Materealism cannot provide a logical foundation for morality.
This is because for morality to happen, one needs to be able to draw a line between people, who should be treated morally, and inanimate objects that shouldn't.
Since materealism is a monistic system, it cannot draw this line.
The criteria of complexity is ridiculous - a human being is more complex than a stone, true. But a robot, in theory can be as complex than a human being. Still, it won't make him an object of morality. (Remember Asimov's first law?). The universe as a whole can be said to be as complex as a human being. Yet, it is not a moral object. (Moral object = an object that should be treated morally).
Replication is also a bad criteria - crystals are not an object of morality. Neither are computer viruses. Or memes. Or robots that can build other robots.
In fairness, any monistic system faces this problem, not just materealism. Systems that believe that "only spirit exists", or "everything is one", or "everything is god" have exactly the same problem. They are unable to draw the line.

To clarify, that was a philosophical point. I do not think that monists are less moral than non-monists, and that materealists are less moral than non-materealists. I do not know why this is so. But the facts show it is.
