Darwin’s theory is based around the idea of a common ancestor that all living organisms can be traced back to. . This ancestor is called the Last Universal Common Ancestor or LUCA. . Neoplasia. is a process of “new growth” in which normal cells undergo irreversible genetic changes, which render them unresponsive to ordinary controls on growth exerted from within the “transformed” cell or by surrounding “normal” cells..
