Slow-vine (Leptophis ahaetulla). This snake well known in the Atlantic, has arboreal habits and feeds on small insects and lizards. His behavior is apparently aggressive, opening his mouth widely when intimidated, but it is not poisonous. Source: Photo courtesy of Prof..

The problem of adaptation and evolution of species in their habitat has been the subject of much discussion until the nineteenth century. At that time, studies on the classification of living things, made by Lamarck, sought to explain that living beings are "transformed" by his own efforts, in the face of environmental changes. Consider the classic example of giraffes didactically used for many years in an attempt to model the evolution of species based on the ideas of Lamarck. The current giraffes feed on the leaves of the tree canopy. Her long neck facilitates the collection of that food, in the rainy season. If the giraffes were not "pescoçudas", they would be alive today? Do they always had the long neck? Giraffes Zoo Curitiba. Giraffe is the common name given to the species Giraffa camelopardalis, or camel leopard, as they were called by the Romans when they existed in North Africa. Are ungulates with an even number of toes. Source: Photo courtesy Danislei Bertoni. Take for basic studies presented by naturalist Lamarck, in the nineteenth century, in his Philosophie Zoologique. On the continuity of the fundamental characteristics of the various types of animals, Lamarck said that the frequent use of any organ develops and increases, while its permanent disuse weakens until no longer appear in future generations. Thus, by the use or disuse, a feature can be transmitted or not to offspring reproduction. Lamarck exemplifies the appearance of the skin at the base of the fingers of birds, terrestrial originally from the continued use by swimming in search of food. The skin between the toes grow due to the increased flow of blood through the muscle movements performed (Storer, 1979). SEARCH In texts, books, magazines provided by the teacher, research on the eating habits of the giraffe and analyze if the neck has influence in this process.

Slow-vino (Leptophis ahaetulla). Ova zmija poznata u Atlantiku, ima drvni navike, a hrani se malim kukcima i gušteri. Njegovo ponašanje je očito agresivna, otvarajući usta široko kada je zastrašivao, ali to nije otrovan. Izvor: Foto ljubaznošću prof. Franjo Asiški da Silva Roberto, prof.

Problem prilagodbe i evolucije vrste u njihovom staništu je bio predmet brojnih rasprava sve do devetnaestog stoljeća. U to vrijeme, studije o klasifikaciji živih bića, od strane Lamarck, nastojao objasniti da su živa bića "pretvara" vlastitim naporima, u lice promjena u okolišu. Razmislite klasičan primjer žirafe didaktički koriste dugi niz godina u pokušaju da se model evoluciju vrsta temelji na idejama Lamarck. Aktualni žirafe hrane na lišću krošnje stabla. Njezin dugi vrat olakšava prikupljanje tu hranu, u kišnoj sezoni. Ako su žirafe nisu bili "pescoçudas", oni bi danas bila živa? Da li je uvijek imao dugačak vrat? Žirafe Zoološki vrt Curitiba. Žirafa je zajednički naziv za vrste Giraffa Žirafa, deva ili leoparda, jer su se zvali Rimljani kada su postojala u sjevernoj Africi. Jeste papkara s paran broj prstiju. Izvor: Foto ljubaznošću Danislei Bertoni. Uzmi za osnovne studije predstavljene od strane prirodoslovac Lamarck, u devetnaestom stoljeću, u svom Philosophie Zoologique. Na kontinuitetu od temeljnih karakteristika različitih vrsta životinja, Lamarck je rekao da često korištenje bilo kojem tijelu razvija i raste, dok je njegov stalni zapušteno slabi dok se više neće pojavljivati u budućim generacijama. Dakle, uporabom ili zapušteno, značajka može se prenijeti na potomstvo ili ne reprodukciju. Lamarck ilustrira izgled kože na bazi prste ptica, kopnenih podrijetlom iz daljnje uporabe od strane kupanje u potrazi za hranom. Koža između prstiju rastu zbog povećanog protoka krvi kroz mišić kretanja izvode (Storer, 1979).
