WebbK-selektion. En stabil miljö leder till att individer som fortplantar sig långsamt men med stor investering per avkomma gynnas. Dessa tenderar att ha längre generationstider, längre liv, färre avkomma, större kroppar, större hjärnor, och vara territoriella.Reproduktionsorganen tar upp en mindre del av kroppen och de tillbringar mindre tid åt att reproducera sig.
