Again, that implies direction. There is no direction or purpose to evolution.
With all due respect...I think that's too general a statement. Yes, mutation themselves are random, but the optimization aspect of evolution imposes constraints. Some paths through the parameter space should be more favored than others.
Something like genetic algorithms as used in designing VLSI layouts. There is certainly a directionality or purpose there.
As to purpose in evolution, that's a philosophical or theological discussion, not a scientific one.
