Nonsense you cannot prove that any of two those fossils are related let alone all of them.
FoeHammer.
you are absolutely right.
of course the evidence does not prove transitional forms. the evidence just sits there, it doesn't actually do anything.
people are persuaded that things are true, this is a function of the evidence presented.
however science doesn't do proof.
it does evidence.
and what it does with the evidence is persuade people who know the necessary underlying theory, that the evidence is beyond reasonable doubt demonstrating a principle. In these case, for anyone adequately trained in evolutionary theory, the evidence for transitional fossils is beyond reasonable doubt.
the evidence does not persuade people who:
1. believe that the evidence is false
2. believe that the system is false
3. who do not know enough of the system to understand the relationship of the evidence to the whole system.
so you are right.
the evidence does not persuade you that there are transitional fossils. but this is not the science's failure, it is yours. the evidence that it is yours is the large number of people who looking at the same evidence find it persuasive.
