Charles Darwin, James Xavier and others in “Descent”

And therefore, I am convinced that natural selection has been the main, but, not exclusive means of species modification. I open the floor for questions.

[Stands up] Mr. Darwin, while your theory may explain diversity in the lower animals, how can your natural selection account for the human soul? Were we not created in God's own image?

I have not, uh, as yet, applied my observations to mankind. Though I may do so at some future point.

But, Mr. Darwin, shouldn't natural selection operate within any naturally occuring population, be at animal, vegetable or man himself?

Yes, yes, quite right.

And, given that we have removed ourselves from the mechanisms of natural selection, isn't mankind overdue for the next evolutionary step?

No, no, not at all. Man is still in direct competition with his fellows, and thus subject to natural selection. Uh, yes, you had a question.
