   What is Weismann's theory of variation?

   • Additionally, Weismann elaborates a theory for variation within a group of related organisms, claiming that variations in germ-plasm cause those groups to evolve. He hypothesizes two causes of variations, the first relies on environmental factors, such as nutrients, the second on the multiplication of determinants.
