Diferencia entre revisiones de «Ernst Mayr»

Mayr defendió que, a diferencia de la física, la biología no se fundamental tanto en leyes como en conceptos:

{{Cita|If one concludes that there are no natural laws in evolutionary biology, one must ask, on what can one then base biological theories? The view now widely adopted is that theories in evolutionary biology are based on concepts rather than laws, and this branch of science certainly has abundant concepts on which to base theories. Let me just mention such concepts as natural selection, struggle for existence, competition, biopopulation, adaptation, reproductive success, female choice, and male dominance. [...] As a result, a philosophy of physics based on natural laws turns out to be something very different from a philosophy of biology based on concepts.|Mayr 2001<ref>[http://www.aps-pub.com/proceedings/1454/409.pdf The philosophical foundations of Darwinism] ''Proceedings of the American Philosophical Society'' 145:488-495</ref>}}
