It was accompanied by a corresponding hostility to traditional religion. Taken in the order of their dates, they consist of:— I. Francis Darwin, New York: D. His formal education, such as it was, ended in Februarywhen he took the degree of M. Each new variety or species, when formed, will generally take the place of, and thus exterminate its less well-fitted parent.

    By autumn he had essentially given up his medical practice to devote more time to botany. But by this time, permanent settlements and railroads resulted in so many specimens coming in that Gray alone could not keep up with them. Goodale had a medical degree from Harvard and a solid knowledge of botany. Many of his lectures during this time were given at the Yale Divinity School. But why is it not just as likely that there were as many small genera nearly at first as now, and as great a disproportion in the number of their species? Both checks probably concur.

    Especially the family farm had a benign influence as a natural cooperative unit where everybody had real duties and responsibilities. It was during the winter spent in Egypt that Gray first grew his white beard. From Dr. On his second trip through the American West, he and Hooker reportedly collected over 1, specimens. In March he went to the United States, and afterwards devoted his life to scientific pursuits. Equally general, however, is the belief in what are called "permanent or true varieties,"—races of animals which continually propagate their like, but which differ so slightly although constantly from some other race, that the one is considered to be a variety of the other.

Darwin would then go on to explain his theory in depth to Gray in a letter on September 5th,which would later become part of Darwin's part of the joint presentation, with Wallace, of the theory of Natural Selection to the Linnean Society on July 1, see the second volume of Janet Browne's biography of Darwin, The Power of Place,New York: Alfred A.

For Darwin, a doctrine of design that included evil and suffering was not worth embracing. The different editions can be found on the web here: first edition p. By the expedition was in utter turmoil. This was the beginning of an extensive lifelong correspondence.

Domestic varieties, when turned wild, must return to something near the type of the original wild stock, or become altogether extinct. In the struggle it would have a better chance of surviving; and those of its offspring which inherited the variation, be it ever so slight, would also have a better chance.

If he does, I have nothing more to say. They next rented a villa in Sandown and Darwin pressed on, with the facts he felt necessary to support his "abstract" expanding far beyond the thirty pages Hooker had originally suggested. God caused neither--they are simply a part of a fallen world--but he can use both.

Asa Gray Professor of botany at Harvard during most of the middle half of the nineteenth century, Gray was one of the few members of the scientific community to whom Darwin revealed his theory before the publication of On the Origin of Species, and, from what I can tell, the only American.

Nineteen years! Over his career, he identified many hundreds of new plant species, and numerous others have been named in his honour, including the genus Grayia of the amaranth family. The case at present must remain inexplicable; and may be truly urged as a valid argument against the views here entertained.

The method of "induction," championed by Francis Bacon, had been the "standard" for scientific reasoning up until that time, although perhaps paid lip service more than strictly followed.
