Natural organisms never had anything like source code. The genetic
code of an organism is more comparable to a binary (in fact,
quaternary) executable. Imagine a C compiler made by patching the
binary of hello.c a billion times in a genetic algorithm and you’ll
see how hard this is to understand. –in an answer to a question (question 14).

That’s a nifty insight that compares software and wetware!
