When the baby calves are born they instinctly knows who their mother is...
As to your analogy with animals not caring for other animals or showing emotional attachments to their own kind, here is my rendition. When we see a thief or a criminal getting slained by the authorities, do we show emotional attachments for them?
If the first thing an incubated baby chick hatches and sees a human, that chick will believe that human is its parent. If you separate a baby monkey as soon as it is born and place it in care of humans, that baby monkey will look at the human(s) as the parent. And your point is? We are talking about self-awareness and the understanding of life and death. Like I said, if animals were fully self-aware and understood life and death as the way humans do, that baby monkey and chick would look at a human and think "You're not my mommy!", squirrels would open up acorn banks and white-tailed deer would have a calendar and note that hunting season is coming up and they need to get the fukk out of public hunting grounds until post-season. I didn't say animals are stupid - a squirrel can recall where it hides 100 nuts when the snow melts and I can barely recall what I had for dinner last night. But a squirrel sure as hell won't be able to read what I'm writing here.
And your story of human emotions just proves my point further - humans (once they become a certain age) are fully self-aware, understands life and death, and displays all of the emotions that we humans show. The fact that we cry tears when something bad happens, does not mean that a rabbit or a cow that has tears on its eyes means it is crying the same way humans do. There is a term for that and it is anthropromorph
ism - depicting inanimate and/or supernatural objects (like God) or animals to display human attributes and behavior. Usually, anthropromorph
ism is used to subjectively skew a topic as a prejorative (example: "Why do you guys eat meat?! Don't you know they cry and have feelings just like you and I?).
So you were a bull and that's how you know this?
Like I said, you shoot a wild boar dead in its track, 20 other boars run away. Wait 10 minutes, all 20 come back and start eating roots RIGHT BESIDE THEIR DEAD PAL YOU JUST SHOT. Shoot another boar dead, they run away. Wait 10 minutes, THEY ALL COME BACK OUT AND START EATING AGAIN RIGHT NEXT TO THEIR DEAD PALS. If animals understood life and death like humans, they would all start crying after their pal is shot and they would all run away from the hunter. It doesn't take a rock scientist to realize that humans are wired way differently from animals. With the exception of a few monkey species, the great apes, and dolphins, all other animals have near-zero self-awareness and doesn't understand life vs death. I didn't say intelligence here. We are talking self-awareness and (the possible) understanding of life and death.
to really know is to go to the slaughter house (long cheng)...the animals knows exactly what they are about to face, often crying and trying to escape when ushered to the kill pen.
They try to escape because that's what all animals respond to something (like a human) caging them, pushing them, and chasing them. A chicken is not going to jump on your knife for you even though it has been domesticated for thousands of years. All animals with an eyeball (as well as humans) has moisture-producing glands otherwise, they would all go blind when the eyeball dries out or gets dust on it. Just because the moisture comes out doesn't mean it is crying just like a human does.
Obviously, you all have a problem with the scientific method.
