Today's Big Idea: The Genetics Revolution

What makes you who you are? Is it the decisions you make in life according to your own free will, or is your identity actually bound up in the DNA passed onto you from an ancient warlord?

According to Oxford geneticist Bryan Sykes, it is too deterministic to say "your genes determine everything you do." But they are "the deck of cards you are dealt at birth." It is your choice as to what to do with those cards. And yet, the DNA that you are made up of does come from somewhere.

For instance, if you are an African American you probably have European DNA. Some people don't like to hear this, as it changes their identity. And yet, according to Sykes, "I’m very proud of all of my ancestors that have got their DNA through to me, and I think everybody should be, particularly in America. Because all of you have ancestors that took a lot of trouble to get here, whether it was across the frozen wastes of Siberia or more recently on ships from Europe or, unfortunately, ships from Africa against your ancestors’ will."

Of course, genetics doesn't just tell us about the past. It can also help us predict the future. There are major benefits in health care that derive from knowing your genetics.

    The whole process of how we design and create future generations is changing. Your grandchildren, maybe your children, maybe even you, are going to reproduce differently than your grandparents did.
