Who were the first humans on earth?

This first year of history has been talked about, primitive people.

What were the first human beings?

At present, the academic community generally believes that the time of the first human ancestor is 7 million years ago, and there is no specific time and argument, and it is based on the transformation and reasoning of apes.

More than 2 billion years ago, single-celled algae organisms.

The first humans on earth lived in what is now Africa.

There have long been different opinions in the academic community about the origin of human beings and modern humans.

In the 67th decade of the 20th century, the academic community finally reached a basic consensus: the earliest human beings originated in Africa 67 million years ago;

About 2 million years ago, some of them left Africa and migrated to Eurasia and other places, becoming the common ancestors of the ancient humans found outside of Africa today.

The history of human civilization began with the invention of writing, and the earliest time was only seven or eight thousand years.

The main manifestations of the emergence of early human civilization are: (1) the Nile River valley in Africa, which established the early slave state of Egypt; the two river basins of Western Asia, where the ancient kingdom of Babylon was established; The Yellow River and Yangtze River basins in East Asia established the first Song Yin Dynasty and the Indus Valley in South Asia, forming ancient India. (2) Ancient Egypt had the Jinyu Pagoda of world civilization, and Cuba Bizhen formulated the world's first relatively complete written code - the Code of Hammurabi; Buddhism was born in India, and the Great Wall of China and the Four Great Inventions are famous all over the world.

3) The great river basin gave birth to human civilization because of its superior natural conditions such as water source and soil, but the struggle of human beings to maintain survival and development has made history.

Dinosaurs appeared 245 million years ago!

Dinosaurs ruled three geological epochs for a total of 165 million years.

However, during the Triassic and early Jurassic periods, dinosaurs still did not become a very powerful species, almost completely dominating the entire evolutionary process of animals.

By the end of the Jurassic period, very large sauropods had become the largest creatures ever on Earth.

The end of the Jurassic period was the peak of their domination of the earth, and they far surpassed other creatures of the same period in terms of diversity, intelligence, and size.

The earliest life forms on Earth were probably 100 million years ago, that is, 16 million years earlier than the age now accepted by the scientific community. A professional survey was published in the latest issue of the journal Nature on Thursday. The report concluded that the first life on Earth appeared hundreds of millions of years ago.

Two U.S. scientists who published the report noted that after careful analysis of a coral, they found that it formed 100 million years ago. This suggests that simple life forms at the microbial level had emerged on Earth at that time.

Mike Theis and Donner Rove, professors at Stanford University in the United States, who worked on the study, said the latest findings could potentially end the current debate over when life was formed.

Experts from Nature magazine point out that the work of Mike Theis and Donner Rove is very probatory, and the analysis in their article strongly argues that what they found is indeed the remnants of biological activity, and not the result of hot spring activity.
