Our DNA is hardwired into each cell in our bodies but it makes use of an epigenetic memory that can modify how a gene works. This memory is like computer cookies. They get dropped by websites to remember important information when you return. DNA cookies get set by our environment and can be passed onto future generations. As our cells learn things that increase the chances of survival they remember this information in real-time via epigenetics. We are amazing creatures.
