This short piece here talks about the Human DNA, it's quite fascinating(as Spock would say). Most of the info here is stuff pretty much we should have all learned in HighSchool but its a great refresher and it highlights and ask some poignant questions.
Enjoy and pass along and Learn or shall I say rediscover. I feel like I'm Mr. Wizard haha.
