Answer:
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...
Explanation:
Comparing the skeletons of animals species provides support for the theory of evolution with respect to homologous and analogous organs.
Homologous organs are organs on different organisms that are similar in structures but different in functions while analogous organs are organs on different organisms that are dissimilar in structure but similar in functions.
Comparing skeletons to determine if organs are homologous or analogous may provide an insight into the common origins of two different animals or the different origins of similar animals.
