Poor fetus
left all alone with people insisting.... wait a second, what are you guys even trying to say?
First things first, "animals" work in much the same way we do *gasp*, we are related to them all afterall, most of the basics are the same.
Even in "lesser" animals the instincts telling them to do things aren't as simple as you guys are making out. What instincts do is send a message to the individual, which the individual then interpretts into its own "mind language". This is the same for every organism, even humans, even plants.
There is one message every living thing gets, and that is "try to pass on your genetic material", different animals then interprett that in different ways, suited to their species.
Some mind languages might be more complex, but the instincts are the same and the result is the same. The complex preparation of our instincts makes us think we are making big decisions, when really we are just going to complex lengths to get our instinctive tasks completed.
Forget about the "lymbic" system, it really is irrelevent. Its just what makes us feel like we do, other organisms would get their own rewards in their own way that they happened to evolve instead of the lymbic system.
As fetus said "how do you know a jellyfish doesn't feel good about spwning?" and I bet it would in its own little way.
I bet salmon feel as sweet as plumb after swimming miles up stream to their spawning ground. Thats just how it worked, if animals could be spoonfed instincts the way you seem to think then it never would have needed to change, we'd just hear the message in our heads and say "yes sir!". But we don't, because instincts don't work like that, the instinct needs to be transformed into an idea by the brain before it can be acted upon, and for animals without brains, it needs to be done in some other way.
There is no "animals do this, humans do that", you'll find that if all animals work in some way, then humans inevitably do too. Not saying humans aren't unique, just saying all animals are unique and anything shared by all those unique animals will be shared by us too.
Not all animals would feel pleasure in the sense we feel it, thats just anotomical semantics, the fact remains that all organisms breed to reproduce, but none of them realise that, crocodiles think they do it to spend a romantic evening nibbling on the hottest croc tail in the district, fish get mad thrills dropping wads on unfertilised egg batches, preying mantis' want it bad enough to risk their lives, its just too sweet to not go for it, none of these feelings are exclusive to humans, the words our brains put to them are strictly human but the original urges that we needed to subconsciously translate are not.
So, yeah humans have sex for pleasure, gee lets call the newspaper
but the pleasure is only there to make reproduction happen.
Everyone really should know this
What is the alternative you had in your minds? The reproduction is there to make future generations of pleasure happen? LOL
