Analogy

Analogy

(Science: biology) two anatomical structures or behavioural traits within different and unrelated organisms which perform the same functions in each organism but which did not originate from an ancestral structure or trait that the organisms ancestors had in common.

Instead, the structures or traits arose separately and then later evolved to perform the same function (or similar functions).

See: convergent evolution.

Compare: homology.

... trying to understand, as you seem to be. The formation of any biological structure or physiological system is NOT a random process. Any attempted analogy with randomly joining letters to produce a sentence completely misses the mark. Evolution is "descent with modification", as Darwin ...
