#4050·Dennis Hackethal, about 22 hours agoSome people (most notably Ella Hoeppner) have argued that replication isn’t necessary for evolution to take place. All you need is variation and selection.
3) From what I’ve seen, the attempt to remove replication from evolution doesn’t actually remove it.
If you take some string of information and vary it, then by definition, only parts of it become different. Other parts are preserved. Even if you vary the string several times, the parts that didn’t change were still instantiated at each stage. So they still replicated. (As I recall, this is how Richard Dawkins defines what a gene is, in his book The Selfish Gene.)
Also, just by thinking about the string of information and how to vary it, you’ve already replicated the information. It now exists in its original medium and in your mind.
