A major issue is where do body plans come from and then last 500 million years. Is this evidence of guided evolution?:-http://www.nytimes.com/2007/06/26/science/26essay.html-"One advantage developmental biologists have over paleontologists is that they can experiment on the development of these animals. Most of the genes in this network can be removed, and the developing embryo finds a way to compensate. But these five core genes, which form what Davidson calls a kernel, cannot be modified: change any one of them and no embryo forms at all. There is no reason to think that there was anything unusual about how this kernel first evolved some 500 million years ago (before sea urchins and starfish split into different groups), but once the kernel formed it locked development onto a certain path. These events, small and large, limit the range of possibilities on which natural selection can act. These questions about mechanism were not even being asked under the modern synthesis.-The failure to consider how biodiversity grows reflects an even more troubling flaw in the modern synthesis: it lacks any real sense of history. This may sound odd, as evolution is about history. A geologist would describe evolutionary theory as uniformitarian: "The present is the key to the past." ( my bold)This is the principle we use that by understanding how processes operate today we can understand past events. Evolutionary theory assumes that the processes we can study among fruit flies disporting themselves in a laboratory capture the broad sweep of evolutionary change."
