All the time-all around us. Stronger species survive and the weak are preyed upon and die out.
Genetic change is necessary for natural selection to take place
simply put, only the strong will survive
This process is called natural selection. It is the mechanism by which traits that provide a survival or reproductive advantage to an organism become more common in a population over time.
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.
It hasn't. Natural selection is a key part of the ecosystem itself.
In Darwin's time, it would be classified as "natural" selection.

natural selection
Everywhere where there is life.

Because natural selection only preserves incremental beneficial traits to the organism and many different areas of the organism are undergoing mutation and natural selection at the same time against the backdrop of the immediate environment. If a population of organisms, subject to allele change due to natural selection, is not in a changing environment, or split in a allopatric event, then adaptive change will be very slow, or will not happen at all and selection will winnow those variants and stabilizing selection is taking place. Regression to the mean of phenotype.
The process is called natural selection, where organisms that are best adapted to their environment are more likely to survive and reproduce, passing on their advantageous traits to the next generation.
Natural selection and artificial selection both involve an organism's traits being determined by how much they're favored. Then, the organisms with favorable traits pass those traits on to future generations.However, natural selection is caused by survival; the organisms with traits that increase their chances for survival and reproduction pass on their traits. As for artificial selection, humans purposefully decide which traits (like the most colorful one) of an organism to pass on.The similarity of artificial selection and natural selection is that they both can cause changes in the frequency of population.
The book, On The Origin Of Species, " suggested " that organisms evolve through the process of natural selection. The nonrandom survival and reproductive success of randomly varying organisms
Adaptation does not allow for natural selection: natural selection causes adaptation.
This may not be the answer you're looking for exactly, but evolution doesn't exist. Maybe the organisms have changed slightly over time (natural selection) but they did not completely evolve. God created them as they are.
Natural selection requires variation in traits within a population, differential survival and reproduction based on those traits, and inheritance of those traits from one generation to the next. These factors allow for the gradual accumulation of advantageous traits over time.
