Detailed explanation-1: -The theory of evolution is a shortened form of the term “theory of evolution by natural selection, ” which was proposed by Charles Darwin and Alfred Russel Wallace in the nineteenth century.

Detailed explanation-2: -Charles Darwin was a British naturalist who proposed the theory of biological evolution by natural selection. Darwin defined evolution as “descent with modification, ” the idea that species change over time, give rise to new species, and share a common ancestor.

Detailed explanation-3: -University of Cambridge PhD student Laura van Holstein just proved Darwin’s theory–that a genus with more species also has more subspecies. When Charles Darwin published “On the Origin of Species” in 1859, his evolutionary theories permanently shook up science and the way researchers studied the natural world.

Detailed explanation-4: -Darwin formulated his bold theory in private in 1837–39, after returning from a voyage around the world aboard HMS Beagle, but it was not until two decades later that he finally gave it full public expression in On the Origin of Species (1859), a book that has deeply influenced modern Western society and thought.
