The scientific theory of evolution is supported by different types of evidence. The diagrams below show the skeletons of two different animal species. How does comparing the skeletons of these animals provide support for the scientific theory of evolution?

the gradual changes can indicate a climatic or enviomental change, which would in turn effect the diet or migration movements. this can cause evolutional changes in the basic structure of their bodies, completely or partially altering the skeleton. There is eveidence for the theory in the fact that there are documeted changes in the enviorment and things don't just change on their own...
