You're under the assumption that the current taxonomy structure has hard defined rules that nature follows because we humans told it to. Similar genus (homo is the genus) can interbreed even if they differ by species. But from what I understand, not all genus (gensuses? gensi?(I was educated that it's genera from a commentor)) follow that trait. Most can, some can't. Hell, there's a movement to ditch the current taxonomy structure and pick one of 2 other kinds that seem to follow evolution better than what we have right now. Wasn't subfamily or tribe originally called race back in the day? I could have sworn when I was in school it was called race. But they changed it at some point without sending me a memo.
