Hey just because two things is related don't mean they come from a common ancestor! Ohhh wait a minute! It does! Holy mackerel! Wowza!
LOL.
Before he said African and Indian elephants weren't related. In other words, both having been placed by zoologists in the family elephantidae was just a naming trick to fool us into thinking they were related, just because they look sort of alike. Then when I showed him that they actually have been hybridized, he accepted that they were related, but won't describe what exactly related means in that context. As you say, it means they have a common ancestor. In other words, they are two species that were once a single species.
