There would probably only be deep sea animals, I saw a few articles saying that there would drastic weather changes, and that it could easily get really hot or really cold. Even to the point of there being another ice age. I bet even without an ice age happening a lot of stuff would die off from temperature swings and probably wouldn't be able to adapt fast enough.

Not on land probably, but definitely at sea.

Tides helped life get on land forcing sea creatures develop amphibian skills. If no moon, they would have stayed in sea most likely.

I think so, but there's a lot more about how life can start we'll need to learn before we'll know for sure. Check back with me after we've colonized our third planet and have discovered alien life.

Probably not..
In fact earths orbit and angle to rotation was stabilized by the creation of our moon, it also created the tides which are affected by it's gravitational pull..

Scientists says that at least one comet seen so far that is made up of amino acid along with some other substances. So it can be thought ingredients of life have from outside of earth if rather than living body as a whole has not come from outside of earth. Finally it has got the then favourable environment to flurish the living body.

I saw a show on the science channel on this subject. I don't remember if their conclusion was doubtful or a big no. I don't remember how they came to that conclusion. I'm sorry I brought it up.

I have heard that it wouldn’t have. Apparently we need those tides and such.

While I don't doubt the moon played a role in how life appeared and evolved, I don't see its existence as a requirement for life to have appeared on Earth.

Abiogenesis would most likely have occurred without the moon, just differently than with the moon.
