Are we natural problem solvers?

We have been optimized to create tools to solve problems that allow us humans to prosper. We lead the existence of competing needs. Sometimes the need for food outweighs the need for sleep. These are two of dozens of needs that jockey for our attention at every second of the day. Luckily we have hardware and software that allows us to quickly and effectively meet these needs so that we can continue with our lives and carry on the human race. It seems as though humans were designed to face challenges and to solve problems.
