From the very beginnings...

Hello, welcome back everyone, its been a long time as I was busy with exams. Anyway, in the previous blog, we started a long journey to the edge of the universe. The universe is a very vast place filled with billions of galaxies including our own Milky Way galaxy. It would take more than the entire history of humans to even go through the list of galaxies. So this blog is not enough to cover everything, but I'll try my best to acknowledge you about the wonderful universe we exist in.

The Milkey Way Galaxy

Before we start to understand what the universe is and how it began let's first look in the mirror and figure out who we really are? We are the advanced species of the Apes, called Homo sapiens. It’s the scientific name for humans, Homo is the name of genes we carry and sapiens is our species’ name. humans (modern) evolved some over 800,000 years ago. Back then we were hunters, over the years we used our mind to develop weapons to hunt animals, to survive on the planet. After some hundreds of years later, we started exploring the world, it is said that the humans originated from Africa and by exploring the world we spread out across it. The tiny rock covered with evolved species. This spreading created geographical groups, and over the hundreds of years, each group surviving in its own environment Thus came the diversities and differences we experience among us like shape, size, diet, preferences, etc.

Human Evolution

The reason why humans flourished over the years is the brain. We are very good to analyze and compute our surrounding, we can also find patterns and predict some events in the future like when is next rain coming, How long winter will last(by the way winter is gone).In short, we predicted all the seasons. But we often forget that we are still living under the mercy of nature. Due to the natural balance in the plant kingdom, animal kingdom and nature, the seasons are predictable. If the balance in these kingdoms is not maintained (which is not due to Global warming and excessive animal slaughtering) then nature can be unpredictable and destructing, Earthquakes, Tsunamis, floods, famines begin to occur at an alarming rate. The biodiversities that developed for thousands of years can be destroyed within months.

Early Earth

If you feel that’s terrible our earth has suffered five such mass extinction, which almost destroyed every life on earth. Earth has formed 4.543 billions of years ago. It was too hot to support any life, the first life which is single cell microbes came around 3.5 billion years ago. The life flourished evolved in the newly formed watery planet until this natural extinction nearly destroyed it. We will cover those in the next blog.

Comment down your thoughts about the blog. Suggestions are heartily welcome. To conclude I would say, to be grateful for the precious life, given by nature. For what has given can be taken away. Nature does not owe us anything, we should stop polluting it. We need to change our ways to ensure people and nature thrive.

Charles Darwin said,

“It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change.”
