Someone on here recommended a book called "Wetware: A Computer in Every Living Cell" and it goes into detail but at a fairly layman level explaining how stuff like this works at the biochemical level. Basically we have genes that code for pieces of proteins and those pieces can be combined in millions of different ways to form unique proteins. Feedback systems based on proteins turn individual genes on and off to encourage the production of effective proteins. Essentially we have the ability to evolve and adapt at the protein level without any modifications to our genes. Honestly reading that book really opened my eyes to how complex this stuff really is. Biology is unbelievably robust and flexible well beyond the basic model of evolution that we are taught takes places at the genetic level.
