Charles Darwin: A Revolutionary Idea. Written by Rebecca Stay, Presented by (Your name)
In 1809, on February 12, Charles Robert Darwin was born the 5th of 6 children of Robert and Susanna Darwin, in Shrewsbury, England. He never really cared about school, and just wanted to be around nature: exploring, hunting, or collecting specimen. After his mother died in 1817, Charles's dad took him out of school because he was getting bad grades and seemed to have no direction in life. Charles Darwin went to several colleges, and it was in the second one that he met his to-be mentor, but the real opportunity came when he was asked to fill the naturalist position on a research voyage aboard the H. M. S. Beagle. Eager to begin the job, he accepted. It was in the first leg of the trip that Darwin began to develop a theory on how life changes to fit the changing habitats. The tropics of South America were rich in creatures, but the Galapagos Islands not only had abundance but also variation in species. On one island the finches had tough beaks, on another, long and skinny. There were long and short necked tortoises, flamingos, seals, fish, lizards, birds beyond imagination, and creatures of every shape, size, color, and behavior. And all these things gave birth to an idea. Throughout the whole trip, Charles Darwin collected specimen from all over the world and wrote over 1,500 notes. After he got back home to Shrewsbury, he summed the notes into one book, The Voyage of the Beagle, which got decent reviews. Then he just sat there, thinking about what he had seen and what it could mean. Suddenly, there was only one possibility. Animals could change to fit their environment. He wrote more books,some of them being On the Origin of Species, and The Descent of Man, and this time, scientists argued on and on. Natural selection was completely against what the Church of England was saying. how could it be true? Meanwhile, Darwin was getting sick, worse and worse. And in 1882, he died quietly in his house. Even if arguing, scientists agreed. Charles Darwin was a great man. He was buried about twenty feet from Sir Isaac Newton in Westminster Abbey. But his legacy lives on still. Hundreds of organizations and schools were named after him, including one of the northern Galapagos Islands. No, the world still remembers Charles Robert Darwin. After all, who would dare forget where we come from?
