QUE SIGNIFIE NATURAL SELECTION EN ANGLAIS
Sélection naturelle
La sélection naturelle est le processus progressif par lequel les traits biologiques deviennent plus ou moins fréquents dans une population en fonction de l'effet des traits héréditaires sur le succès reproducteur différentiel des organismes qui interagissent avec leur environnement. C'est un mécanisme clé de l'évolution. Le terme «sélection naturelle» a été popularisé par Charles Darwin qui avait l'intention de le comparer à la sélection artificielle, maintenant plus communément appelée élevage sélectif. Il existe une variation dans toutes les populations d'organismes. Cela se produit en partie parce que des mutations aléatoires se produisent dans le génome d'un organisme individuel, et ces mutations peuvent être transmises à la progéniture. Tout au long de la vie des individus, leurs génomes interagissent avec leurs environnements pour provoquer des variations dans les traits. Les individus avec certaines variantes du trait peuvent survivre et reproduire plus que les individus avec d'autres variantes, moins réussies. Par conséquent, la population évolue. Les facteurs qui influent sur la réussite en matière de reproduction sont également importants, un problème que Charles Darwin a développé dans ses idées sur la sélection sexuelle, par exemple.
définition de natural selection dans le dictionnaire anglais
La définition de la sélection naturelle dans le dictionnaire est un processus résultant de la survie de ces individus d'une population d'animaux ou de plantes qui sont les mieux adaptés aux conditions environnementales dominantes. Les survivants ont tendance à produire plus de descendants que ceux qui sont moins bien adaptés, de sorte que les caractéristiques de la population changent avec le temps, ce qui explique le processus d'évolution.

10 CITATIONS EN ANGLAIS AVEC «NATURAL SELECTION»
Citations et phrases célèbres avec le mot
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.
