Evolution.
My thinking about evolution took a giant leap, when I realised that it is not just whales and dolphins that changed their environment from land living to returning to the sea. There are countless other creatures that spend most of their lives in water.
Evolution for me, highlights the mechanism of natural creation, which is continuous while the planet is able to support life. There have been so many different species that have become extinct and the length of time that has taken place is mind boggling. For over 3.7 billion years evolution has taken place, and hopefully will continue.
The history of life has taken so many twists and turns and between them huge amounts of time have passed. Such as in the accumulation of water and later the increase in oxygen followed by the rusting process, all of which can be confirmed by examples of deposits in certain rock formations. It is interesting that the increase in oxygen may account for a time when insects became gigantic.
Many of the important changes do not seem to have been caused by any specific intention but mutual benefit or chance. Take mitochondria that has its own nucleus with DNA and is part of a much larger organism. This suggests that mitochondria were at one time an independent organism.
There have been drastic changes in the atmosphere of Earth from 2.5 billion years ago to the start of life. Bacteria flourished without oxygen. Some of that bacteria inadvertently contributed to the production of oxygen.
There have been at least five major freezing periods on Earth. The weather, the same as many other phenomenons, follows cycles of variation. It is ironic that we are living in the tailend of one of the freezing periods, when temperatures seem set to steadily keep on rising.
The history of life involving evolution could be claimed is not a straight path with a specific goal. Interesting and inspiring, formations of survival and science meet results, combine to produce the most highly acclaimed display of life in action.
