Red Queen effect

Wikipedia – The Red Queen hypothesis, also referred to as Red Queen’s, Red Queen’s race or the Red Queen effect, is an evolutionary hypothesis which proposes thatorganisms must constantly adapt, evolve, and proliferate not merely to gain reproductive advantage, but also simply to survive while pitted against ever-evolving opposing organisms in an ever-changing environment, and intends to explain two different phenomena: the constant extinction rates as observed in thepaleontological record caused by co-evolution between competing species,[1] and the advantage of sexual reproduction (as opposed to asexual reproduction) at the level of individuals.[2]
