Genes create the capacity to have thoughts.
But thoughts can be controlled and organized over time.
But organized based on experience in the world which the genes can't possibly know about since they arose in a completely different world from the artificial man-made modern world.
Why on the last part? We accept that the environment allows for other mutations to be selected for, why not a selection for Intelligence?
"Intelligence" is the product of many genes that must all work in harmony to create something with function.
If it is disrupted by a single mutation finding that gene would be easy.
First: Take everybody who scores over some arbitrary point on a test and find the gene they have that the people who score lower do not have.
Second: Demonstrate that this gene could effect intelligence in some way.
People have been trying to do this for a long time with ZERO results.
