I am a learning freak.
I know that you all know that, but I just needed to put it out there at the top of this entry. There have been two key events that occurred this week that have changed my perspective on the world.
On Thursday night, John and I went to a lecture on National Geographic’s Genographic project. It is headed up by an over-achieving, but brilliant man whose task is to identify the key mutations in our DNA, tying the mutations to population shifts over the last 60,000 years. It’s a little anthropology, a little geography, and a little population genetics. He collects the DNA via cheek swabs (who remembers looking at your cheek cells under a microscope?). In males, he looks the Y chromosome, in females the mitochondrial DNA (the “furnace” of every cell with old, minimally changing DNA). The collection efforts have been focusing on aboriginal tribes that are still maintained to this day, in order to identify the key markers. Enough markers have been found that pretty much anyone can have their cheek swabbed, and be told where their ancestors traveled in order to get you here. It isn’t a “you’re mostly German” test – you can get that from doing your traditional genealogy studying. This is, “your ancestors came out of Africa about 30,000 years ago, hung a right at the middle east, crossed over to the Americas about 18,000 years ago, and have been in Virginia since 10,000 years ago.” NUTS. All that info from your DNA. Blows my mind. If it blows yours too, check it out at: http://www.nationalgeographic.com/genographic
Last night, we sat down and watched An Inconvenient Truth – the documentary/environmental lecture by Al Gore. Wow. Those of you that haven’t seen it MUST. He has emphasized the fact that yes, we do make an impact on this world, every single one of us. And we’re getting to a point where the facts can’t be ignored. I know that all of us this year have been noticing the a-typical weather in our own neighborhoods. We in the Twin Cities have only gotten about 9” of snow this winter; we usually have 27” by now. Every one of us needs to make a change in our own practices to decrease CO2 emmisions. Please check out http://www.climatecrisis.net/, determine your Carbon Impact and make some changes. The safety of the world we live on depends on you. If we don’t watch out, we’ll have a mass extension of most of those genetic markers the first group is finding.
Thanks for learning with me.
