In our mythology, people are made out of mud by Nuwa, and the theory of evolution lets us know that humans evolved through an ape, but have you ever wondered where apes come from? There are so many species of apes in the world, why have we become people? Do current apes still have a chance to evolve into adults?
There are many theories about the origin of life on Earth, and the current scientific community is more recognized by the comet, in the past, the world was hot and harsh, unable to really give birth to life, and the earth was often attacked by comets, comets and the impact of the earth, accidentally produced the original nature will not synthesize the material amino acids, it is part of organic matter, is an important component of life, they flow into the original ocean, so that this ocean is warm and contains life, although the environment is cruel, But still for the birth of life to create opportunities, for this primitive ocean, people call it the soup of life, in this bowl of soup, a large number of small organic molecules continue to gather, gradually synthesize protein DNA, and finally synthesize cells to produce the world's first life, which makes the environment on the earth still extremely harsh, very threatening the birth of life.
Among them, the first algae plants appeared in the ocean, it is the ancestor of all algae in the world, they can carry out the world's first photosynthesis, constantly release oxygen on the earth, accumulate to form today's ozone layer, the ozone layer can isolate ultraviolet radiation, so that the sunlight on the earth becomes softer, oxygen under ozone more and more, so that the earth becomes the cradle of life in the true sense, tiny life is gradually evolving into more complex and diverse forms with continuous development, and began to leave the former ocean , arrived on land to survive.
And the period of real biological differentiation on this land is about 542 million years ago in the Cambrian, archaeologists investigated the geological layers of this period, obtained a large number of biological fossils, and it is in this period that the earth has a real sense of biodiversity, and then the earth's creatures rise and fall, there is a large number of biological extinctions and revivals, about 65 million years ago, dinosaurs because of a meteorite hit the earth, and related animals and plants left the historical stage, only to have the opportunity to appear the ancestor of mammals, the ancestor of the ancestor beast, at this time the ancestor beast just experienced the mass extinction of dinosaurs, because of their small size , and good at digging holes, somewhat similar to today's mice, so that they could avoid the great disaster, survived, and with the complex evolution in it, we fast-forward to the emergence of a common ancestor of apes.
Our ancestors would have continued to live in trees like today's apes, but drastic environmental changes once again put forward a test, when the world ushered in climate warming, in fact, the earth will produce a general trend of warming and cooling every certain time, this warming makes the trees less and less, and finally let part of the ancient apes be forced to leave the life on the trees, since then it is doomed that apes are divided into two types to live on the ground and live in the woods, which are the two ancestors of our current apes, It is also doomed that the current apes have no chance to evolve into humans.
Seeing this, you may think of some wonderful questions, since this ancient ape living on the ground is the ancestor of human beings, will there be some apes in this who have not become humans and live on the earth, in fact, life on the ground is far more difficult than life in trees, apes do not have fangs and claws, and even the stronger fruit on the ground can not bite, which also gives birth to their talent for using tools, with continuous evolution, they begin to get started and take on more tasks, Finally, it evolved to humans walking upright, which also shows that apes that have not evolved a division of labor and are still living on the ground have basically eliminated no chance of survival.
Because the earth is still gradually warming in the overall trend, our ancestors began to degenerate their body hair, and gradually evolved into what we can now call the existence of ancient humans, and now archaeologists have found the oldest known human skeleton in Ethiopia, naming it Lucy, her appearance also represents that there were already human tribes that originated on the African continent, and later ancient humans began his long journey for better living space, and eventually scattered around the world, This does not mean that the mountaintop cave people in our country are not ancient humans, and the human beings scattered around the world are looking for suitable places to live and live, resonate with the land, gradually adapt to local life, and eventually constitute human culture everywhere.
Overlooking the entire universe that human beings can currently observe, there are few worlds that can be suitable for life survival, and the planet full of life can only be done by the earth, it can be said that the emergence of life on the earth is a one-in-ten million probability event, and the emergence of human beings, it can also be said that after continuous challenges to surpass other animals, and human beings are constantly evolving, especially we can find that the 80s, 90s and even 00s are a little different, where do you think human beings have evolved?
