There are a slew of errors in your comment. Charles Darwin's grandfather Erasmus was a member of several science societies; The Lunar Society, the Lichfield Botanical Society, and Derby Philosophical Society. Benjamin Franklin was also a member of the Lunar Society recommended by his friend Darwin. Erasmus and Charles Darwin's other grandfather Josiah Wedgwood secretly raised money to support the American Revolution which they coordinated with B. Franklin. Several of Earasmus Darwin's ideas about biology, and evolution at least hinted at what his grandson would discover nearly 50 years later. There were several other influential men in the late 1700s considering how life had developed. The most significant influence on Charles Darwin's biological thinking was Jean-Baptiste Lamarck (1744–1829). As a theology student, C. Darwin was very impressed with the creationist thinking of William Paley. Darwin wrote in his authobiography that he had memorized long tracts of Paley's 1802 book "Natural Theology or Evidences of the Existence and Attributes of the Deity."
