I think that largely depends on how you look at it. As with any topic, Greek philosophers had widely different opinions across schools of thought and generations. Many highlighted rational thinking as the line between humans and animals, while still thinking animals intelligent and emotional. I do agree with your point on Darwin, but why that point works is exactly because his work contrasted with the rest of his peers. His work was also far from being widely accepted at first, and was met with heavy skepticism on many, if not most fronts. It was only later that this became a widely accepted part of science.

OK, I think I see what you meant: Not that the "misnomer" arose in the Victorian era, but that the Victorian era was the last era in which you would expect to encounter this "misnomer".

As a counterpoint, I recommend reading Everlasting Man, by G. K. Chesterton. If humans are just animals, they're the most bizarre animal we've ever seen.
