Planet Earth and Biological Anthropology

This Blog Discusses the Planet earth and how Evolution happened in different periods. This Blog Primarily focuses on the Proterozoic Era, but this series of Blogs will explain everything about the Other Eras.

The blog will help you to Understand,

What was the Condition of the Planet Earth in the Beginning?
How did it all Begin?
What is Proterozoic Era?

What are you, and what is the meaning of Your existence?

Please don’t consider me as your personal Philosopher. Anthropology denies the Philosophical statements by providing the Scientific fact. This Factualness makes Anthropology work as the Database for the History of Humankind. According to me, Anthropology is the Scientific explanation of History.

Battles and Political ideologies changed and shaped the History of Humankind but do they affect the World?
The answer is NO, they harmed the World, but they could never affect the World.

We all are just a mere part of this vast cosmos. This planet earth is just one habitable Planet out of some other billion planets. Still, we need to study the Life form of this Planet, and this is where biological anthropology helped us.

Charles Darwin explained How Evolution happened, but it is still one of the biggest questions: Why did this Evolution happen? This Question made the days of Charles Darwin restless.

For the Question, what are we? We are nothing but the animals like Sparrow and Lion, but we use our brains to think and imagine, which is why our species is dominant.

But what is the meaning of our existence? It is still an unanswerable question, at least from the Scientific perspective.

Philosophy explained the meaning of existence. It is morally correct, but biologically and scientifically, it is unanswerable.

Planet Earth – At a Glance

According to NASA, Earth is 4.5 billion years old (plus or minus 50 million years). Ancient Hindu cosmology mentioned that the Earth is 4,320,000,000 years old.

Over the 4.5 billion years, The Earth witnessed the Evolution and the Diversification of that Evolution.

Now you must be thinking about what is so special about Diversification?
Because of this Diversification, the African and Asian lion is different. Diversification also happened with humans, so we see the various races of human beings on the other continents.

This Diversification happens because of the habitable conditions of a Species. Some live in good conditions. In contrast, some live in the bad. Still, this diversification program mutates these living beings and makes them sustainable for this change.

In the city in which I live, its average temperature is 40 degrees Celsius. Still, yet my body is diversified to adapt to this change.

Diversification happens not only because of heritage or habitat but also of Sexual reproduction, genetic drift, and natural selection pressure. We will discuss this in our upcoming book.

Genesis of Livingness on Planet Earth

Fossils suggest that all life begins in the Sea, and the beginning of the living hood started just after creating the Oceans of the Planet Earth. It started in the form of Microbes. They were single-celled microscopic organisms, but I wonder how these Aquatic animals formed from one microbe and how the Amphibians like Turtle, frog and Tortoise started their lives. It is so fascinating to think further when we study the Reptiles like snakes and dinosaurs.

We all are a part of this Evolution, and we are Mammals. Ever wonder how cool it is to study other species when you also share the same core of Evolution and Diversification with them?

This is also one of the most influential questions in the World. How can only human beings have this kind of Strong bond between Imagination and thinking? Chimpanzees can think, but they cannot imagine being rich.

Proterozoic Era

It began when the Planet earth formed. This Era is as ancient as the age of the Planet. It ended 600 million years ago.

This Era came to an end when the first Diversification ended. Proterozoic Era contributes the majority of Earth’s History.

In this Era, the first living form came to life.

You must be familiar with the Fossils. Scientists conduct research on them to find out how old the stuff is, and when they did this on the fossils, it is found that this Era was filled with the Clusters and chains of Blue-green algae.

From about 3.5 billion to 1.5 billion years ago, we find these kinds of Fossils.

With the simple mathematics, 3.5 – 1.5, it can be said that the Prokaryotic lived for the first 2 billion years.

Prokaryotic means Single-celled organism.

But starting around 1.5 to 1.2 billion years ago, life becomes more diverse. At this stage, we began to find out the existence of eukaryotic cells.

Eukaryotic cells are cells with a nucleus. The Plant cells and Animal cells are examples of Eukaryotic cells

By 1 billion years ago, we find indirect evidence of Multicellular organisms.

Between 1 billion and 570 million years ago, we saw the Diversification of the types in fossil organisms.

In this Era, life was too small and confined to the limited habitat.
