DEBATE There evolutionary evidence that snakes once had legs and by not using, they atrophied? Charles Darwin (1809-1882) - Watercolour painted by Charles Darwin Georgr Richmond in the late 1830s. Source: GNU Free Doc License, www.wikipedia.org We can not discuss evolution without mentioning Charles Darwin. The theory that explains the evolution of living beings by natural selection was proposed 50 years after Lamarck's theory. Do you know name a few differences between the theories of Lamarck and Darwin? Not? So let us help you in this differentiation. The three following aspects will be considered to establish a comparison for the two theories. The fact of evolution: the world is evolving or static? Both Lamarck as Darwin believed in the world of evolution, however, Lamarck was the first researcher who proposed a solid theory about evolutionary change. The mechanism of evolution: the effect of use and disuse was accepted by two scientists, though with less intensity in the ideas of Darwin. A primary concern for diversity or the adaptation: here there is a fundamental difference between Lamarck and Darwin. For Darwin, the adaptation of living beings is the product of natural selection. For Lamarck, the adaptation was the final product of physiological processes required by the needs of organizations to transform their environment (Mayr, ACTIVITY And now, before these differences presented between Lamarck and Darwin, you will be able to answer the question of why snakes crawl? If not, then let's go back to the example of the giraffe's neck to explain the ideas of Darwin. In his book "The Origin of Species," Darwin expressed general ideas about the theory of evolution of species. Darwin proposed that only the fittest and strongest survive, and nature itself is responsible for Natural Selection.

DEBATA Postoje dokazi da je evolucijski zmije nekada imao noge i ne koristi, što odumire? Charles Darwin (1809-1882) - Akvarel naslikao Charles Darwin Georgr Richmondu u kasnim 1830-ih. Izvor: GNU Free License Doc, www.wikipedia.org Ne možemo raspravljati o evoluciji bez spominjanja Charlesa Darwina. Teorija koja objašnjava evoluciju živih bića prirodnim odabirom je predloženo 50 godina nakon Lamarck teorije. Znate li ime nekoliko razlika između teorije Lamarck i Darwin? Pa neka nam pomoći u ovom diferencijacije. U sljedeća tri aspekta smatrat će se uspostaviti usporedbu za dvije teorije. Činjenica evolucije: Svijet se razvija ili statična? Oba Lamarck kao Darwin je vjerovao u svijetu evolucije, međutim, Lamarck je bio prvi istraživač koji je predložio čvrste teorije o evolucijske promjene. Mehanizam evolucije: učinak korištenja i zapušteno je prihvaćen od strane dva znanstvenika, iako s manjim intenzitetom u idejama Darwina. Primarna briga za raznolikosti ili rekonstrukcijom: ovdje postoji temeljna razlika između Lamarck i Darwin. Za Darwina, prilagodba živih bića je proizvod prirodne selekcije. Za Lamarck, adaptacija je konačni proizvod fizioloških procesa potrebnih za potrebe organizacije transformirati svoju okolinu (Mayr, AKTIVNOST A sada, prije nego što ta razlika između prezentiranih Lamarck i Darwin, od vas će biti u mogućnosti odgovoriti na pitanje zašto zmije puzati? Ako ne, onda idemo natrag na primjeru žirafa vrat objasniti ideje Darwina. U svojoj knjizi "Porijeklo vrsta" Darwin je izrazio opće ideje o teoriji evolucije vrsta. Darwin je predložio da samo najspremniji i najjači preživljavaju, a priroda sama je odgovorna za prirodnim odabirom.
