ola,
if you know they are from the same genus, but have progressed independantly ("isolated"); and "express variablility of the same "common" ancestoral genetic"
THEN - how can this be "redundant / non-viable" ?
unless...; maybe you picked "the wrong organism for your thesis"; that has not yet been "coded" (- "no biologist; to this time, has yet "reconstructed phlogeny of said isolated development of common ancestoral genus"") ?.
meaning for; in plain english; your thesis as it stands - is for the future, because people do not have the "understanding of the history of the organism you are talking about" ?
(- i.e. you would need to have the biology degree already to say so - and herein lies the problem; maybe you either "need a different subject for your thesis" OR luck that people will take for granted the "non-viable" (BUT common sense, very high probability) information that can "NOT YET be proven" in order for everything to be "viable".
