Humanoid: Difference between revisions

Some people find it unlikely to have a universe populated by unrelated creatures that all look human, while others (including some biologists) believe that a species would naturally drift towards bipedalism when achieving sapience as we know it. Occasionally, shows present a reason for this to be the case. For example, the episode "The Chase" of Star Trek: The Next Generation explained the humanoid denizens of the Star Trek universe by advancing the story of a primordial humanoid civilization, the Progenitors, that seeded the galaxy with genetically-engineered cells that guide evolution toward humanoid life . In most cases, however, the reason for the similarity is not explained, and it is regarded simply as a dramatic convention.
