You can't compare biological evolution to politics!
Look evolution has repeated itself constantly, I never said that all evolutionary paths would look the same.
When you truly boil things down:
Sedentary lifeforms work under the same basic principle bee that Tree, Mushroom, or Coral Reef, all three have an anchor system and both, with the exception of the mushroom, have "Branches".
All mobile lifeforms evolved "limbs" be that fin, flipper, or legs.
The wing has evolved multiple times in earth's history in different animal phylum, orders, and families.
Bipedalism evolved independently in vertebrates
The teeth of vertebrates also repeat the same patterns based on diet. Claws, digging nails, and hooves also evolved independently.
