The author recognized that “the theory of evolution is indispensable to an explanation of the interesting facts of myrmecophily and termitophily” (Wasmann 1910, p. 340). This work was considered by Haeckel as a “masterpiece of Jesuitical sophistry” (cited by Richards 2008, p. 360) and actually sparked his very last public lectures in ...In biology, evolution is the change in heritable characteristics of biological populations over successive generations. Evolution occurs when evolutionary processes such as natural selection (including sexual selection) and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations.When you buy a certificate of deposit, you lend a bank or investment firm a sum of money for a period of time in exchange for interest payments.

The ‘theory’ of evolution is most often used not so much to refer to a scientific theory at all, but rather to a set of very general propositions.
