Kinda like how a car and a tricycle both have instructions for how to attach an axle?You got it- inadvertently. When the DNA looks similar as predicted by the morphology, then what do you say?

Because you have so little evidence currently? That's called "faith", and it should make you question your presuppositions.And, then when bones of a suspected common ancestor of dolphins and hippos is found, what a great party there will be.
They did find some teeth of a hippo ancestor Epirigenys lokonensis that are similar to dolphin teeth. Here, the gross morphology between the dolphin and hippopotamus is not readily apparent, but internal structures help us see a potential connection along side the obvious DNA connection.Because you have so little evidence currently?

If your currently available evidence were strong, then why do you predict such a party when more evidence is found. If you're searching for truth rather than for confirmation of a particular theory (with specific epistemological implications), you should rejoice over any progress--not just for those that you think confirm your viewpoint. I didn't see much rejoicing when dinosaur soft tissue was found, or when radiocarbon was found in diamonds and other objects too old to have it.They did find some teeth of a hippo ancestor Epirigenys lokonensis that are similar to dolphin teeth.

It is not faith, it is a hypothesis among many.
When two lines of research converge it is extra fun. This is a human thing.If your currently available evidence were strong, then why do you predict such a party when more evidence is found.

Question begging nonsense!But, it was exciting when we corroborated earlier theories about dolphins being more related to hippopotamus than sharks via DNA similarity.
When the base instructions are exactly the same for two structures, that is amazing. Not true for the bike and car. btw.Kinda like how a car and a tricycle both have instructions for how to attach an axle?
Well they're both mammals. Why wouldn't you think mammalian DNA would be more similar to another mammalian DNA than to a fish's DNA? Or did you 'flip-flop' what you were trying to say?But, it was exciting when we corroborated earlier theories about dolphins being more related to hippopotamus than sharks via DNA similarity.
My answer: You're speculating well beyond a reasonable point based on ASSUMPTIONS that you've already made about their past.Right Diviner,
Why do both whales and dolphins have hip bones/ rod shaped pelvic bones?
My answer: They are evolutionary remnants from when their ancestors walked on land more than 40 million years ago.
Sure they are: attach axle to vehicle, then attach wheels.When the base instructions are exactly the same for two structures, that is amazing. Not true for the bike and car. btw.
Not when they have the same Designer.When the base instructions are exactly the same for two structures, that is amazing.
This is not your answer. This is your reaction to my answer.My answer: You're speculating well beyond a reasonable point based on ASSUMPTIONS that you've already made about their past.
It's a valid answer. Everything in your "answer" were pure speculation based on your false paradigm.This is not your answer. This is your reaction to my answer.
Sorry, no. The question is why do whales and dolphins have pelvic bones similar to those that are condusive for walking?.It's a valid answer. Everything in your "answer" were pure speculation based on your false paradigm.
Up until the 17th century whales and dolphins were considered fish because they looked like fish. Internal structures and DNA shows us that despite their out look, the y have more in common with mammals. Before DNA was mapped we hypothesized that there was a land mammal ancester of both sea mammals and land animals. The structure and sequence of the DNA supports this.Well they're both mammals. Why wouldn't you think mammalian DNA would be more similar to another mammalian DNA than to a fish's DNA? Or did you 'flip-flop' what you were trying to say?
Again, you make wild assumptions.Sorry, no. The question is why do whales and dolphins have pelvic bones similar to those that are condusive for walking?.
Compare some skeletons and get back to us on what you think.Again, you make wild assumptions.
What makes you think that they are "pelvic bones" in the first place? (hint: evolution on the brain).

Hope this helps.
Yes, they were never "pelvic bones" in the first place.Compare some skeletons and get back to us on what you think.
Interestingly, whale pelvic bones are not simply vestigial as once thought; they appear to help with birthing process.
