I wonder what the transmission rate of information through genetic evolution is.
Kilo base pairs among other things.
Over time, yes, but I suspect the per-second bitrate is extremely small.
Do not forget parallelism. Neural networks, electronic circuits, and a lot of other processes in nature occur simultaneously at an enormous scale.
