Where did you come from and how does that affect who you are?
For one thing, possessing the knowledge that we share common ancestors can have the humanizing affect of enabling us to see past superficial differences and break down barriers.
Genetic knowledge can also help us understand a wide set of behaviors and why they exist. For instance, is there a gay gene? New research suggests so. If this research is confirmed, what are the implications? For one thing it would certainly put a decisive end to the nature versus nurture debate. Or would it?
According to geneticist Bryan Sykes, we're dealt a deck of cards in life. Those are our genes, and they have a major impact on who we are. At the same time, it's what you do with those cards that matters.
