Short answer: Yes. Humans are held to the same rules as any other living organism.
But you have forgotten that we are talking about changes over generations, not simple years.
We can easily see behavioral changes in our real time. Like babies being able to recognize cell phones as cameras, or boxes that hold little grandparents in them. The internet is full of cute videos of babies trying to swipe hard copy magazines like they would a tablet, or reading number flash cards and calling 11 "pause".
The physiological changes will take time to appear.
