By writing a book that proposed human suffering and death from starvation because the population of humans went up exponentially but the supply of food goes up arithmetically. Darwin took this idea as an insight. He figured that populations of organisms produced far more progeny then the environment could supply with resources. So a selective process would be put in place. The fitter organisms would survive and reproduce while this much less fit would lose the struggle for existence.

no the theory of evolution is a species becoming more advanced not over populated
Thomas Malthus' work originated around population statistics and how they are affected by different factors. His work was instrumental for Darwin and Wallace's proposal of natural selection. Just to add, no he did not propose a theory of evolution.
Charles Darwin studied birds, medicine, and theory of evolution.
He might not of if Malthus had not been around but he depended on the works of Lyell.
I'm not sure Thomas Malthus had any theory pertaining to "evolution," strictly. Malthus was rather the prophet of "overpopulation." He put forward the idea that, if human populations kept reproducing, eventually we would crowd the world and create an ecological disaster.
There is no proven theory of evolution only the physical evidence of what Chuck Norris has allowed to live.
Genetic variations are produced by mutations and sexual recombination
Malthus's theory primarily focuses on the idea that population growth will outstrip the means of subsistence, leading to competition for resources. In nature, factors acting on organisms include predation, disease, and environmental conditions in addition to competition for resources. These factors in nature are often more complex and interconnected than the simplified model presented in Malthus's theory.
If you're referring to the guy who formed the theory of evolution, no. He died in 1882, I believe.
Edwin Darwin did not propose a separate theory on evolution. The theory of evolution is commonly attributed to Charles Darwin, who put forth the concept of natural selection as the mechanism driving evolution. Edwin Darwin does not have a notable theory associated with evolution.
