Did Humans Evolve From Chimpanzees – The road to humanity is long and we are still exploring its ways. It began in Africa about 7 million years ago when our lineage split from our closest relatives, the chimpanzees. Our ancestors still looked like monkeys almost 4 million years later. This includes Lucy, a 3.2-million-year-old human ancestor found in Ethiopia, from a group called Australopithecines. In some ways, Lucy looks a lot like a monkey: she has a brain the size of a chimpanzee and long arms that suggest she spends her time in trees. But it also walked on two legs, like modern humans.

Hominids living today probably made simple stone tools, but our ancestors didn’t start looking and behaving like us until about 1.9 million years ago with the emergence of the genus.

. Fossils of Homo erectus have been found in Europe and Asia, marking it as the first hominid from Africa. He produced much more sophisticated tools than his predecessors, and was probably the first hominid to control fire. Some researchers believe it invented the stove, providing them with more energy to allow large brains to develop.

Living in Eurasia is believed to have given rise to the Neanderthals in the west and to an enigmatic group called the Denisovans in the east. And it is also considered our direct ancestor. However, new evidence completely rewrites this part of human history.

Evolved in East Africa about 150,000 years ago, became capable of modern behavior about 60,000 years ago, then migrated

To explore the whole world. But new analyzes of fossils, tools and DNA tell a different story. It seems that our species is much older – at least 300,000 years old – and has had sophisticated behavior from the beginning. We developed in Africa but, instead of originating in one region, we emerged from populations across the continent in a process called “African multiregionalism.” Everything from the identity of our last ancestors, when our species left Africa and what happened next, is up for review. It’s an exciting time to explore human stories; no doubt there will be more plot twists to come.

Darwin was wise. The idea of ​​evolution in any form was quite controversial in the mid-nineteenth century. Claiming that humans were shaped by evolution was explosive, as Darwin discovered when he published his entire book on the subject in 1871.

There are also scientific hurdles. Darwin had access to almost no fossil evidence that could show how, when, or even where humans evolved.

Did Humans Evolve From Chimpanzees

In the intervening years of man – or hominids, to use the appropriate term – the fossil record developed enormously. Much remains to be discovered, but the picture of our evolution is generally there. We know that our evolutionary tree first sprouted in Africa. We believe that our closest living relatives are chimpanzees, and that our lineage split from them about 7 million years ago.

No Giant Leap For Mankind: Why We’ve Been Looking At Human Evolution In The Wrong Way

However, the road to humanity is long. Almost 4 million years later, our ancestors still look like monkeys. Lucy, the famous 3.2-million-year-old human ancestor found in Ethiopia, has a small, chimpanzee-sized brain and long arms that indicate the species still spends a lot of time high in trees, perhaps retreating to the branches at night as chimpanzee . he still does But it has one defining human characteristic: it walks on two legs.

Lucy belongs to a group called australopiths. In the 40 years since its partial skeleton was found, fragmentary remains of even older fossils have been found, some dating back 7 million years. These follow the same pattern: they have chimpanzee characteristics and a small brain but appear to walk on two legs.

We also know that the Australopithecines probably made simple stone tools. Other than these advances, australopiths are no different from other apes.

– Why the first hominids looked and behaved a little like us. Some people now doubt that our genus evolved from australopithecine species, although exactly that is a matter of debate. This is probably Lucy’s species

, also a candidate. It doesn’t help that this transition probably happened between 2 and 3 million years ago, a time span with a very poor hominid fossil record.

Which is known from only a few bone fragments, which makes its study difficult. Some doubt that they belong to our genus, preferring to label them as

, and the first one we would recognize as looking like us, appeared about 1.9 million years ago. His name is Homo erectus.

It is different from earlier hominids. It’s completely down the tree and shares our passion too: all early hominins are only known from Africa, but fossils of Homo erectus have also been found in Europe and Asia.

Humans Are Primates

He is also an innovator. He produced more sophisticated devices than his predecessors, and was probably the first to control fire. Some researchers think it invented the kitchen, improving the quality of the diet and causing a surplus of energy that allowed the development of large brains. It is certainly true that the size of the brain

Growing dramatically during the 1.5 million years of our species’ existence. Some of the earliest individuals have a brain volume of less than 600 cubic centimeters, not much larger than the Australopithecus, but some later individuals have brains with a volume of 900 cubic centimeters.

Despite the success of Homo erectus, it still lacks some key human characteristics: for example, its anatomy shows that it may not be able to speak.

Population in Africa about 600,000 years ago. This species’ hyoid—a small bone that plays an important role in our vocal apparatus—is almost indistinguishable from us, and the anatomy of its ear indicates that it will be sensitive to speech.

Human Evolution (chapter 10)

Life in Eurasia also evolved, so Neanderthals in the west and the still enigmatic group called Denisovans in the east.

In the last 100,000 years, the last chapter of our history has opened. Modern humans spread around the world and Neanderthals and Denisovans disappeared. The exact reason why they became extinct is another mystery, but it seems that our species played a role. However, the interaction was not entirely hostile: DNA evidence shows that modern humans sometimes interbred with Neanderthals and Denisovans.

There’s still a lot we don’t know, and the new fossil has the potential to change history. Three new extinct hominids have been discovered in the last decade or so, incl

. Anatomically similar and related to the great apes (orangutans, chimpanzees, bonobos and gorillas) but distinguished by a more advanced brain that allows the ability to articulate speech and abstract reasoning. Humans show a marked straightness in body carriage that frees the hands for use as a manipulative limb.

If Humans Evolved From Apes, Why Do Apes Still Exist?

The answer to this question is challenging, since paleontologists have only partial information about what happened when. So far, scientists have not been able to detect a sudden “moment” of evolution in any species, but they can infer evolutionary signs that help frame our understanding of the emergence of humans. The evidence is strong in support
