My father got a brand new cow valve a few months ago. He had to choose between that, a pig one and a mechanical one, each one is better for each specific case from what I understand. But yeah, crazy stuff.

I imagine Muslims, Jews, and Hindus would tend to have specific preferences as well.

I'll speak to Jews. There is no such restriction or even preference.

Not only is this not a problem, Israel does a lot of research on creating pigs that are compatible with humans. Jews have no issue with pig heart valves. In general, the idea is that in Judaism human life is critical. You do what it takes to save lives. Only after that do the rules matter.

It's not weird at all. Biologically speaking, we are designed to eat meat. Our bodies produce all of the enzymes, such as protease and lipase, necessary for the breakdown and absorption of meat. The weird thing is how we developed sympathy and concern for such things. Human civilizations' current abundance of resources allows us the luxury to develop moral "philosophies" and become "vegetarians" effectively masking o…

Chasing an animal down, killing it, and eating it is in my opinion a significantly different activity than subjecting it to thirty likely-invasive procedures over the course of its life and then continuing to perform experiments on its dead body. Not saying it's more or less morally questionable, but significantly different. Evolutionary biology is overused as justification for human behavior. We were not "designed"…

>Evolutionary biology is overused as justification for human behavior.

Let me get one thing straight. I am not justifying anything. My angle is, what's the point? Don't justify anything at all. We're evil for killing, so be it. I am looking at it from a completely dispassionate angle. I do not need to somehow merge and mutate my moral framework to make it work with the existing reality.

>We were not "designed" to eat meat because we were not designed.

Ok we were "designed" by natural selection to eat meat. I am not making a theological argument.

> Chasing an animal down, killing it, and eating it is in my opinion a significantly different activity than subjecting it to thirty likely-invasive procedures over the course of its life and then continuing to perform experiments on its dead body.

In the wild, carnivores devour the flesh of their prey while it is alive and awake. Possibly more significant if not equal in being morally questionable.

>Other animals have also been shown to "befriend"/care for/grieve over animals of different species, so our own capacity to sympathize for animals should be no surprise.

No it is not. But what is surprising is that this empathy is the dominant behavior to our own evolutionary detriment (however mild). Empathy evolved to aid in survival of our genome, but when empathy evolves to the point where we are unable experiment on animals to assist in helping our own species... that is something unnatural.

A swiss army knife is designed to be used in many different ways. Just because you don't use all the ways doesn't mean it's not designed for it. You are an omnivore and you are designed to eat meat. Additionally, you are not designed to eat cellulose which is a huge component of what it means to be a herbivore. You are designed to eat meat, and designed to eat certain types of veggies. Who's to say that the veggie pa…

> Either way you ARE designed to eat veggies and MEAT, you can choose to eat veggies and deny half your nature, yes.. that is your choice. Is that similar to you only acknowledging being designed to eat meat and denying half of your nature?

No I acknowledge both. So how am I denying my nature. Just FYI, I have no skin in this game. Call me evil call me denying my own nature, I'm just looking at this all as if I was a psychopath (I'm not).

Weird how this is said without a shred of sympathy or concern for an intelligent, helpless creature. Weirder how it can be said without a sympathetic or concerned response. I hope we can someday move beyond seeing animals as a mere resource.

From what I heard, the pig lived a relativity good life. It was well cared for by the large animal veterinary school on campus. Had more space and better food than any factory raised pig. All experiments passed an ethics review. The pig was anesthetized before any procedure. The number of experiments may sound barbaric on the surface, but it was to reduce the overall number of pigs used in trials. Modern medicine wou…

Weird that these statements are made (and I don't mean by you, it's a trope to make them by people in general in discussions like this, I'm not picking you out) that it somehow justifies, or ameliorates, the awfulness of experimenting then dissecting (as someone said) a helpless intelligent creature.

I think these statements justify animal trials and using it to benefit humans definitely. But it doesn't justify or make better that it's still an awful thing to do to an animal and for the animal I think. It's weird right like where they get the blood of some sort of poor little sea creature that's got a blue copper containing blood it's just awful.

I really think we need to revise and reform a lot of how industry interacts with and especially commoditizes animals. I'm not saying we need to be vegans at all but I think there's so much room for improving how we talk think and act about this stuff. To make I guess what is probably an obvious point but I think the reasonableness of that point is not obvious but I think it can be a reasonable and obvious point without really attacking anybody and that non-threatening nature of that reasonable and obvious point I think is what is important about what I'm saying. It's possible. Less this comment be dismissed as some sort of low effort outrage--my heart's beating 50 beats a minute right now I'm not upset. I just think we can improve things there massively but that doesn't make anybody a monster.

You might be asking, why a pig? I don't know, but forever ago I wrote software for a cardiovascular imaging lab and pigs were their primary test subjects. I was like, "why pigs?" and the PI was like, "Imaging-wise, pig hearts aren't too different from humans. Plus, we can give them a heart attack in the scanner and not go to jail. Some labs use dogs. I just can't do that."

I was only recently acquainted with the idea that there are many people on the internet who become very angry that some people eat dog meat, but do not with say cow meat or pig meat. — I find this rather strange and do not understand this.

I think dog meat anger is mostly the result of Yulin Dog Meat Festival in China. [1]

It's completely unregulated and the animals (dogs, cats etc) would often be tortured and killed by amateurs because properly killing an animal is harder than it looks.

Dogs are also not eaten for meat or taste and mostly done for superstition.

Pigs are very anatomically similar to humans but due to being a food source there were probably also fewer ethical concerns compared to using primates.

It's really quite fascinating -- they aren't particularly close to us genetically, but because they're a similar sized mammal with an omnivore diet, you can teach their macro-biology from the same textbook.

Yep, back in high school we had a few days devoted to dissecting and documenting the anatomy of a fetal pig. It was really surprising how similar they actually were.

No, humans are omnivores, not carnivores. Our bodies are designed to function on a wide variety of food including fresh produce. To each their own, but consuming meat is a choice, not a necessity.

I already said this in a different comment, but the difference is that we were not designed while a Swiss army knife was. Design implies intent— it implies that something was developed for a purpose, that it's supposed to be used in a certain way.

Whether or not I use the corkscrew on my Swiss army knife doesn't change the fact that someone built the corkscrew for the purpose of opening corked bottles.

The enzymes/features humans possess that enable us to consume meat were selected for because at some point in the history of our species they enabled our ancestors to survive while others without the related genes did not.

This can change at any point, for any species. If we are no longer in an environment where eating meat confers a significant survival advantage then the fact that we evolved to be able to eat meat has absolutely no bearing on whether or not we should.

Why would you need to hook it up to the brain? I am assuming to respond to signals, for example stressed -> beat faster? But what would happen if you didn't have this automatic response? Let's say the heartbeat could be controlled by an algorithm or an app - for example if you lie down, it slows down automatically or if you expect to do some exercise, you can turn it up.

I'm fairly certain you don't want your heart controlled by an app on your phone.
