I don't know if this is the right NG for this question, but
has it been guesstimated which sense developed first?
I would think it would be taste or touch. If one of the tiny
early organisms could detect the molecules that nourished it,
it would have a greater advantage than being able to feel when
it runs into something.
But, do we have to take into account a primitive nervous
system to electrically react to the sense, or would a reflex
response, without a brain, qualify as well? A reaction to it's
environment without a brain.
I suppose in order to 'react' it would need some form of
nervous system, brain or not.
A Venus Fly Trap has a nervous system reaction based on touch,
yet has no 'brain'. Is that considered a sense of touch?
It's like the chicken and the egg. Which came first, senses or
a brain, if you do indeed need a brain to call it a sense...
Anyone have and ideas?
