I'm, uh, not literally saying that at all. No one kills humans for sustenance, and cattle do not have the same value as humans. The absurdity is in your PETA-fueled absolutism of giving all living beings an equal level of value. I'm going to eat a huge, expensive steak tonight just to cancel out the energy you've put into this conversation.

You stated, plain as day: > killing a non-endangered animal for sustenance is more acceptable than killing an endangered animal for a necklace pendant (or any other reason). Any other questions? Humans are non-endangered animals, are they not? Therefore you are _literally_ saying killing humans for sustenance is more acceptable than killing an endangered animal for a necklace.

Way to setup a [textbook] strawman argument so you could feel like you came out on top.

I'm on my way to Butcher's Table in Seattle btw, really looking forward to it! Thank you for encouraging me to indulge in excess tonight.

In the Science article they wrote, “Poaching resulted in strong selection that favored tusklessness amid a rapid population decline.” And, “Whole-genome scans implicated two candidate genes with known roles in mammalian tooth development (AMELX and MEP1a), including the formation of enamel, dentin, cementum, and the periodontium.” So, there was a change in the genes, but how do they connect this fact with poaching? I…

It's not like evolution detects this. If you kill off all the blond headed people in town, all the babies next year will be born with brown hair. The tuskless variant was already in the population at some proportion, but due to tusks being a target of poaching, those that carry the tuskless variant are more likely to survive and have offspring, who are also going to have this tuskless variant. Over time, the populati…

The blond hair allele is recessive and can be hidden. Two brown-haired parents can have a blond child.

Is this actually evolution or just selective breeding? By killing elephants with tusks the poachers are favoring elephants with the no-tusk gene. This isn't a lot different than killing a dog that bites sheep, which is how we bred herding dogs. Or a wolf that eats your baby, which is how we domesticated dogs. This trait already existed so it certainly wasn't "engineered due to mass poaching for ivory" as claimed.

Tuskless elephants probably due to hunting have a better chance of passing their genes.

Which makes it eligible for "Natural Selection"

What strawman? If anything, I am using reductio ad absurdum to show how your argument is asinine. You have yet to answer the question of why you think killing people is more acceptable than killing elephants. Or you could, you know, admit your statement is nonsense.

Listen. You're right. There, I gave you validation. But you're not going to change anyone's mind. So what's the point? Remember, the primary purpose of HN is entertainment (intellectual gratification). Internalizing this helped me break the habit of making such arguments "just to be right." I'll throw it back at you: Yes, I just ate two pork steaks. I have two more in the fridge. In fact, I'd personally murder a fami…

> In fact, I'd personally murder a family of pigs if it was the only way I'd ever be able to eat pork steaks again. They're that delicious, and I am that selfish.

> Life isn't nice. It's brutal, short, and sprinkled with periods of happiness and ecstasy. It's always been that way, and it'll be that way long after we're gone.

Then I assume you similarly have no issue with poaching, for all the same reasons?

This is such a weird to put eugenics. Say I kill all blue eyed people, would you then say "People are evolving brown eyes due to this guy" ?

It's not a consequence intended by ivory poachers.

Alright, eugenics wasn't the right word. But still this isn't evolution in the same way getting a medical intervention isn't. If you want to include everything we do as part of evolution, which is a defensible position, then all murders would be natural, this is not a practical perspective for a society.

For people who are not from the region but are criticizing poaching...maybe you should make sure your own house is clean before throwing stones at others. How many people critiquing this have industrial animal farms in their country, for example? And just to be clear: I don't mean that vile acts like poaching shouldn't be criticized, I more find the hypocrisy extremely grating, especially when it comes from meat eate…

I've been a vegetarian my whole life yet find this argument nonsensical. The animals being poached are in many cases on the verge of extinction, the animals raised on industrial farms are not. While I do find the idea of killing animals abhorrent the industrial process is significantly more humane than what happens to poached animals, which are typically left to slowly bleed to death or are permanently maimed.

> which are typically left to slowly bleed to death or are permanently maimed.

100% hacker news. 100% the lifestyle of HN

Live in a cage your whole life then get executed.

Or live 100% free, might die naturally, might be poached latter in life but are a pussy worried about bleeding out?

Obviously we execute many infants and children in the vegetarian livestock world. But they are males commonly, like in dairy and eggs. And again on HN dead male children don't count. Boko Haram massacres and sends to die in battle an order of magnitude more boys. And the Bacha bazi sex boys of Afghanistan.... don't talk about them.

Poaching feeds and educates a family for a year, you also get out and exercise poaching and take personal risk in a world of poverty which the West doesn't care about. Industrial farming feeds fat rich Americans more lazy food.

Poaching does ruin tourism so it does need to be fought. It costs poor people money, which in these communities is lives.

>our ancestors comprise mostly of females in a ratio roughly 3:2 to males. For anyone else wondering how this is possible on an individual level, apparently a lot of people used to reproduce with their first and second cousins.

I do not understand how mating with a 1st or 2nd cousin affects the ratio of females to males. Could you explain?

Assume that Bob knocks up both Alice and Eve.

Alice has a son, Eve has a daughter.

Alice's son knocks up Eve's daughter.

Their kid will have two biological grandmothers, but only one biological grandfather.

Apparently, historically, this type of thing was quite common and could heavily skew family trees towards the female side of things.
