It should take very little time for the world to be knee-deep in beetles or earthworms.

These favourable traits will tend to accumulate in the population. Undermining scripture was not a popular thing. In summary, we can say the following about Natural Selection; The goal of life is to survive and reproduce, thereby passing on genetic information to the next generation. And his ideas became a cornerstone of modern biology.

However, there was a general acceptance of Darwin's ideas amongst the younger generations of scientists. Why was his insight a revolutionary one? His theory is one of the greatest contributions of our understanding of Science and life itself and serves as a foundation of the biological understanding of the natural world. Some individuals will not survive. On February 12th 2009  the world marked the bicentennial birthday. To confront the united establishment of science, politics and the church would get him into serious trouble. However, until Darwin came along, it lacked any plausible mechanism to support.

And their food supply, like that of a nation, is not infinite. Explain in three lines the concept of natural selection. So in 1859 Darwin's book, Origin of Species by Means of Natural Selection, was published. They are vulnerable to droughts and cold winters and other environmental assaults. Why is he still remembered? Darwin wanted to solve this mystery. But he knew his theories on evolution and natural selection went against established social and political order. And many others, were aware that the fossil record revealed a history of change. His genius was to suggest a robust and plausible mechanisn by which such changes could come about. Subsequently, their traits become more common in their descendents and in the population as a whole. Indeed, natural selection was not accepted as a key evolutionary force until well into the 20th century.
