The genome is the ultimate decentralized system-rampant redundancy, massive parallelism, no one in charge, no one looking over the shoulder of every transaction. But where complexity is rich enough for intelligence, such as in human organisms and organizations, and their robotic offspring, Lamarckian evolution is possible and advantageous. Ackley and Littman showed that computers programmed by humans could run Lamarckian evolution. Because this mechanism is a hybrid of evolution and learning, it has great potential in artificial realms. Every animal's body has a built-in but limited power to adjust to different environments.
Humans can acclimatize to life at a significantly higher elevation.
Our heart rate, blood pressure, and lung capacity must and will compensate for the lower air pressure. The same changes reverse when we migrate to a lower elevation. But there is a limit to the degree to which we can acclimatize. For us, it's around 20,000 feet above sea level. Beyond this altitude, the human body cannot stretch itself for long-term habitation.
