Such simple instincts as bees making a beehive could be sufficient to overthrow my whole theory.

If numerous species, belonging to the same genera or families, have really started into life all at once, the fact would be fatal to the theory of descent with slow modification through natural selection.

Man in his arrogance thinks himself a great work.

Why is thought being a secretion of brain, more wonderful than gravity a property of matter? It is our arrogance, our admiration of ourselves.

Species of the same genus would occasionally exhibit reversions to lost ancestral characters.

On the ordinary view of each species having been independently created, we gain no scientific explanation.
