Every living thing on Earth is really, really lazy – and you and I are no exception. There’s a good reason for it too, food and water can be hard to come by for species without supermarkets. Even we had to be concerned about finding enough food before about 10,000 years ago. Several billions of years of punishing any and all inefficiency shaped pretty much all life into remarkably efficient things and have hardcoded one basic tenet into all organisms – take the path of least resistance.
When you have limited amounts of energy to expend it just makes sense. If you burn up more energy to catch dinner than you take in by eating it, you’re just not going to last very long. Taking the path of least resistance meant using the least amount of energy necessary to achieve your goals. In the past, that meant effiency. Efficiency meant survival. Everything worked great.
