evolution of human works
Explanation:
The cell theory states that all living forms are composed of cells. These cells are the basic structural units of all organisms and they evolved from pre-existing cells present in primitive living forms. From a biological point of view, the evolution of cells is similar to the evolution of human works, which were during the beginning of human civilization less specialized than in modern times. Likewise, somatic cells present in evolutionary recent multicellular organisms are capable of carrying out more complex functions than primitive cells present in unicellular organisms.
