EVOLUTION: destroy factor and polution factor

[MateuszCOMPANY]

I have question about these two options
*Destroy factor* what's scale of affect? Killing bugs cause evolution in every camp, OR only in camp from where they come, OR just only for selected houses where they born?
*Polution factor* Its mean evolution progres only in camps touched by polutions OR its count our overal polution factor and causing evol. in every camp even dont touched by polutions?

Evolution is generally a global value. All emitted pollution counts for the pollution factor and only spawner kills count for the destroy factor. Evolution increase per pollution/kill is not constant, see https://wiki.factorio.com/Enemies#Evolution.
