It has been two hundred years since Charles R. Darwin entered the world (1809-1882). An interesting fact is that Darwin was born in the times of great evangelical revival. Ultimately, however, Darwin came to shun orthodox Christianity. In The Origin of Species Darwin said:
“If it could be demonstrated that any complex organ existed which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down.” – Darwin, Charles (1872) Origin of Species 6th ed (1988) New York University Press, New York, p. 154
There are now many examples of biological organs and functions that could not possibly have evolved over aeons of time. For instance, consider how the process of blood-clotting would fare in the scheme of evolution.
