Do you ever wonder why we yawn when we are sleepy? Why do we crave for food, as we are hungry? Why do we feel insecure and scared when we are in total darkness? These behaviors are not unusual, as it may seem. But we didn’t think this simple human instinct has been passed on generations from our great ancestors when they started to roam the earth. How can it be passed on? In biology, memory is present if the state of a biological system depends on its past history in addition to present conditions. If this memory is recorded in the genetic material and stably inherited through cell division (mitosis or meiosis), it is genetic. This genetic memory is inherited in our DNA by survival means. Why? DNA is the only storage medium involved in the transfer of information to the next generation. There is a saying about survival of the fittest. It’s true, where human evolution apparently prepared our species to become possibly the best and clever living being able to adapt to different challenge
