Well, Jed's story says that we can "store" exabytes of data. Nowadays, we only use the "coding" part of DNA to figure out the amount of "information". Scientists erroneously assume the non-coding parts are "junk DNA" that have no information. That is not true. The non-coding parts are not Junk. Newer research are indicating that all of our DNA have functions we still do not know or understand. If they have function, they contain information we don't know about yet.

Nor are there exabytes of information encoded in our DNA, at least not in a single copy of our set. It's far, far less than that. The human genome is around 1.5 GB according to this source: http://www.genetic-future.com/2008/06/how-much-data-is-human-genome-it.html It couldn't be exabytes because it was sequenced by 2002, when exabyte-scale storage did not exist. I doubt they stored the raw data the sequence was derived from. The entire genome is copied in every cell, so the total amount of information per body is ~1.5 GB * 100 trillion cells per body. That would be 140,000 exabytes (136 zettabytes). Abd is correct that natural selection is not a random process. This is a widespread misunderstanding. - Jed
