A 38 mm badge with a teal background and "I Love Charles Darwin"
Charles Darwin originally attended medical school as he was to follow in his father's footsteps and become a doctor. However he disliked the subject and instead pursued an interest in natural history. He spent 5 years travelling around the world, which gave him experience in geology and zoology. Over the course of the rest of his life he developed the theory of natural selectivity. His most famous work is the book "On the Origin of Species".
