I think that counts as two toppings.
"Natural selection is not evolution" is actually correct. Evolution is the observed fact that species change over time. The fact that evolution has occurred is not really open to debate, unless you're prepared to entertain loony notions like "God put those fossils there to test our faith."
Natural selection is the mechanism that Darwin proposed to explain why/how evolution happens.
An AK-47 receiver made out of a rusty shovel:
Perhaps the problem is that the receiver is the legally-controlled part of the gun. Everything else is spare parts. Making receivers is easy now.
I'm no expert, but it seems to me that making a barrel is the hardest part. Why isn't the barrel the controlled part?
Sure, I can hide the origin so it's not obvious where the money came from. So, if I'm a high-school chemistry teacher, and I used this bit-coin trick to "launder" the millions of dollars I made selling meth, then can I just go out and buy a mansion and fleet of Lamborghinis, and expect to stay out of jail? I think not...
Perhaps I just don't understand what "money laundering" means, but I don't really see how bit-coin is of any use whatsoever for money laundering.
Money-laundering, as I understand it, means to disguise the true origin of ill-gotten funds, so as to make the income appear legitimate.
I think there's confusion in the two different means of the word "disguise". In one sense, it means simply to hide or obscure. In another sense, it means to make something or someone appear to be something else.
Bank robbers wear a disguise in the first sense. A bank-robber doesn't wear a Richard Nixon mask because he wants people to think Richard Nixon robbed the bank. He just doesn't want to be identified in a line-up. This is the same kind of disguise that bit-coin offers. And even in that, it doesn't really stand up.
But I think people interested in money-laundering are using the other sense of the word: they want to be able to actually spend their ill-gotten gains without arousing suspicion. They need to make it look like legitimate income. That is why Walter White bought a car-wash.
Merely obscuring the true origin of your money is useless. If the government is even a tiny bit curious about the true origin of your money, you're already well and truly fucked, whether or not they can ever figure it out.
Your joke is too subtle without a reference.
In another sense, China is a province of Taiwan. It just happens to be under the control of a band of rebels at present.
There are no La Brea Tar Pits in Scotland!!
So, in Iceland accidentally sleeping with your cousin in a very real danger. That explains some things... like Bjork.
And you'll keep on researching it, until you give us the answer we want.
I don't know much about gun technology, so maybe somebody can explain why the lower receiver is the controlled part. Why not the barrel? It seems to me that the barrel is the heart and soul of a gun. You can make a gun with just a barrel and nothing else: it's called a cannon.
Furthermore, I would think the barrel would be the hardest part to manufacture, given the forces and temperatures it must endure, and having to be perfectly straight, and rifled. I would imagine that 3-D printed barrels are probably a long, long way off.
3-D printed receivers are already here, and only going to get better and cheaper. If they don't change the regulatory framework to start controlling the rest of the parts, then soon anyone that wants to will be able to make a gun at home and all the gun control laws in the world will just be so much pissing in the wind.
