What was new about Darwin's theory of Human Nature - Essay Example (Mayr) Darwins theory, although successful in profoundly shaking scientific opinion about the development of life, could not explain the source of variation in traits within a species, and Darwins proposal of a hereditary mechanism was not compelling to biologists. Although the occurrence of evolution of some sort became a widely-accepted view among scientists, Darwins specific ideas about evolution—that it occurred gradually by natural and sexual selection—were actively attacked and rejected. Darwins theory nearly shattered the traditional Christian notion that humanity, poised between beast and angel, was literally formed in Gods image. Darwin pointed out, long before we knew that we share 98.5 percent of our genetic material with chimpanzees, that what looks back at us in the mirror is not the face of God but is kin to the earthbound apes. As the Edinburgh Review warned at the time, "a revolution in thought is imminent, which will shake society to its very foundations by destroying the sanctity of the conscience and the religious sense." (Zimmer) Darwins theory created a revolution in thought. It took over 100 years for the shock of our humble origins to wear off and for scientists to begin to address the serious implications that Darwinian evolution has for understanding human nature. During that time, greatly due to Darwins contribution, Western cultures faith in science grew, as faith in a Supreme Being guiding our destiny diminished. Something fascinating seems to happen when human beings begin to ponder the process of evolution. Something that calls forth awe at diversity and recognizes unity in life. Even Darwin, in The Descent of Man, used his own godless logic to envision a greater human unity that borders on the spiritual: "As man advances in civilization and small tribes are united into larger communities, the simplest reason would tell each individual that he ought to extend his social instincts and sympathies to all the members
