Unless the change reduces the amount of sentient life that an ecosystem can support (e.g. by reducing net primary productivity), I’d expect a random change to also favour r-selected species (low investment parenting, large numbers of offspring, high mortality) over K-selected ones (the opposite of r-selected), since they can adapt more quickly due to shorter and wider generations.
I’m not sure what this says about climate change, since it plausibly also affects net primary productivity.
