Genes on the Move

Biology class is all about putting living things into categories, based on their differences. And creatures are different because they have different genes. But life wasn’t always like that. In this segment, Steve Strogatz, an applied mathematician at Cornell, tells us about a radical theory that says that way back at the beginning of life, 3 billion years ago, life was a big commune of gene swapping. Nigel Goldenfeld, one of the scientists who came up with this theory, says that the idea of different species, and consequently Darwinian evolution, simply didn’t apply for the first billion years of life on Earth. Then we follow the thread of an essay by Freeman Dyson called "Our Biotech Future." According to Dyson, the rise of biotechnology means that there will be an explosion of new life forms, that we will start moving genes from one creature to another. So we go to MIT, where Steven Payne and Reshma Shetty prove Dyson’s point by making stinky bacteria smell nice.

I caught a good portion of the "Genes on the Move" program on Thursday, March 6th at around 2:45pm Central Time listening to MPR and was immediately enthralled. I am teaching this very topic and these very ideas to my sophomores in Biology right now. Your information was very cutting edge and I would LOVE to have this audio program for my students to hear. Is there any way that I could get a copy of the program so my students could listen to and learn from this dynamic and tantalizing show?!

Seth ... The show will be available for download in a couple weeks. It doesn't get released on our website until after it plays on our home station, WNYC. But we'll put up a blog on the front page of the website as soon as it's available for download.

And if you do use it with your students, let us know what you did and how it went ... we're more likely to see your message and respond in a timely manner if you send your thoughts to radiolab@wnyc.org.

Thanks for listening.

Soren.

Is there a way to get the bio-engineer song that is on this segment? It is great!

This was a fabulous episode. The bio-engineer song was hysterical. I was laughing uncontrollably and dancing in my car--the people around me must have thought I was mad. If only they knew I was listening to NPR.

I agree that this was absolutely enthralling, and I loved the way the music illustrated the concepts. I eagerly await your posting this program as a podcast.

Not only was this entire episode captivating, but the bio-engineer song was a riot. If I wasn't driving at the time I would have written those lyrics down.

When this episode comes out for podcast you must add that song as an MP3!

Seth,

I agree with you that we are like a living computer with the potential for 'widgets' that may be added. I hope the public continues to support the sciences and thank you for your program!

I also loved the song of bio-engineers song - if the artists are willing, it'd be fantastic if they made it available.

I am part of the first graduating class of bioengineers at the University of Illinois. Is there any way we could get a copy of this song to use at our graduation? (the bioengineer one)

I found it dangerous propaganda to pave the way in terms that don't challenge, debate, scrutinize, only smooth it over. Make NO mistake, these are students being USED in the agribusiness machinery to help profits...EVERYTHING is about money. Please don't insult discerning listeners that is about some greater good. Natural selection worked for millions of years, weeding out the weak, nourishing the strong, until the industrial age of greed, and dominating nature for profit. That , and that alone, IS what this so called science is about.Market share, invstment, and using students with industry funding that helps keep land grant and other universities in "business."

I am disgusted and terrified at the arrogance of the bioengineers in this story. As a wildlife biologist, I see the potential for these guys to end life as we know it on our planet. The world's fauna and flora are already battling for survival due to the pressures of humankind and the introduction of non-native invasive species into native ecosystems. Many of our native plants and animals could be wiped out by bioengineered species run amuck. Play with viruses and bacteria, and we humans could be the first of the casualties.
