Basically, the ones who have the worst adaptions to survive in the environment it lives in, will die, while the ones with the best adaptions will thrive and breed, gradually making the better adaption dominant in the surviving members of the species. This is how you can have different features (say thicker beaks, longer tails, smaller eyes) in different sub-species of the same species - they've evolved for a different environment, and therefore have different adaptions.
Evolution, of course. Evolution can happen without natural selection in some cases; drift, flow. Generally though, natural selection causes evolution and then, by definition, would come first.
Natural selection is the process by which certain traits that provide a reproductive advantage become more common in a population over time, leading to evolutionary change. Evolution is the overall change in a population's genetic makeup over successive generations, driven by mechanisms such as natural selection. In essence, natural selection is one of the primary mechanisms through which evolution occurs.
Natural selection
Natural selection is the changing of organisms gradually over time. Natural selection and evolution are parts of environmental science due to them being the studies of organisms.
The modern theory of evolution may be referred to as natural selection, Darwinism, the Modern Evolutionary Synthesis, or sometimes simply evolution.
Genetic variation is important for natural selection to drive evolution because it provides the raw material for natural selection to act upon. Without genetic variation, there would be no diversity in traits for natural selection to favor or eliminate, and evolution would not be possible.
Yes, natural selection requires genetic variation to drive the process of evolution. Genetic variation provides the raw material for natural selection to act upon, leading to changes in the traits of a population over time.
No, natural selection is believed to result in evolution.
Perhaps not, but evolution can exist without natural selection.
Evolution by natural selection.
Evolution by natural selection.
Natural selection directs evolution; it cannot stop or prevent it.
Natural selection is one of the mechanisms that shapes adaptation and enables evolution.
Natural selection explains the process of evolution: evolution by natural selection. It basically means that species with the highest fitness (survival rate) will live, and be selected by nature for the characteristics they possess that make them more apt to survive. Because of natural selection, evolution occurs.
In evolution, natural selection is often called survival of the fittest.
Sexual selection and natural selection are both mechanisms that drive evolution, but they differ in their focus. Natural selection acts on traits that increase an organism's chances of survival and reproduction in its environment, while sexual selection specifically targets traits that enhance an individual's ability to attract mates and reproduce. This can lead to the evolution of characteristics that may not necessarily improve survival, but increase reproductive success.
