Is this open ended or long response? Personally I agree with Jordan because many creatures are highly adaptive. Humans only need about 3 days to get used to a different climate. Many organisms deal with changes in their environment like rainy and dry seasons or differing temperatures. On the other had you could agree with Leslie but only if the environmental changes were major enough to wipe out the populace. If rodents found around a river bank suddenly experienced a change like a flood many would die.
