You won't find any adaptations in slowly reproducing species as there
aren't enough generations. You wouldn't have found any at the time of
previous extinctions either. Most species disappeared leaving a wide
open ecosystem for the few survivors to exploit. The adaptations
happened to the survivors *after* the catastrophes. You won't won't see
the speciations until after the human catastrophe when the ecological
niches are empty (assuming we allow such niches to reappear).
However, you can see adaptations in quickly reproducing species.
Antibiotic resistance, pesticide resistance, etc.
And then there are those species that are just happen to be fairly close
to what we want or we are to what they need, such as dogs (wolves) and
rats respectively.
