Many famous and powerful families have been renowned for their pairing of close relatives, including the Hapsburgs and some ancient Egyptian pharaohs, and marrying relatives—both close and distant—was in general more common historically when groups were smaller and more isolated.
Darwin had been hoping the government could accumulate broad population-based data about the frequency of cousins marrying and the health of their offspring, and he requested questions to this effect be included in England's census.
Darwin's request was denied, but his concern lives on today. More than half of the states in the U. The views expressed are those of the author s and are not necessarily those of Scientific American. Already a subscriber? Sign in.

In he entered Christ's College, Cambridge, England, to become a minister. He soon gave up that idea also, but he continued to study.
He attended John Stevens Henslow's course in botany the study of plants , started a collection of beetles that became famous, and read widely.
He received his bachelor's degree in On Henslow's recommendation Darwin was offered the position of naturalist for the second voyage of H. Beagle to survey the coast of South America. The Beagle left in December and returned in October During the voyage Darwin studied many different plants and animals and collected many specimens, concentrating on location and habits.
Darwin was influenced in his Beagle studies by scientist Charles Lyell's Principles of Geology —33 , which stated that present conditions and processes were clues to the Earth's past history. Darwin noticed on the trip that certain types of organisms existed only in certain areas and that many organisms had gone through changes that made it easier for them to survive in certain environments.
For example, he studied a type of bird called a finch and realized that there were over a dozen different kinds. The size and shape of the beaks of these birds differed depending on what kind of food was available in the area each lived in. Darwin's Journal of Researches was published in With the help of a government grant to cover the cost of the illustrations, the Zoology of the Voyage of the Beagle was published in five volumes from to A number of scientists wrote articles on fossils the preserved remains of creatures from an earlier age , living mammals, birds, fish, and reptiles.
Darwin edited the work. He contributed information on the habits and ranges of the animals and made notes on the fossils.
He also published The Structure and Distribution of Coral Reefs , for he had studied the coral reefs in the Cocos Islands during the Beagle voyage. In and Darwin wrote short accounts of his views on evolution change and improvement over time.
However, the publication of other related works around the same time caused great controversy dispute and criticism of the authors, and Darwin decided the time was not yet right for him to enter the argument. He decided to wait and do more research. Darwin studied the practices of pigeon breeders, he conducted experiments on differences in plants and animals over time, and he worried about the problem of plant and animal transport across land and water barriers—for he believed in the importance of isolation for the creation of new species.
In May Lyell heard of Darwin's ideas and urged him to write an account with full references. She died on Thursday, July 15, Robert dedicated himself even more into his medical practice even more than he had before, leaving the household to be run mostly by his elder daughters Marianne and Caroline.
Robert had always been an enormous presence in the house when he returned from work at the end of the day, but it had been tolerable as long as his mood was good. Now, however, he was almost always irritable and depressed. The house remained comfortable and well kept, but gloomy.
In later descriptions of his childhood, Charles wrote that he remembered very little of his mother, particularly since his sisters forbade him to talk about her. Charles looked up to his sisters as teachers. School for Darwin was never a joyful thing.
He was first educated by Caroline, and then spent a year at a day school in Shrewsbury. From there he was sent to the Shrewsbury School, about a mile away from The Mount, at the age of 8.
The Shrewsbury School was a boarding school run by the elder Samuel Butler that focused almost exclusively on the classics, a subject which Darwin found nearly useless. His lack of interest in school led his parents to worry that he had not inherited his fair share of the Darwin energy and intelligence. Towards the end of his schooling he made up somewhat for his mediocre performance by conducting experiments with his older brother Erasmus in a shed in the back of The Mount.
