sure a cat is a suborder (Feliformia). not all animals from that order are interbreedable. you cannot breed a domestic cat with a lion for instance.. it wont work. So the cat is just a cat argument doesnt really fly. cladistics, remember, is simply our best organization and groupings of organisms based on genetic or phenotypic (visual) features. So we have 2 genetically and phenotypically different species capable of interbreeding and producing offpsring. Keep in mind these animals both come from the same genus and are classified as such so must be fairly closely related, but for semantics sake we have them under different species (although the visual differences are quite striking). Believe it or not donkeys are more distantly related to the common horse though.. so its more of a true cross breed when you mix a donkey with a horse (you produce an mule Not an ass sorry). A male horse and a female donkey you produce a hinny. A mule has a higher probability for fertility but usually the males are infertile.
So again i appologize as instead of ass i meant mule

We'r related to roaches? That's crazy. No wonder the likes of Hitler could see others on the same level as rats. Evolution allows people the excuse to naturally select their fellow man.

not really there is no direct lineage between us and roaches as i mentioned before. We would be considered very distant cousins with our common great 1.25x10^7 generations ago uncle or aunt being that bilatera creature, chaetognatha (given that the average life expectancy was 40 years per generation, a generously short estimate considering most bilatera have a very short life span.)
Well unfortunatley we do not abide by natures law, and this is my own diversion now. Since we manipulate the environment as much as we can to suite us instead of letting the environment shape ourselves, natural selection doesnt really work for us in the same sense as it does for animals. We are not segregated based on our physicality, stature ability to see hear or camoflauge but instead we all have our own benefits and individuality that play a role in teh society we live in. Social welfare helps those with disabilities to assimilate into our social structure and those who lack in certain skills but make up with alternative skills to do so as well. This is an anthropological debate which im not well versed in so ill leave it at that.

Racoon looking things become whales? That's crazy. I guess polar bears should soon start looking like whales too.

polar bears are closely related to dogs and bears so i would assume that the evolutionary strategy would lead decendents of the bear, if they indeed regress to the water, towards more seal like structure with a retainment of their hind limbs as fins.

What specific evidence do you need? |
something conclusive maybe? peer reviewed research. The problem with intelligent design is that they are searching for any plausibility to introduce miracles and god as the proclamation for the origin of stagnant species. This leaves the idea unopen to interpretation as faith cannot be challenged as it is not empirical.
The worst part about this is that it leaves science itself at a standstill with regards to this subject. With the disappearance of evolution from science we cannot further pursue how genetics manipulates organs and cell structures (with inferences to other organisms), pursue the causes of cancer and other hereditary diseases. Why pursue more when we have an unchallengeable answer (the supernatural cannot be contested since it is not testable).
this is essential goal of intelligent design, to close the book on disecting organism progression on the micro and macro level (as they are both synonymous.)
