"My Dear Emma, I have just finished my sketch of my species theory. If, as I believe that my theory is true & if it be accepted even by competent judge, it will be a considerable step in science." Charles Darwin, Letter to wife Emma Darwin, 5 July 1844
Darwin's health was failing. He had a >200 page abstract of his theory of natural selection and he knew he was on to something.
I'm behind on my posts - I know. But reading Game of Thrones and completely absorbed. Finished the second book last night in the wee hours and taking a break until school starts. So I hope.
