A lot more than that, since evolutionary changes come about due to random variations that happen to make an individual more successful than others at passing on their genes. In other words, you need time for variations to occur, and time for the less successful variants to produce fewer offspring or die before reproducing, while the more successful breed like bunnies and live long, healthy lives.
Some people question whether modern medicine and modern society have effectively stopped human evolution.

By your "logic" everyone on the American continents should now have bronze skin, black hair and brown eyes, regardless of their ancestry.
