These laws were initially very controversial . When Mendel's theories were integrated with the Boveri--Sutton chromosome theory of inheritance by Thomas Hunt Morgan in 1915, they became the core of classical genetics . Ronald Fisher later combined these ideas with the theory of natural selection in his 1930 book The Genetical Theory of Natural Selection, putting evolution onto a mathematical footing and forming the basis for population genetics and the modern evolutionary synthesis . </P>
