You're behind the times Michael:

| Quote | Back pain vs evolution
Richard pointed out that evolutionary theory can be unproductive for research:
‘For example, the curve of the lumbar spine towards the front—the lordosis—was thought by evolutionists to be a problem, the result of man having recently adopted an upright position. So, some researchers blamed back pain on this, saying the spine had not yet evolved satisfactorily. If therapists have the wrong starting assumption, then it’s not surprising that treatments for lordosis are unhelpful. If a spine fracture causes a lumbar kyphosis (curvature in the opposite direction), that spine is significantly weakened.’1
He added that the creationist perspective has always been foundational to his research:
‘I start from quite a different position. From my understanding of human anatomy and physiology and my understanding of God, I say that the form of God’s creation always matches its function. So you can be sure that the form of the spine is perfectly designed for its function. God has made a wonderful spine. If you start with that premise, it gives you a head start when trying to understand the mechanism of the spine.
‘When you start to examine the biomechanics of the curved spine, asking why it’s that shape, and what’s good about it, you find that the arch of the spine has a beautiful purpose. Like the arch of a bridge, it adds strength. Because of that arch in the lumbar spine, a person with a lumbar lordosis can lift proportionally more weight than a gorilla with its kyphotic (opposite curvature) spine! So it’s not surprising that treating back pain with postures and exercises that restore the lordosis works exceedingly well.’2
The splendid spine
Injury Statistics
Our human spine is among the most ingeniously designed structures to be found anywhere. In this fallen world, it is estimated that 70–90% of all people in the US will suffer at least one back injury in their lives. Up to 25% become chronic. Much of this is exacerbated by failure to keep the surrounding muscles strong.
Since the spine is his specialist field, he could tell us about more of its amazing features:
‘My inaugural lecture in Aberdeen was “Upright Man”? and I tried to explain how the wonderful human spine is a perfect match between form and function. Things go wrong with the spine when we abuse it (if we fail to keep ourselves fit, or overload it, or have an accident). We are learning to use “foam filling”? in building (a sandwich of honeycomb material between two plates) to make something that is both light and strong, but the bones of the spine have been “foam filled”? with cancellous bone (with an open, latticed, or porous structure), surrounded by harder cortical bone, since the Creation.
‘The vertebral bodies increase in cross-sectional area as you go further down the spine, because in the upright position, the lower ones take more load. The bones are not denser, just bigger. By contrast, animals that walk on all fours have a roughly horizontal spine that is equally loaded all the way. So all their vertebrae are of similar cross-sectional area. Form matches function. If evolutionists were right in saying we had recently attained upright posture, our vertebral bodies should be like those of quadrupeds, but they are not.
‘We designed radial-ply tyres for motor cars, but God constructed the rim of the intervertebral disc with radial-ply fibres from the beginning. That construction makes a healthy disc stronger than the bones. When one examines the way the human body is formed and how it works, one is constantly amazed. It’s like looking at a piece of beautiful bone china and seeing the maker’s mark beneath.’ |
Apparently evolution has held up the treatment of back injuries for years, or so i've been told.
