Hi, Dr A.
Dr Adequate writes:
The prediction of the theory of evolution is as follows
If an embryo develops, and then loses, some significant feature during its embryological development, then that feature must be ancestral (as confirmed by other considerations, such as the fossil record, morphology, molecular phylogeny, and so forth).
I don't think this statement is entirely accurate: it's possible for a new feature to evolve for a short-term benefit during some stage of embryological development (I can't think of any examples in which this is the case, but it is entirely possible).
I'm worried about the false dichotomy your statement seems to be setting up: if we ever do find an ephemeral embryological feature that isn't ancestral, ToE could still explain its evolution.
