Macro-evolution is the theory that primordial slime eventually led to all the variety of life that we see today. For instance: a fish crawling out of the mud and it's descendants becoming a mammal.
On the micro-level there is plenty of evolution and this really is important. Examples would be a disease germ developing a resistance to an anti-biotic. Breeding fatter cattle.
