Nah - it’s just intrinsically unlikely that we are the only species to develop such a variant. It’s no more speculative than a missing fossil sequence!
No - disagree with that interpretation. The physical realm is the realm to be transformed by the resurrection: Jesus did not abandon the physical, but re-create it.
Accordingly the physical world is a good creation, reflecting the mind and deity of the Creator. That does not mean “perfect” in some theoretical way, but it does mean the it’s the work of a craftsman (a metaphor common in Scripture).
Hence in some way “evolutionary creation” needs to be understanding how evolution is doing the work of the Father God who works all things towards their good ends, and towards his good purposes.
