Randall Munroe’s latest comic at xkcd is a discussion about whether we’ve actually cracked the code of life. Sure, we know about DNA. On the surface, it seems so simple: only four bases in only two combinations. On the surface, it may as well be just digital code. However, it is digital code that not only makes up a living being with all its components, but also contains a lot of code that isn’t necessary (at least not that we know), but still tells the history of evolution. The most complicated digital codes we’ve written don’t hold a candle to DNA.
Did this comic cause you to view the source code for Google’s minimalist home page? I did. It was an eye-opener.
