Life On A Low Gravity Planet 26.03.2020

Science fiction loves to take us to desolate alien worlds with low-gravity, and envision creatures evolved to those or humans adapted to those conditions or zero-gravity in space, and many planets we might one day colonize like Mars do have low gravity... but our assumptions about life on such places correct or what if we're making incorrect assumptions?
