Does your family have a crazy uncle?
Perhaps you have a cousin?
Don’t assume everyone has a cousin. As families shrink, as the human population contracts (and it will) the chances of having a cousin will shrink.
Having a cousin used to mean you shared a grandparent with that person, usually two grandparents.
In today’s society, with halves and steps and mixing of marriages, there’s a chance your cousin is in name only. You may not share an ancestor within a thousand years of each other.
However, that’s not the point. In a biological sense, we are all related. That’s the whole point of being a species. Humans are part of a single species we call humanity. Everybody within a species is supposed to be able to marry anyone else within the species. Please don’t try to marry someone outside your species!
Some scientists say that modern humans may have married Neanderthals back when they still rented rooms in Europe. If that’s true, and they had kids, then they must also been part of our species.
No other animal has special names for relatives. The most family other animals care about is Mom, Dad, and Kids. And for most other animals, once the kids are adults, they aren’t part of the family anymore.
Humans seem to be unique in this way. We keep track of aunts, uncles, cousins, nieces, nephews, grandparents, second cousins twice removed, and possibly even more. In some languages there’s a word for my mother’s father’s brother.
What’s the benefit of tracking these relationships?
Power. Pure and simple. If you can name someone that can help you get what you want, then you are better off. If you didn’t know who your cousin was, then you couldn’t go to them in order to ask for help.
Of course, the downside of relatives is a bit the same. If a relative is a pain in the butt, and tends to drag you down, then you’d be better off without them. We “forget” them.
The good news is that, on average, having relatives has been a good thing. And thanks to another tool called marriage, we can increase our number of relatives by adding “-in-law” to their name. We do that because it tells us that the bond is through marriage, and may not be as strong as a more direct biological connection.
So the next time your relative calls you up and asks for a favor, think of it as an advantage, not a nuisance. At least do this a few times.
After that, read them the riot act. Let’s face it. They’re not going to change.
