I am interested in learning as a process of knowledge acquisition. The first requirement for learning is a place for knowledge storing and the ability to transfer this knowledge. Information storage is called memory. Memory for most of us means storage room for information. Memory is associated with brain, computer memory, hard drive, flash cards, memory stick… I also remember old-fashioned books and another written material. However, the oldest, the most efficient, the most widespread method of information storing is the DNA molecule.
The DNA molecule contains genes that have more information about humans than a human can learn in his life. Those molecules can effectively transfer information. Moreover they can learn. They change, storing information corresponding to the changing environment.
