Evolutionary biologists have made landmark discoveries recently all of which demonstrate the gradual development of life on earth. A fossil of a turtle with only a partially formed carapace gave support to the idea of a slow development from the simple to the complex even in the terrapin species. This ancestor of today's turtles, Maryland terrapins and tortoises exhibited a stepping stone in the growth of the shelled creatures.
Eight years ago the theory that certain Texans were living throughbacks to the 25 per centers, a branch in semi-human evolution that managed to make it into the modern era was recently confirmed by the discovery of an Alaskan specimen with the identical quarter of a brain. Both creatures have been labeled republicanus anus and offer hope that even these limited mutants may be able some day to develop a cranium that could accomodate a full size skull like today's Obamus Sapiens.
