Somehow in our evolution from whatever we were as quadrapedal sapiens to bipeds we were left with one 'weak spot' and that's the lower back. It's not really an engineering or evolutionary imperfection but rather it's our misunderstanding of the basic bipedal predilection to injure these muscles by using improper lifting techniques ,and, by not exercising, essentially, the abdomenal muscles which are actually the muscles which are used to lift (in conjunction with the legs shoulders and arms). Individuals who injure their backs in most cases simply don't know how to lift properly and actual subluxations of the spine are rare. Due modified sit-ups and approach every 'lift' as a world-class weight lifter and you won't injure your back. It's all about body mechanics and exercise.
