Using DNA to Send Messages into the Distant Future

This article discusses recent research into encoding short 100 word messages into the DNA of living organisms. The error-correcting characteristics of DNA enable such messages to be passed down without degrading across generations. By embedding short messages into hardy organisms such as particular strains of bacteria, it may be possible to preserve information over longer timeframes than by using any other known storage media. This in turn can be used to intentionally send messages into the far future. I blogged about this over a year ago, here, where I suggested that because this is possible, we might want to look to see whether any such messages are already there in our own DNA or that of particularly hardy organisms. Perhaps someone put their signature there for us to see a long long time ago? Perhaps the best way to create a time capsule that can last for thousands or millions of years would be to embed messages across the DNA of a bunch of different organisms in different ecoological niches, to ensure that at least some would get through to the future. Certainly a few strains of bacteria should be included, as well as perhaps cockroaches, some types of fish, some plants, and perhaps even some volunteer humans. Since the message has to be pretty short, I would suggest that we use it to indicate the location of one or more hidden storage locations on the planet (or on the moon?) where larger volumes of information, technology, DNA libraries, etc., could be located. I view this as a kind of global "backup strategy" not unlike backing up a hard-disk. I once had some thoughts about doing this using special satellites as well, which you can read about here.

    Link: Minding the Planet: Using DNA to Send Messages into the Distant Future. This just seems creepy to me. What would be so important that this would be required? My thinking is, that if we’ve lost certain info or technology
