If you know the history of the earth, then you must know that about 13.5 billion years ago, big bang made matter, energy, time and space. Yes, we studied this in physics.
Let me take you the exciting journey of human’s history, where we learned that we could learn and evolve our brain into mind. The one power possessed by humans is our thinking capability. That’s why we reached the highest level of the food chain before we had discovered that we could also cook our food before consuming.
Before leading you into thinking brain. First, see how our we evolved.
Well, if snakes, dogs and tigers have siblings, then we also had. To recognise who we are and how we evolved
#Rise of Homo Sapiens
About 2.5 million years ago, humans first evolved in east Africa. Around 2 million years ago, some of the human species left their land to their journey of exploration in North Africa, Europe and Asia. At this point, our siblings had evolved due to which they required to adopt certain traits for their survival. Our siblings such as Homo rudolfensis , Homo erectus, Homo neanderthalensis, Homo soloensis, Homo floresiensis, Homo denisova, Homo rudolfensis and Homo ergaster defined our ancestral family.
And, in the end, homo sapiens evolved with their thinking capability. Now, the only species which exist is Homo Sapiens. Many theories justify how only this species of humans existed in the world.
#top of Food chain
A comparison that showed that humans have larger brains in their body than any other species. This larger brain had invented tools before they acquired the top position in the food chain. Use of tools, large brains, lear̥ning abilities wasn’t the only advantages human had.
But, we had the social skills that encouraged us to live in groups and proved that Union is strength. Because of those, today we have taken the crown of the king from Lion.
The story about an early human, who scratched two pieces of rock and invented fire. But, what were the changes Fire bestowed us?
About 800,000 years ago, some human species occasionally used fire. To scare the other animals, to sharpen the tools, and the best part to cook. By 300,000 years ago, Homo Sapiens used fire in their daily routine.
Humans could use the fire in many ways, but the best way was to cook food. The fire has not only changed our outside environment but our internal environment too. It reduced the size of the internal organs of the human body. Devoted less time to eat, smaller teeth and squeezed intestine, Fire changed us enormously.
#ability to transmit information
New ways of thinking and communication showed between 70,000 and 30,000 years ago.
Well, every species has their own language but As the cognitive revolution began, but what made us Sapiens to conquer the world through its communication?
The answer is that we can connect to numerous sounds, make infinite sentences, and each with a different meaning. There is another theory that states that our language has evolved, not talking about lions and plants but a way of gossiping. Even at that time too, it was also important to know, who hated whom in the band, of early humans, who was sleeping with who and who was more honest. It leads to homo sapiens to be a social animal and how they transmit information among them.
That’s why you and I able to communicate through this post.
Since our social structures had evolved, we not only talk, but we also chat through text messages by social media applications.
But, the question is, how were they evolved their social structure, how they formed groups to survive?
Likewise, in today’s scenario, the leader must be the most affluent and amiable person in the whole group. Similarly, in the stone age, they elected a leader who could form a good relationship with each one of them. They hunt together, celebrate together, eat together, and that became the remarkable trademark, the strength of Homo Sapiens.
#spiritual and mental life
Why do you think early humans survive, and why did they sustain social cooperation?
The answer is their non – existence belief. Early humans believed in religions, laws and myths, which couldn’t be seen, but everyone abides it.
Well, evolution of thinking brain led us to believe in our myths.
That’ why today we are united as humans but divided by communities which can easily recognise by distinct surnames.
I hope you enjoyed the historical evolution and how we evolved as here we are today.
