Bray has a logical game he wishes to play with you wherein he "proves" those fossils are not really transitory.
Or, more likely, he'll simply say you can't prove they are, so they're not.
But the key point to grasp is that every individual, without exception and every fossil too, is "transitional" between its ancestors and descendants, if any.
All of us without exception have minor, mostly harmless, DNA mutations which our parents & ancestors did not have, but which our descendants will inherit, along with their own new mutations.
Multiplied times thousands of generations these accumulating mutations allow for adaptations to new physical conditions -- for examples, high altitudes or malaria or milk from livestock.
But bray will only bray at all that, making it nearly useless to attempt educating him (or her).
yes I know that!
