At work.
Just think.
Worlds where spiders, scorpions and the like develope hinged and efficient 'Book' lungs and so are not just limited by amospheric properties.
Or where crustaceans such as the 'Land frab' and such evolve much earlier and become one of the dominant land based competitors.
Amonites learn to chemically crack water. Keeping the hydrogen in their shells to become fierce aerial predators.
The mutation that allows for placentas never happens and so Marsupials continue to dominate the wilds.
