Where did we really come from?
Humangee – a product of nature
Whether we like it or not, agree or not, humangee is a product of nature and the natural process of evolution. Humans are an evolved species, which are an output of the natural systems that exist on earth, and thus subject to the same parameters that determine natural existence over millennia. We can obviously caveat that in that many humangee may think that we have moved beyond those humble origins.
What is the natural system?
The earth and nature are demonstrated clearly by or biosphere or ecosphere. These comprise the collective biological and physical components of the planet that aggregate to make all of our ecosystems. This includes everything from plants, animals, insects, microscopic life, land, sea, air, climate and weather systems, and natural resources. It is the zone of life on the planet, which operates essentially as a closed system, apart from solar and cosmic radiation and heat from the earth’s core.
Like its many inhabitants, it is largely self-regulating, and all the systems work autonomously. There is a symbiotic relationship between the various ecosystems that helps maintain balance. The land, supports plants, trees, vegetation, agriculture, which are in turn supported by insects, pollination and other processes and enable consumption and use by various animals including humangee. Everything operates in natural cycles, and nothing is wasted. Natural products have a lifecycle, after which they return essentially to where they came from. It is an efficient and complete system, that follows natural laws. Humangee are an integral part of those ecosystems.
Evolution and Humangee
At a very high level this brief evolution summarizes the starting observations and origins of life on earth and progresses onto plants, living creatures and ultimately to HomoSapiens and human beings or humangee.
Up until around 1.6 billion years ago, it is clear that earth was an inhospitable planet, just like many others in our solar system. It did not support life as we now know it. The specific change event is not conclusive, as with any distant history. But it has been concluded from numerous aspects that a change took place to enable the transition from a hostile-to-life globe, into the lush, naturally evolved planet that we have the privilege of inhabiting today.

A range of studies clarified the chain of events, resulting in the initiation of photosynthesis in plants and effectively allowing the harnessing of energy from the sun. In essence, it became the first basis for a plant, and the earth’s first solar power plant – pun intended. Subsequent research and work suggest that all plants are essentially hybrids evolved from this change. An observation here may be that the nature of the range of the species on the planet from single cell bacteria, to elephants, bats, trees and humans, continues to evolve, and will continue to do so long beyond the lives of our great, great grandchildren.
This development of plants along with photosynthesis others changes, facilitated the development of the Ozone layer, which exists in the earth's stratosphere approximately 15-35km above the surface. It is created by ultraviolet light striking ordinary oxygen molecules resulting in a continuing process called the ozone-oxygen cycle.
It was another fortuitous evolution process which effectively protects life on earth from many of the harmful effects of the sun’s rays. It made this planet habitable. Over time, these changes and others have enabled a supergroup of organisms - the plants - to develop.
Between roughly two and one billion years ago (BYA) is our current estimate for the beginning of life on earth when a common ancestor gave rise to two main groups of life: bacteria and archaea. There was the first fossil evidence of cyanobacteria, and photosynthesis: The ability to take in sunlight and carbon dioxide, and obtain energy, releasing oxygen as a by-product. Eukaryotic cells with a version of internal organs emerged.
By 500 million years ago (MYA) Plants began colonizing the land. Fish split into two major groups: the bony fish and cartilaginous fish. And by 64-50 MYA: The primates split into two groups, known as the haplorrhines and the strepsirrhines. The strepsirrhines became lemurs, while the haplorrhines developed into apes, monkeys and humans. And by 6 MYA: Humans separated from the chimpanzees and bonobos - their closest relations, and by 1 MYA hominins began walking on two legs. The next stage of history began.
Take some time to either reflect or further investigate the appreciation of what it is to be a Human Being (as opposed to a human becoming)
