A TADPOLE does that... so what? That's supposed to prove that the evolution is reasonable?
A baby amphibian looks like a grown-up fish.
Did you know that a baby horseshoe crab looks like a grown-up (but quite extinct) trilobite? Did you know that a baby lamprey (primitive jawless fish) looks like a grown up primitive chordate? I suppose you knew that hatchling insects typically look like segmented worms.
In each case (supported by independent lines of evidence) it appears that the resemblance is based upon descent. That is, amphibians indeed spring from fish, insects from segmented worms, etc.
Yes, if added to all the other evidence collected over the decades.
I've yet to see any evidence collected by creationists/IDers. All I've ever seen them do is trash the one theory which HAS evidence to support it. Their arguments are entirely negative; no positive evidence is ever offered, save Scriptural quotes which are unverifiable.
