I am hoping to find a book that my father read to me when I was about 5 years old. After that, I remember reading it myself for years. This was a very long time ago…probably 1948 or so. No, I don’t remember the name of the book or the author but I can still visualize the black and white line drawings. The book told the story of how human beings “diversified” and the different races and ethnic groups evolved as they traveled across the Earth over centuries. The groups of people were called by various nonsense names….as I recall, there were names like Goopledops but that’s about as close as I can get. I know it was a hardcover book. I wonder if anyone remembers it. Thank you.
