What are your referring to, specifically?
I will leave it as an exercise for you to ponder why the total lack of modern forms in the fossil record (below the very uppermost strata) is a problem for flood geology and a vindication for the ToE. Not that flood geology needs any more problems as it predicts nothing, is inconsistent with observed reality in too many ways to enumerate quickly, and would require numerous miracles to even come close to working.
First of all, Genesis is older than ToE. The burden of proof rests with ToE. Secondly, what does ToE predict? All ToE does is try to cram observations into a coherent body. Coherency is not proof.
