    And you missed the part about conserving mass. A bird that can fly, with the mass of a human, would be much bigger than a human (cause birds have very thin, hollow bones).

      You seem to be describing density (d = m/v). Preserving mass doesn’t really mean anything in this context without a discussion of volume.

          why would you assume density would be conserved?

          I didn’t. I pointed out that the person I replied was not describing mass.
