Overproduction
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.

Natural selectionsurvival of the fittest or natural selection.
No, a frog is not an example of natural selection itself. Natural selection is a mechanism for evolution that acts on populations of organisms over generations, influencing the traits that are passed on to the next generation. Individual organisms like a frog can be impacted by natural selection, depending on their traits and how those traits affect their survival and reproduction.
Variation and competition are the basis of natural selection.When a population of organisms has variety (big/small, fast/slower, etc), and there is competition, then some of those traits will assist in winning the competition, and some will not, which will tend to mean the difference between an organism surviving versus not surviving, which in a large population will mean passing the genes for those advantageous traits on, which then means that those traits have been 'selected' for by the natural act of competition, thus 'natural selection'.
Natural selection.
Natural selection ' selects ' from among variations. Some organisms are better suited to their immediate environment and survive and out reproduce other organisms. All these organisms are genetically variant. That is the simple connection between natural selection and genetic variation. ( that variation coming about by mutation and recombination )
Natural selection needs competition in order to occur
Natural Selection
The selection of the organism that survives best in a habitat with limited resources and that organisms superior reproductive success is called natural selection.
When competition occurs between species, the stronger species remain. This process is called: natural selection.
According to Natural Selection organisms compete to live. Now saying that, Natural Selection encompasses a whole range of competition, from competing for food to competing for mates. It is this competition as well as adapting to environments that hones in on variation and drives the change in species.

Overproduction
Natural selection.
Evolution is the change in allele frequency over time in a population of organisms. Change over time and a fact. Natural selection is the nonrandom survival and reproductive success of randomly varying organisms and explains much about the fact of evolution.
