It is very difficult to prove if sensation came before intuition in our species. However, I think it can be proven if you look at the history of life itself.
Sorry to re-hash but it's a common misconception. Evolution will not change/improve a trait if its current performance does not disadvantage individuals. It requires outside pressure to make up something new. You could assume a mutant version of things spread, but that would be quite the lucky trick.
Dichotomies could have come about from only certain types of neural wiring being viable/efficient enough.
You could assume Intuition came about to deal with more abstract problems, but...
Actually, have you heard of
persistence hunting? One example is running down antilopes in the Kalahari desert. A description of the practice (in
a running book's book) mentions that the combination of moving at high speeds and monitoring the ground to track the animal induced a trance-like state of non-thinking awareness and strong empathy with the animal (better deducing how it would have reacted at points.)
The above could have enhanced strong Sensing. Not sure what to think.
What parts of life's history would you use? Our knowledge of it is pretty incomplete.
