Yep, success is success, in any medium. convergent evolution can be found wherever we find life, from vents to the upper atmosphere. Terrestrial biology has had four and a half billion years to try everything, and try it in 50 different ages. Where characteristics impart a benefit to passing on genes, it’ll probably find success.

I wonder after all those billions of years if we’ve had all the options tried, or if we’re just getting going. Probably depends on having a viable ecosystem tho. :|
