Biology Returning to the example of the giraffe's neck, and studying the ideas of Lamarck, a possible explanation is that several giraffes with short necks would be set in an environment where the best buds and leaves were high in the trees. With the need to get the higher leaves, these giraffes stretched their necks constantly. Thus, over time, their offspring would be born with longer necks and this happened every generation to reach stability, ie, the result would be the giraffe we know today. DEBATE Does Lamarck was correct in its conclusions? There is possibility of some acquired characteristic to be passed on to offspring? Justify. The idea proposed by Lamarck transformismo, still indicates that living things can be in constant evolution. Lamarck in his studies, went further, concluding that the changes occurring in the species in response to an imposition of means, would be transmitted to their offspring. Remember that until then, at the time of Lamarck, the knowledge produced on the role of genetics in the transmission of traits from generation to generation was insufficient for any researcher to pursue and advance in their studies, because the foundations of genetics would only born in 1822, with Gregor Mendel. Therefore, Lamarck had no knowledge that would enable developing their research. Jean-Baptiste Pierre Antoine de Monet, Chevalier de Lamarck (Bazentin, 1744 - Paris, 1829). French naturalist of the nineteenth century, it was he who introduced the term Biology and developed the theory of acquired characteristics, a theory of evolution has overcome. Lamark personified pre-Darwinian ideas about evolution.

Did you know that ... Snakes constantly stretch your body to be able to pass through narrow spaces in their habitats. By going through these tight spaces, the legs would not be used. If they had long legs, these would hinder their walking on the grass and if they had four legs, could not move. Although reptiles have legs, snakes do not have, however, under the laws of Lamarck, at some time they had them but lost them. So it seems, according to Lamarck a cause of evolutionary change was the ability to respond to special conditions of the environment The snakes crawl why not have legs or they do not have legs for crawling?

Biologija Povrat na primjer žirafa vrat, i proučavanje ideje Lamarck, moguće objašnjenje je da je nekoliko žirafe s kratkim vratom će biti postavljena u okruženju u kojem su najbolji prijatelji i listovi su bili visoko u krošnjama drveća. Uz potrebu dobiti višu lišće, te žirafe pružio vratove stalno. Dakle, tijekom vremena, njihovi potomci će biti rođen sa dužim vratovima i to se dogodilo svakoj generaciji do stabilnost, odnosno, rezultat će biti žirafa danas znamo. DEBATA Lamarck je li točna u svojim zaključcima? Postoji mogućnost da neke stečene osobine se prenose na potomstvo? Opravdati. Ideja je predložila Lamarck transformismo, još uvijek ukazuje da živa bića mogu biti u stalnom razvoju. Lamarck je u svojim istraživanjima, otišao dalje, zaključivši da su promjene koje se događaju u vrsta kao odgovor na izricanje sredstvima, će se prenijeti na svoje potomstvo. Sjetite se da do tada, u vrijeme Lamarck, poznavanje proizvedene o ulozi genetike u prijenosu osobina s generacije na generaciju bilo nedovoljno za bilo istraživač nastaviti i napredovati u svojim studijama, jer temelji genetike bi samo rođeni u 1822, s Gregor Mendel. Stoga, Lamarck nije imao znanja koja će omogućiti razvoj svoje istraživanje. Jean-Baptiste Pierre Antoine de Monet, Chevalier de Lamarck (Bazentin, 1744 - Pariz, 1829). Francuski biolog iz devetnaestog stoljeća, on je bio taj koji je uveo pojam biologije i razvio teoriju stečenih karakteristika, teorija evolucije je prevlada. Lamark personificira pre-Darwinovu ideje o evoluciji. Izvor: GNU Free License Doc, www.wikipedia.org DEBATA Što o zmijama, je da ova životinja može razviti noge u vašem tijelu u budućim generacijama, ili su imali noge i završio ih izgubiti? Jeste li znali da ... Zmije stalno se protežu svoje tijelo da bi mogli proći kroz uske prostore u njihovim staništima. By prolazi kroz ove uske prostore, noge neće koristiti. Ako su imali duge noge, to bi spriječilo njihovo hodanje po travi, a ako su imali četiri noge, nije mogla pomaknuti. Iako reptili imaju noge, zmije ne moraju, međutim, prema zakonima Lamarck, na neko vrijeme su ih imali, ali ih je izgubio. Dakle, čini se, prema Lamarck je uzrok evolucijske promjene je sposobnost da reagira na posebnim uvjetima u okolišu Zmije puzati zašto ne imati noge ili nemaju noge za puzanje?
