The Common Harbor Seal

Every organism is a relation to some extent to every other organism, because as far as we're aware, life only started once on Earth and has just been forking ever since. So the harbor seal, common harbor seal, you'll find them in Scotland, is in theory, a distant relation to all humans. And so why is there someone who looks like his mum with his dad's surname? That means that his parents must be related. But yet, the genes that influence appearance somehow have to end up in his mother's ancestral line for that to make any sense. Can we talk about Back to the Future? My answer is so boring. You can totally change the conversation.
