How is genetic drift different from natural selection?
natural selection occurs because some alleles confer higher fitness, whereas genetic drift occurs because of sampling error.
natural selection has a stronger effect in large populations, whereas genetic drift acts primarily in small populations
natural selection is a mechanism of evolution, whereas genetic drift is not a mechanism but an outcome of evolution
natural selection tends to cause very rapid evolution, whereas genetic drift tends to operate on much longer time scales.
