Nature's competition to see which of its creations can adapt the fastest, survive in its climate best, go on to gain awarness and build its own niche.
It's been exciting.
Ever since the first multi-celled organisms evolved out of our planet's primordial soups it's been a eco-survival race for supremecy.
A few billion years pass and you have us sitting comfortably in front of our computers. We're proverbial lottery winners in an ancient game of luck and adaptive skill. We've grown a lot past our primitive ancestors, higher and higher our brain capacities would increase throughout time, allowing us to invent. Fixing instead of throwing away, improving instead of moving on. We'd learn to stand tall an erect as we became better hunter/gatherers and we learned to communicate with eachother to form stable social systems.
Our evolutionary changes are heritable, continual, and become exponentially better... It's a very good system. We pass that which functions beneficially unto our children over millions of years and they adapt with their new abilities and features. As these new forms exist, the same deciding force which gave them their way of life will re-evaluate and adjust it as needed.
This subject is pretty touchy to discuss so confidently, but realize the word "evolution" has both a meaning in theory and fact. For this article sake, let's assume Darwin was right.
What will we as humans become next? It's been around 2 million years since our modern Homo genus first appeared in Southeastern Africa. Evolved from early primates, we finally reached our proverbial evolutionary mountain top once our ancestors came to our significant genus. After that it was all downhill.
Fast forward a couple million years - past our species' ever expanding brain and improving observational skills - and we reach our current form. Glorious us, eight fingers (+ two thumbs), long fertility, logical, extremely adaptable, innovative, curious, we rule.
Futurists, biologists, scientists and intellectuals from every field have all pondered at the question. How will we adapt to this new world? This world filled with extravagant technology and domesticated labor? It certainly is an interesting thought.
Some say we'll become big glops of goo, a result of our exponential lazyness due to rapidly progressing 'ergo-tech'. Some say we'll eventually educe a radical change ourselves. Two of evolution's major determining factors are interesting: it's either something that will substantially increase our reproduction rate to survive as a species, or something necessary added to our bodies in order to survive in the particular group's climate. Others speculate that we'll make good for a macromutation, a huge leap in a species' evolution to a highly advanced level in a relatively short time span.
Our technology might not want to wait around long enough for evolution to take us into the next, most efficient form. In-fact, the most probable scenario is one where we let technology speed up the process.
