They thought the evolution of new species is linked to environmental changes
About 99.9% of all educated scientists. The field of biology could no longer progress without the understanding of evolution via natural selection.
While living organisms tend to overprodue, the population still remains stable over time and across generations. therefore, there is competition, and success in competition is due to variability. Competition and variability together function to select the most adaptive characteristic, giving us natural selection
In short: Evolution. It means that a common ancestor is shared, but through small modifications over long periods of time, there is a large diversity.
Prior to sailing on the Beagle, Darwin was yet to observe different species of animals and plants in different regions. The observations were valuable in conceptualizing evolution. Before the voyage, Darwin believed that species were confined to different geographical locations, but ideas of species adaptation and evolution were nonexistent.

can someone help me please
Charles Darwin studied birds, medicine, and theory of evolution.
no the theory of evolution is a species becoming more advanced not over populated
Did you mean Charles Darwin? (Darwinism, Theologists and Philosopher?)
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.
Genetic variations are produced by mutations and sexual recombination
