Okay there has been one question that has really been getting to me lately. Are psuedo wyverns devolving or still evolving their wings. Tigrex's inability to sustain true flight and Akantor's vestigel wings would suggest they these traits devolved over time in favor of better land travel, but according to their descriptions they refer to their designs as primitive or ancient, suggesting these are old body types and traits.

Did these wyverns devolve their wings in favor of better land travel, or have they never fully evolved the wings of a true flying wyvern to begin with?
