Instead of letting the environment 'select' those that do the best, people in the environment do it instead. It is more or less a rapid form of selection. Corn that we eat on the cob began as a much smaller and tiny cob until now.
Charles Darwin used data on artificial selection the least to support his theory of natural selection. While artificial selection played a role in shaping his understanding of how traits can change over generations, he focused primarily on observations of variation in nature and the role of competition and adaptation in driving the process of natural selection.
The four pieces of evidence that scientists point to as proof of natural selection are the fossil record, biogeography, homologous structures, and observable natural selection in action. These pieces of evidence all support the idea that organisms have evolved over time through the process of natural selection.
Scientists did not prove things then anymore than they prove things now. Evidence, masses of converging evidence support the theory of evolution by natural selection. Darwin, in his day, had much evidence to support his theory. All the way from artificial selection to island biogeography. Since that time the theory has moved on to where it is no longer just Darwin's theory, but modified and supported with so much evidence that the theory became the bedrock of biology.

An example similar to the evidence Darwin used to support natural selection is the variation in the beak sizes of Galapagos finches. Darwin observed that the finches' beak sizes varied based on the types of food available on each island, showing how adaptations can lead to differential survival and reproduction, supporting his theory of natural selection.
By giving the theory a mechanism of inheritance. Particulate inheritance, where each parent contributes chromosomes ( Mendel dod not know what a chromosome was and called genes " factors " ) that contain separate alleles that contribute to the progeny's traits. Darwin's idea of " blending " inheritance was completely wrong.

When a patient needs a machine, or a ventilator to breath for them, then that patient is on artificial life support. When a patient does not have the ability to breath on their own, or eat on their own, they will need artificial life support, or they will die.
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.

A coronary stent is an artificial support device placed in the coronary artery to keep the vessel open after treatment for coronary artery disease.
There is no proven theory of evolution only the physical evidence of what Chuck Norris has allowed to live.
No, Darwin's theory of evolution by natural selection actually complements the principles of biogeography. Biogeography, the study of the distribution of species, provides evidence of how species have adapted to their environments over time through the process of evolution. Darwin himself used biogeographical evidence to support his theory of evolution.
Charles Darwin, the creator of the theory of natural selection, was born 1809.
please some one answer this question because i need t for freaking science class.. thank you.. i need it pronto.. :D

Yes. If one cannot survive without intubation and mechanical ventilation (a respirator), then that would be considered artificial life support.
