The first detailed map of a human’s genes shows the genetic code is even more complex than anyone thought. For instance, science still cannot pinpoint what makes a person’s eyes blue.

Initial study of genome entrepreneur Craig Venter’s own DNA map shows 4.1 million places where his genetic code is different from the basic “reference” human genome.

This is many more than had been expected, including big differences that extend far beyond the single-letter changes that account for much of the variation seen so far.… 

The biggest surprise is we are lot more different from one another than we thought.
