Where Did the First Humans Come From?

Posted on

This time I will discuss the origins of humans. Do you already know where the first humans came from? To answer this question, of course there is a long discussion related to taxonomy and human cousins. For that, see my discussion below.

Who is the Human?

Before answering the question who is human, we need to refer to taxonomy. Taxonomy shows that humans are an order of primates. Does that mean we are descendants of apes? This question cannot be swallowed raw. Even answered in black and white.

The human order is primate, but humans have a derived taxonomic classification. Humans are included in the Hominidae family with the genus Homo. The Hominidae family is known as the big hard. The Hominidae family is known for four generations that are still living and living on earth, namely chimpanzees, gorillas, bonobos, orangutans, and humans (Homo).

There is also a term hominin which is defined as humans and human relatives who are more than chimpanzees. Homo is the Latin name for humans. Homo is not the only human who is still alive today.

Homo sapiens (the wise man), related to Homo neanderthalensis cousin, Homo heidelbergensis. As for the other names, Homo rudolfensis, homo ergaster, homo floresiensis, and others are still being debated.

The earliest fossils of the genus Homo were found in East Africa. Humans first migrated from Africa to Asia between 2 million and 1.8 million years ago. Then entered Europe about 1.5 and 1 million years ago.

The fossil species of the early genus Homo have the same brain and body sizes as Australopithecus and lived 2.3 million years ago. The difference with Australopithecus is its diet. The fossil was named Homo habilis (life span 2.3 to 1.4 million years ago).

Human evolution

Human evolution is a long process of change. One of the characteristics is bipedal, which is the ability to walk on two legs. This capability developed over four million years ago. Homo habilis at that time could have walked on two legs. Another key point is the complex brain and the ability to create and use survival tools.

The process of evolution involves a series of natural changes that cause species or populations of organisms to emerge, adapt, and then go extinct. Species or organisms originate from a biological evolutionary process. As in animals that reproduce sexually. Even humans are included.

Evolution occurs when there is a change in genetic material, namely DNA that is passed down from ancestors or parents in a different proportion of genes. Genes represent segments of DNA that are the chemical code for making proteins. The information in DNA can mutate. Genes influence the behavior of a developing organism during its lifetime. Of course it will affect the survival of these organisms.

It is believed that evolution will not change a person. This changes population growth and development. Offspring inherit genetic characteristics that increase their chances of survival and childbirth. Genetic changes also change the way species live. Like what they eat or where they live.

There is a lot of debate among scientists about this evolution. The human lineage diverged from the apes at least seven million years ago. For example, Australopithecus is thought to be the closest to Homo. Her name is Lucy, an Australopithecus afarensis who was 3.2 million years ago.

Homo took advantage of fire around 1.8 million to eight hundred thousand years ago. In fact, all developments become clear, for example language, art, agriculture that have appeared in the last hundred thousand years. The evolutionary curtain is certainly difficult to trace because there are missing links or chains. Scientists say chimpanzees did not evolve into humans. The bloodlines of the two are different.

About the First Modern Human

Modern humans, namely Sapiens, are the last human species on earth. Humans share commonalities and generic affinities with other primates. Humans first evolved in Africa. In fact, early humans lived between six million and two million years ago when they came from Africa.

Homo sapiens first appeared in Africa more than three hundred years ago. However, there is a debate among scientists, were people from Three hundred years ago the same as today? That is, when they live their mental capacities are the same as modern humans today?

Even so, modern humans have recognized and left evidence such as the use of pigments that might be used to paint the body. There are also remains of pictures or lukisa on the rocks or caves, shell beads, arrows, and various other cultural relics.

Scientists studying Homo sapiens were able to migrate on a large scale around the world. Homo sapiens from Indonesia, for example, was able to navigate the oceans using boat technology to the continent of Australia. There is other evidence that the Pleistocene Ice Age formed a bridge connecting Asia with North America, allowing sapiens to migrate to America.

Scientists believe that Homo Sapiens was capable of immigration on a large scale due to the development of language about Fifty thousand years ago. Language is considered very effective for communicating, making plans, solving problems, and managing many things.

Conclusion

Where did the first humans come from, of course, through a series of evolutionary processes that are still a mystery to this day. This is because of the missing link. The earliest fossils of the genus Homo were found in East Africa. Humans first migrated from Africa to Asia between two million and 1.8 million years ago. His name is Homo habilis who lived 2.3 to 1.4 million years ago.
