The biological species concept defines a species in terms of biological factors such as reproduction , taking into account ecology, geography, and life history; it remains an important and useful idea in biology, particularly for animal ...
Ernst Mayr defined a species as a population or group of populations whose members have the potential to interbreed naturally with one another to produce viable, fertile offspring. (The members of a species cannot produce viable, fertile offspring with members of other species). [ 69 ]
They were able to produce statistical models of population genetics that included Darwin's concept of natural selection as the driving force of evolution. [44] Developments in genetics persuaded field naturalists such as Bernhard Rensch and Ernst Mayr to abandon neo-Lamarckian ideas about evolution in the early 1930s. [45]
