Undeserved Credit
nMany biology textbooks give Darwin undeserved credit for the use of the finches as an example of natural selection in the theory of evolution.  The facts are:
nThe finches are not discussed in Darwin’s diary, except for one passing reference
nThe finches are never mentioned in Darwin’s book “The Origin of Species”
nThe natural selection observed in the 1970’s reversed direction soon after, resulting in no net evolutionary change
nSeveral finch species appear to be merging through hybridization
