Hang on a minute!...
Let's not forget that any similarity is used by evolutionists to ascribe some sort of ancestry and familial connection between various kinds except when it doesn't. This of course renders the entire evolutionary assumption of similarity, be it morphological, genomic or behavioural, as bogus and unfalsifiable.
If evolutionists are simply able to invent terms such as homoplasy, convergent evolution, huge chunks of genomic information deleted, accelerated evolution of some genomic regions for some unknown reason not observed, new genes, duplications etc etc then you do not have a science. You do have hopefull scenarios and wishlists. All these terms are based on an evolutionary assumption. Really what you evolutionists are saying is all disimilarity will be hand waved away by some scenario or invented terminology of chance, while any similarity will be held to demonstrate an evolutionary connection.
The chaos theory of evolution - life - 18 October 2010 - New Scientist
As the above link speaks to, it is sad for evolutionists that they have found evolution to be chaotic and unpredictable. It is sad for evolutionists that in their fossil evidence traits come and go and no clear line is ever demonstrated. However that is the fact of your theory. Indeed the theory of evolution was more convincing before evolutionists found chaos and more research that poses more questions than it answers. Now all the attempts to reconcile DNA with morphology and all the invented terms required to handwave away anomolies has taken evolutionary theory into the land of non credibility.
