This question already has an answer here:

I'm planning on making a "new world", in a new planet. This planet would have similar living conditions to the Earth, but two moons (both in the same orbit, so that both can be seen at night), but I want to know how that works. How would it affect the planet? (I mean, in terms of wildlife and atmosphere).

The other question listed as a duplicate doesn't answer my question. I'm wondering about wildlife, and the other is about tides.

Thanks!

    $\begingroup$ Your first question might already have been asked on this site. worldbuilding.stackexchange.com/questions/71/… Many planets have multiple moons. All it would take is having one with liquid water to ALSO make it viable for life... the two moons can orbit at different distances and would never (or rarely) meet. $\endgroup$ – Isaac Kotlicky May 29 '17 at 23:03

    $\begingroup$ Two moons don't make the night brighter, only if their surface area is larger then our moon, if both are significantly smaller the nights would actually be darker. In itself they have no direct impact, they can impact the the world which would impact evolution but it's not the moons directly. As for alternate evolution, that's far to broad to ask here. $\endgroup$ – Mormacil May 30 '17 at 22:44
