Our Charles Darwin Little Thinker Doll is as adorable as Darwin was brilliant. He stands about 12 inches tall, looking every bit the scholar in his gray suit. He also has a full beard, bushy eyebrows, and a bald head as befits a genius of his stature. He's cute, cuddly, and even a bit inspiring. So get yourself a Charles Darwin Little Thinker Doll -- It would be a natural selection!
