Answer 1

Homology or diversity maybe , there the most likely I think , could be wrong though .

Answer 2

Answer 3

Glad to be of service it I think diversity is more likley , Homology is tricky and a famous evo bio guy ( I forget who ) said that " we can only infer homology with more of less certainty " and that holds true to this day .
