AP PSYCHOLOGY

Detailed explanation-1: -Darwin now had the framework of his theory of natural selection “by which to work", as his “prime hobby". His research included extensive experimental selective breeding of plants and animals, finding evidence that species were not fixed and investigating many detailed ideas to refine and substantiate his theory.

Detailed explanation-2: -It turned out that Darwin was more interested in natural history than medicine-it was said that the sight of blood made him sick to his stomach. While he continued his studies in theology at Cambridge, it was his focus on natural history that became his passion.

Detailed explanation-3: -In 1828, Darwin went to Cambridge University to study for priesthood, earning a bachelor of arts degree at Cambridge University in 1831. Darwin continued to develop his interest in rocks, fossils, animals, and plants. He became friends with two Cambridge professors, geologist Adam Sedgwick and botanist John Henslow.

Detailed explanation-4: -Darwin’s theory consisted of two main points; 1) diverse groups of animals evolve from one or a few common ancestors; 2) the mechanism by which this evolution takes place is natural selection.

Detailed explanation-5: -Darwin’s goal was to study the natural history of the areas they were to explore. The observations he made during the five-year trip led him to wonder how new species developed. To explain this process Darwin formed his theory of natural selection.
