You could say that about any medical procedure. You could say that about computers... Testris would happen naturally if there were no significant trade offs.

You could say that about any medical procedure. You could say that about computers... Testris would happen naturally if there were no significant trade offs. Evolution tends to optimize, but it also gets stuck in local maxima because of its slow linear nature. We should eventually be able to provide vastly superior biological constructs and fixes - once we become proficient at reprogramming at a DNA/RNA level.
