English biologist and philosopher Richard Dawkins proposed the idea of “memes,” self-replicating patterns of information that propagate themselves across the ecologies of mind, a pattern of reproduction much like that of life forms.
I believe they are life forms in every respect but their freedom from the carbon atom. They self-reproduce, they interact with their surroundings and adapt to them, they mutate, they persist. They evolve to fill the empty niches of their local environments, which are, in this case the surrounding belief systems and cultures of their hosts, namely, us.
Indeed, sociobiologists like Dawkins make a plausible case that carbon-based life forms are information as well, that, as the chicken is an egg’s way of making another egg, the entire biological spectacle is just the DNA molecule’s means of copying out more information strings exactly like itself.
