The effect is usually compounding because of how evolution by natural selection works. For example, if gene A gives a tiny 0.1% boost and gene B gives a tiny 0.

The effect is usually compounding because of how evolution by natural selection works. For example, if gene A gives a tiny 0.1% boost and gene B gives a tiny 0.1% boost, the combined effect is a 0.2001% boost (slightly greater than the sum).
- riffraff 9y agoWhy would natural selection imply compounding?
- pdog 9y agoThe combined effect from multiple genes is either linear (assuming no interaction) or superlinear (assuming some interaction) because other nonlinear effects are difficult for natural selection to operate on. Natural selection is the only process known to cause adaptations.
- riffraff 9y agobut my question was, why should it be superlinear? Genes with linear interactions would still grant evolutionary advantages.
