Correction: three possible explanations to the origin of species in accordance to the stratta/fossil and biological species.<quoted text>
Except there's zero evidence of design. You have no designer, no mechanisms, and no scientific predictions on why we don't see other examples of common designs that do not fit with nested hierarchies.
Centaurs? Common design.
Pegasus? Common design.
Pigs with compound eyes? Common design.
Why don't we see any of these? All are possible under common design.
What is the likelihood of finding a fossil with feathers and three middle-ear bones?
Your terms are irrelevant.
Of course you do. You have assumed design based on zero evidence.
2. biological species given rise to new species (evolution).
3. spontaneous generation to ALL known different biologica species found on earth today and in the strata/fossil record.
Only possible answers to the origin of species!
