Remember, it's only 14 days of dark. And 14 days of light.

And the atmosphere wouldn't be thinner. Same "sea level" pressure as Earth. In fact, because of the lower gravity, pressure drops off more slowly with altitude.

That 14 days of light should help the plants grow faster and build up reserves for the night.

I expect some animals will do long naps/short hibernations to deal with the long nights.

Come to think of it, I can see some plants having "fruit" with high levels of "slow burn" nutrients to encourage animals to eat them and carry seeds around.

I see a lot of critters caching the fruit in their dens. So it'd be advantageous for the seeds to be able to germinate and grow from deep underground.

BTW, there probably won't be a lot of adaptations from animals, because they haven't been on the moon long enough. I don't see terraforming happening more than a few hundred thousand years ago.

The plants will have a lot more generations to adapt.

Of course, a few 100k years ago puts us in an ice age. That *would* give the plants and animals a head start on adapting.
