Greetings to all, thanks for your participation here.
In recent months I’ve been learning about CRISPR, which you probably know is a new methodology which makes gene editing substantially easier. Jennifer Doudna won the Nobel Prize for her work on this. CRISPR imitates something bacteria have been doing for a very long time. It goes like this…
When a bacteria identifies an invading virus it grabs a bit of the virus’s DNA, and stores it within the bacteria’s own DNA. This allows the bacteria to more easily identify the virus the next time it attacks, and thus present a more effective defense.
That is, the bacteria is engaged in what we might call a data management operation. The bacteria grabs some information from the environment, stores that information, and then retrieves that information as needed for a specific purpose.
Bacteria don’t have brains or nervous systems. Bacteria are about 1/10,000th of a centimeter in size. And yet they are engaged in behavior which we would label as intelligent if we were doing it.
We might say that this behavior of bacteria isn’t intelligence but purely mechanical action which arose from evolution, natural selection. Ok, fair enough, but this just kicks the can down the road to another bigger mystery. If a human being had invented evolution we would have given them 99 Nobel Prizes, because evolution is a highly “intelligent” method of managing the relationship between living things and their environment.
Such CRISPR inspired reflection has led me to the question of the next post…
