摘要

In 1859, Charles Darwin published the theory of evolution. It is based on the assumption that an organism's properties are hereditary, however, random changes occur in it. Successful changes that increase the chances of survival of the given organism are carried forward into future generations. Once the scientific community could understand the Darwin's concept, some new questions arose: what, exactly is being transferred over generations? Where do the random changes occur? And how can they manifest themselves in a living organism ?
