Evolutionary Biologists Puzzled Over Pain

Evolutionary Biologists Puzzled Over Pain

April 20, 2017

Painful tissue damage and inflammation tell you that they are there and need care, but even Richard Dawkins can’t find the evolutionary advantage of agony over a more tolerable, subtle ache or other signal. Without pain, you wouldn’t know that fire is dangerous or that your aching back needs treatment. Soreness is one of the crowning achievements of natural selection, but the body takes it to unnecessary heights.

Maybe the brain needs to tell us which sensations to prioritise. If you’ve not taken in fluids for two days, for example, your thirst is more important than your slightly bruised foot. If you’ve put your hand in a fire, though, it’s best to rescue your limb before you go hunting for the nearest stream. Varying intensities tell you what requires urgent action.

Neurology’s Viewpoint

People with disorders that prevent pain “usually come to a bad end,” says Dawkins. These patients must learn how to identify signs of harmful burns and breakages, but they often fail to adjust. They tend to suffer serious disabilities as a result.

It’s doubtful you’d take a more tolerable signal seriously, which lends credibility to the Darwinian explanation, but that doesn’t tell us the point of migraines and other painful disorders. Neuroscientist Vincenzo Bonavita believes that these seemingly useless pain signals force you to disengage from active life and get the necessary rest. In other words, even when that backache or headache isn’t pointing to tissue damage, you should take it seriously.

Pain is an important part of your health. Your nerves’ signals are as precise as a Geiger Counter. If you’re hurting, your body is telling you to hunt for a cause and some relief, so you need a pain specialist who takes your symptoms seriously. Pain Stop Clinics will do precisely that.
