If you ain't fit then you're more likely to die.
To the detriment of you progeny (if any).
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.
There is no " theory of evolution " as evolution is a fact. The theory is; the theory of evolution by natural selection and explains much about the fact of evolution. Charles Robert Darwin and Alfred Russel Wallace come up with the theory of evolution by natural selection, though natural selection is a phrase coined by Darwin.
The term that is often incorrectly used to describe evolution by natural selection is "survival of the fittest."
Basically, random mutation and natural selection. With a little genetic drift and gene flow thrown into the mix. Evolution, the change in allele frequency over time in a population of organisms.
Charles Darwin is most known for his theory of evolution, outlined in his book "On the Origin of Species" published in 1859. His theory proposed that species evolve over time through a process of natural selection.
natural selection
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.
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
The process of natural selection and evolution can vary in terms of the time it takes, ranging from hundreds to millions of years depending on the species and environmental factors. Evolution is a gradual process that occurs over generations as populations adapt to their changing surroundings through natural selection.
Natural selection is only the result of changing environments, mutation and the variation resulting therein. Natural selection is the process of adaptive change and the main mechanism of evolution that leads to speciation. Natural selection is a process as mutation and variation are grist to the mill of natural selection.
Evolution is the process by which species change over time through natural selection. Theories of evolution, such as Darwin's theory of evolution by natural selection, are explanations for how evolution occurs and the mechanisms driving it. In essence, evolution is the phenomenon, while theories of evolution are the explanations for how it happens.

Natural selection is the process which determines the shark's evolution. It is humankind that is threatening the sharks' survival.
Darwin's process of evolution was called natural selection. This process involves the survival and reproduction of individuals with advantageous traits for their environment, leading to gradual changes in a population over time.
