As a neurobiologist, do you think hand can be evolved without the sense of touch in the brain? Isn't this an evidence for irreducible complexity?

There is certainly a plan behind this perfection. We cannot consider this extremely complicated mechanism separately, in which the brain is the main feature. The hand is just a means by which we can carry out motor activities, but everything is linked to an indissoluble plan. Without the presence of a higher project all the mechanistic aspects do not make any point. We can think that there is a code that pre-exists practical implementation. The code cannot be secondary compared to the elements arising from the project itself. Thanks to these elements, the code is simply a synthesis of all the mechanisms of interaction that allow the creation of those elements that can put the project into practice.
