The smaller clumps each got their own share of the original total angular momentum, continuing down in scale so that everything today has some spin. (scientificamerican.com)
If you don't understand that the total angular momentum of a gas cloud is an aggregate quantity, but in fact there are local variations which can give rise to counter-spinning moons, and that in any case gravitational interactions between objects can produce retro - grade orbits then how in heavens name can you pretend to understand something as complex as evolution.

This adds to the individual spins to give a «total angular momentum». (newscientist.com)
