How does the skulls change in the process of evolution? This “grateful dead t-shirt” shows that the latest product of evolution has hair on the skull.

On the back of the t-shirt, you see evolution of skeletons. I wonder if there is “evolution of soul” t-shirt around. It is now on sale in Amazon, and the price ranges from $23.95 - $25.95 (original price: $27.59 - $29.99)
