Presumably they do when they are presented with a corpse...
I believe that the emphasis is on the word "presumably" in that statement....because supposition was all I heard in that video.
Who really knows what is going on in an elephant's mind? David Attinborough was 'interpreting' what he saw in this behavior and likening it to human behavior....does he know any of it is true? Like all evolutionists, he is athletic when it comes to jumping to pre-conceived conclusions.
Who knows what signals are being processed by the smell of the dead elephant? As I mentioned, some in the animal kingdom are designed to live in troupes or close family units, making the loss of a member felt by the entire family. Behaviors can be misinterpreted, especially when there is an agenda to uphold.
With all due respect - there is no way you can possibly know that.
With all due respect...neither can you. Neither can anyone.....except their Maker.
I'm guessing that dogs don't plan their next vacation or discuss what they would like to have for dinner this evening...but we don't know that they have no concept of the future at all. Obviously it would not be the same - probably not even very much like - a human's concept of the future - but we don't know that they don't have one at all and it is quite difficult to imagine how animals could function if they were completely directed by instinct 'in the moment' - there would be no direction to their actions at all save momentary responses to momentary stimuli. I can't see that as a very good survival strategy.
As you are aware, the Bible indicates that fear of man was instilled in animals when humans were first given permission to eat flesh. If man was given this permission, then perhaps some animals were given the same kind of permission. Why instill a fear of man or even a fear of one another? To give animals a "fight or flight" response in any given situation. It is a survival mechanism so that hunters have to work for their food. Herbivores who have no need to hunt or kill, still have self-protective instincts so that they are not so vulnerable to predators.
There is no proof that animals have a capacity to consciously plan the future. Instinct forces them to do what is necessary to preserve their species. Storing food for winter is not a conscious endeavor in them....it is in us for obvious reasons.
No - it is the result of the brains sub-cortical structure and activity in response to the loss/departure of another animal that was closely related in some way (family, friend, partner) - these regions of the brain and the associated neurochemical responses are not just 'analogous' but 'homologous' throughout the mammalian class. It is the outward behavioral expressions that differ between species - not the reason for the 'grief' response.
"The mammalian class"...ah yes, the lumping of all mammals into one group as if they are all somehow related in an evolutionary chain. Blah, blah, blah....yes, scientists have all kinds of explanations for what they want to believe, just as Bible believers do. However, none of us have any solid evidence for what we believe, even though we will each say we do.
If you want to see animals grieving as if that somehow points to shared human traits because of an imagined relationship to apes or any other creature, then go for it. I personally see the human race as a separate and uniquely different class of creature, made by the same entity as all other creation, but with qualities and abilities that no other earthly creation possesses. I even see that we are all made of basically the same raw materials....but it doesn't mean that evolution took place, even though science wishes to interpret the "evidence" that way. We will all know soon enough I guess.
