Answer: Thomas Malthus, who studied population growth.
Thomas Malthus was an English scholar. He is particularly well-known because of his studies on population growth.

However, this change did not last long, as population growth restored the original per capita production level. Therefore, instead of using surplus for improving standards of living, humans tend to use it to increase population. These conclusions were carefully studied by Darwin, and they helped him develop his own theories on natural selection.
