CO OZNACZA SŁOWO NATURAL SELECTION
Naturalna selekcja
Selekcja naturalna jest stopniowym procesem, w wyniku którego cechy biologiczne stają się mniej lub bardziej powszechne w populacji w zależności od wpływu odziedziczonych cech na różnicowy sukces reprodukcyjny organizmów oddziałujących ze swoim środowiskiem. Jest to kluczowy mechanizm ewolucji. Określenie "dobór naturalny" zostało spopularyzowane przez Charlesa Darwina, który zamierzał go porównać z sztucznym selekcjonerem, teraz bardziej określanym jako selektywna hodowla. Odchylenie występuje we wszystkich populacjach organizmów. Dzieje się tak częściowo dlatego, że w genomie pojedynczego organizmu występują przypadkowe mutacje, a mutacje te można przenosić na potomstwo. Przez całe życie osobników ich genomy oddziałują z ich środowiskiem, powodując różnice w cechach. Osoby z pewnymi wariantami cechy mogą przetrwać i rozmnażać więcej niż osoby z innymi, mniej skutecznymi wariantami. Dlatego populacja rozwija się. Czynniki, które wpływają na powodzenie rozrodczości są również ważne, problem, który Charles Darwin rozwinął na przykład w swoich pomysłach dotyczących wyboru seksualnego.
Definicja słowa natural selection w słowniku
Definicja selekcji naturalnej w słowniku jest procesem prowadzącym do przeżycia tych osobników z populacji zwierząt lub roślin, które są najlepiej przystosowane do panujących warunków środowiskowych. Ocaleni mają tendencję do produkowania więcej potomstwa niż ci mniej dobrze przystosowani, tak, że charakterystyka populacji zmienia się w czasie, a więc proces ewolucji.
CYTATY ZE SŁOWEM «NATURAL SELECTION»
Słynne cytaty i zdania ze słowem
natural selection.
Natural selection is not an inflammatory phrase; evolution is.
It is a shock to us in the twentieth century to discover, from observations science has made, that the fundamental mechanisms of life cannot be ascribed to natural selection, and therefore were designed. But we must deal with our shock as best we can and go on.
It was a shock to people of the nineteenth century when they discovered, from observations science had made, that many features of the biological world could be ascribed to the elegant principle of natural selection.
Since natural selection requires a function to select, an irreducibly complex biological system, if there is such a thing, would have to arise as an integrated unit for natural selection to have anything to act on.
The difficulty of looking at a system like natural selection if you have any sort of moral sense yourself, is almost what makes it beautiful.
Natural selection shaped the human brain to be drawn toward aspects of nature that enhance our survival and reproduction, like verdant landscapes and docile creatures. There is no payoff to getting the warm fuzzies in the presence of rats, snakes, mosquitoes, cockroaches, herpes simplex and the rabies virus.
The real problem with natural selection is that it makes no intuitive sense. It is like quantum physics; we may intellectually grasp it, but it will never feel right to us.
It is hard to explain the huge variety of diatoms - a microorganism that has 100,000 species - in terms of natural selection.
There are good reasons why natural selection has become widely accepted as an explanation of evolutionary development. When applied to mammals and other large animals, it fits perfectly. But we cannot assume that all evolutionary steps arise from selection, particularly when looking at smaller animals.
The Galapagos Islands are probably the most famous wildlife-watching destination in the world. And no wonder - it's almost impossible to exaggerate the sheer spectacle of the place that provided inspiration for Charles Darwin's ground-breaking theory of natural selection.
