Do Animals Have Types?

"I wonder if what makes humans so successful and adaptable is that we have functions instead of instincts. We need food and sex and so forth, but we lack more complex drives like "fly to Canada during the summer" or "steal birds' eggs". People do have complex drives, but they appear to vary from person to person."

If I understand what you're saying, I don't think this is necessarily true. These "drives" are rather abstract, and I doubt animals would process them in the same way. That is, it wouldn't be "fly to Canada during the summer", but "it's getting warm, and I better fly up north", and it wouldn't be "steal bird's eggs", but "I'm hungry/it's time to eat, and I smell/see/whatever something which will do". Of course, this is still rather abstract but I think it communicates what's going on better. I think we can find similarities in humans, especially since we don't actually have to first process things abstractly to do them. Earlier it was raining, and I saw some people running towards their home. We could do this with just about anything, abstracting and simplifying (or showing reality better). (Also, regarding knowing if it's summer or not, I think there may some "biological clock" correlating some conditions (food, warmth, something else). If you have meals at certain times of day, eventually you'll be able to know the time of day without having to check of clock; maybe something similar is going on.)

I'm thinking that the most primal pairings -has been there since reptile animals- are Se/Ni and Te/Fi. Ne/Si and Fe/Ti comes up later to aid the survival of most mammals (and birds?). In order, I'd imagine that'd be like...

1. Se/Ni --> the most primal, without a sense of self, just cellular organism evolving... Very instinctive and primal.
2. Te/Fi --> appeared since fishes, mollusks, amphibians, reptiles..
3. Fe/Ti --> this is for social cooperation, I think it started since mammals. How did this happen? Idk, maybe our T/F make-up got mutated and turned into different dirrection (Fe-Ti) somehow.. You can also see bugs doing this kind of social cooperation, but they don't relate to our evolutionary path, yes? I'd say they have some similar mechanism as Fe/Ti, but evolved differently.
4. Ne/Si --> this starts to appear since apes? or big mammals? Seems like they start to find alternatives in dealing with the same object (the use of hands and language?).

I think it's possible that variation in oscillation pairings is just a matter of adjustment in the strength of N and S in Pe/Pi (in bigger sense of species, not necessarily of individual self). And I'm not saying that Ne/Si is the most advanced form of cognitive operation, if any, it's the newest born function, thus less developed. Se/Ni has gone through most of the eras, and still survive until now, so it makes sense to say they have advanced greater. Both are useful, that's why they still exist today.

This is interesting!!
