Lateral gene transfer.
Crossing over, different allele combinations (recombination/independent assortment), and gene flow all create genetic variation in humans. Lateral (horizontal) gene transfer is common in bacteria but is not a normal source of variation among human populations (except for rare, negligible events such as viral insertions).
