Gamanit,
You asked “Lakewood Fellow- I’d like to hear an explanation from you about convergent evolution. Why are there both donkey zebras and horse zebras? According to standard evolution lines that should be impossible.”
Why would it be impossible? It would be quite likely if two animals are exposed to similar variables in their respective environments that they should evolve similar mechanisms for dealing with those variables.
As an aside it makes sense to cancel the Biology regent if you have a problem teaching students that the world is older then 6000 years old and if you have a problem with common descent…
