Funny that you can't mention one "unsubstantiated claim" nor explain how they are not substantiated. And yes, you are using a strawman. Your side can't even come up with a working definition of "kind". You can take a shot. Tell me how would you tell if two different groups of animals were of the same "kind" or not? If you use nonsense undefined terms you concede defeat.
But let's work backwards. You share a common ancestor with other apes, they are still an ape you are still an ape, no "change in kind". If so where is it? Creationists can't find it. When given the fossils of our recent ancestors they do not tend to agree on where the line is between "ape and man". In fact some of them have argued both ways on one species as being "fully ape" and "fully man".
You share a common ancestor with other mammals. That common ancestor was a mammal, you are still a mammal. No change in kind, or are you going to try to deny that you are a mammal as well? Again, no change in kind.
You share a common ancestor with other tetrapods. That means that you have four limbs, that ancestor was a tetrapod. No change in kind.
You share a common ancestor with other vertebrates. That ancestor was a vertebrate. Or are you going to claim that you do not have a backbone? No change in kind.
You share a common ancestor with other chordates, that means they have a spinal chord. You have one too, no change in kind.
I could keep going.
You really need to learn what the words that you use mean. Macroevolutoin is evolution at the species level and above. Exactly what I showed you. That was the definition given to it by the person that invented the term.
"Macroevolution is
evolution on a scale at or above the level of
species, in contrast with
microevolution,
[1] which refers to smaller evolutionary changes of
allele frequencies within a species or population.
[2] Macroevolution and microevolution describe fundamentally identical processes on different time scales."
https://en.wikipedia.org/wiki/Macroevolution
In other words macro and micro are both evolution.
EDIT: And your inability to understand observation does not mean that it does not happen. We can observe long term evolution. But you need to understand the scientific method to understand how.
Once again, you should never use the word "speculation". That word puts the burden of proof upon you and you cannot support any of your claims. That makes your use of the term a de facto breaking of the Ninth Commandment (or perhaps Eighth depending upon how you count them).
