Allopatric speciation is duh, but sympatric speciation is confusing as hell. Well, skimming wikipedia, it seems like nobody understands it.

There's a wasp species that is bisected by a virus. Wasps with the virus can mate, w/o can mate, but no combinations are fertile.

Seems like sympatric needs something animal-specific to happen. Polar bears vs Kodiak is about fat metabolism genes.
