When I studied genetics I learned that natural mutations were largely

environmental parameters can direct chromosomal changes so that they
are not random and that adaptation will occur and makes sense.
Without such demonstration, we are all asked to "believe" evolution.
I don't work in this field and may have missed such reports but I have
not seen them.
The mutations are largely randomly but selection is not. In other words
the building blocks with which evolution occurs is randomly formed, but
natural selection does not randomly select which blocks are used.
