This evolution took place in three stages, each one linked to a historical circumstance.
But equally important was the accompanying evolution of the brain, with its expansion of the visual cortex to process the sharper and more colorful images it was receiving.
We now know that far from being an ideal masterpiece of design, our eye bares traces of its step by step evolution.
And in the not so distant future, the machines built with the precision and flexibilty of the human eye may even enable it to surpass its own evolution.
All of this implies there's a reason that evolution has produced this small proportion of lefties, and maintained it over the course of millennia.
And while there have been several theories attempting to explain why handedness exists in the first place, or why most people are right-handed, a recent mathematical model suggests that the actual ratio reflects a balance between competitive and cooperative pressures on human evolution.
But according to the principles of evolution, groups that have a relative advantage tend to grow until that advantage disappears.
If people were only fighting and competing throughout human evolution, natural selection would lead to more lefties being the ones that made it until there were so many of them, that it was no longer a rare asset.
But human evolution has been shaped by cooperation, as well as competition.
From the skewed distribution of pawedness in cooperative animals, to the slightly larger percentage of lefties in competitive hunter-gatherer societies, we may even find that the answers to some puzzles of early human evolution are already in our hands.
We happen to know of at least one such process that has lead to original, valuable, and even beautiful outcomes: the process of evolution.
And evolutionary algorithms, or genetic algorithms that mimic biological evolution, are one promising approach to making machines generate original and valuable artistic outcomes.
So how can evolution make a machine musically creative?
And what's interesting is that the salamander has kept a very primitive circuit, which is very similar to the one we find in the lamprey, this primitive eel-like fish, and it looks like during evolution, new neural oscillators have been added to control the limbs, to do the leg locomotion.
First, there were the laws like Maxwell's equations and general relativity that determined the evolution of the universe, given its state over all of space at one time.
We have made good progress on the first part, and now have the knowledge of the laws of evolution in all but the most extreme conditions.
However, this division into laws of evolution and initial conditions depends on time and space being separate and distinct.
This removes the distinction between time and space, and means the laws of evolution can also determine the initial state.
But for the majority of the human race, millions of years of evolution have fine-tuned the immune system so that it works for, rather than against us.
In fact, this earthly evolution has given rise to over 1100 known species of tardigrades and there are probably many others yet to be discovered.
Superficially, it makes sense because evolution works via reproduction.
This way, the genes of the most musical penises spread, leading to rapid evolution of insects' phalluses.
This is the next step in the evolution.
Thousands of years of human evolution has not only given us humans like Tibetans, who can thrive in low-oxygen conditions, but also Argentinians, who can ingest and metabolize arsenic, the chemical element that can kill the average human being.
But, and this is a big but, such evolution requires two things that we may not always have, or be able to afford, and they are death and time.
In our species' struggle to find our place in the universe, we may not always have the time necessary for the natural evolution of extra functions for survival on non-Earth planets.
But with every passing day, we approach the age of volitional evolution, a time during which we as a species will have the capacity to decide for ourselves our own genetic destiny.
And it's just really important to have these two things running in parallel and not overwhelm evolution.
Connectography represents a quantum leap in the mobility of people, resources and ideas, but it is an evolution, an evolution of the world from political geography, which is how we legally divide the world, to functional geography, which is how we actually use the world, from nations and borders, to infrastructure and supply chains.
In biology right now, we are on the very verge of being able to control our own genetics, what the genes in our own bodies are doing, and certainly, eventually, our own evolution.
