Tails We Lose

If you are not one of those people who believe that us human turned up on Earth fully formed after a bit of dirt scraping and nostril blowing then you are probably a follower of evolution, the idea that all species came from a common ancestor and change and gradually change over generations.
Our evolutionary journey means we are now generally shorter, lighter and smaller than our ancestors were 100,000 years ago and our brains have got smaller, have smaller jaws and therefore own less teeth as well as shedding most of our hair which all come with some benefits but a study published in Nature, losing our tails was an evolutionary boo-boo.
We lost our tails around the same time as we began standing upright and walking on two legs but we still have the coccyx as an evolutionary hangover from this tail-bearing ancestry as well as causing back pain which is the largest contributor to disability worldwide according to the Global Burden of Disease study.
Scientists explain that the amount of time it took for humans to move from quadrupedal to bipedalism did not allow our musculoskeletal system to properly adapt and all that extra pressure that is added to the lower back without the adaptation results in pain in the lower back, legs and feet.
It did give a great line to one scientist though who said that: 'If an engineer were given the task to design the human body, he or she would never have done it the way humans have evolved' which is sound advice but millions of years too late so thank heavens our brain developed enough to invent painkillers and ergonomic chairs.
