosomes resulted in the creation of a “switch”, which literally “turned off” the ability to produce brown eyes.


The article goes on to explain how this switch turned off in the genes of this ancient person by saying “Nature shuffles our genes”.

Huh? That’s it? It happened because nature suddenly decided to “shuffle” our genes?! Was it a riffle shuffle or the classic hindu shuffle? [that was sarcasm]

A watered down version of the article made it to various major news agencies, like the LA Times which had this to say

For nearly all of human history, everyone in the world had brown eyes. Then, between 6,000 and 10,000 years ago, the first blue-eyed baby was born somewhere near the Black Sea. For some reason, that baby's descendants gained a 5% evolutionary advantage over their brown-eyed competitors, and today the number of people with blue eyes tops half a billion.


What? How do they know that? How can they pin point the location of the first blue-eyed baby. Read the articles for yourself and see if it passes the logic test. It doesn’t for me.

So if I reject this theory; what’s my alternative theory? Good question; and yes, I have an answer. Look for my post called Natural Selection.
