Not that simple. Brown bears and polar bears produce fertile offspring, as do bison and cattle, and the false killer whale with a bottlenose dolphin. (Far from an exhaustive list)
It's generally a useful definition but it isn't a "rule".
Canis familiaris is a subspecies of C. lupus as of 2005. There is a push to distinguish it as a distinct species but that is not the current consensus.
"Testing" for speciation is pretty silly, tbh, because it's an arbitrary distinction no matter what. Our placement of rigid definitions onto the constant gradual process of evolution is always going to have edge cases and outliers. So we give things useful labels and move on until we have better tools (DNA analysis has been great) or have need of better definitions.
Does dogs being wolves do anything for the general public? No, but that's what common names are for. Does the distinction of Canis lupus familiaris help scientists right now? Probably. If not there'd be a stronger push to change it.
And then three people say to the fourth, "stop driving your car through this garden" and there aren't laws or courts to handle the dispute so instead they use violence or intimidation.
That's an over-simplification. Marx's stateless society was a prediction of the natural outcome of a post-capitalist world and is probably the most utopian aspiration of the philosophy.
Communism does not mean "no government". You need a government. Or rather, whatever system of decision-making and distribution emerges is the government. Any form of cooperation and collective agreement is government. Don't tell the anarchists, they won't get it.
It doesn't have to be heirarchal in the same way but ultimately if you live in a society then at some point someone is going to tell you what to do.
Republicans are currently making it harder for left-leaning populations to vote, by closing polling stations in urban areas or opposing vote-by-mail. Automatic voter registration is being actively resisted. That is "why".
Voter registration became a thing in the 1800s to limit the voice of immigrants, adopted state by state.
Oregon first, and about a dozen other states since, have made registration automatic when you get a driver's license or state ID.
I'm fully in favor of tiered and more rigorous licensing. Basic license should only clear you to drive a small, low-power sedan/wagon/hatchback. Vast majority of people won't ever need more than that.
I worked at GameStop when Farmville was big. Regularly had older women come in and spend $40 to $100 dollars on Farmville cards. A couple of these women came in every week, outspending almost every "traditional" gamer I knew.
Changing spellings to match pronunciation should happen more often, to ne honest. And I don't think UK or Australian English get to throw any stones about shortening words and phrases, the US isn't calling anything "spag bol".
Ironically, US English is in many ways more traditional than UK English. The US uses many words and phrases that used to be common to both continents but later changed in the UK.
US did try to de-French most spellings with mixed success.
Of course it is, Nintendo doesn't know how to properly integrate multi-player. Especially online. Sometimes they accidentally do an okay job, and there was a while where the handheld consoles did some cool stuff but some perverts on Pictochat scared them so bad you can't even talk to your friends in Smash Bros.
That's how Musk names everything. He loves the letter X, he named the Tesla models "S", "3", "X", and "Y", the Cybertruck, his five most recent children including "Techno Mechanicus"... He's absolutely unfit to be in charge of anything.
