Where do we come from?
Religion and science give completely different answers to this question.
The Bible says that 6000 years ago, God created man in his own image.
Science believes that human beings evolved from apes.
Scientific knowledge is only 150 years.
Thank you for a Darwin in the world.
When Darwin set sail around the world on the Beagle,
He is also a devout Christian.
However, after five years of investigation,
He completely changed his view of the world.
The origin of species was first published in June1859165438+1October.
Proclamation: "What the Bible says" is complete deception.
All living things have the same ancestor.
Today's appearance is only the result of billions of years of evolution.
Reproduction leads to heredity,
Variation comes from accident.
Once the mutation matches the environment,
It will maintain and proliferate.
It's natural selection,
This is survival of the fittest.
So there is species diversity,
This is the evolution of species.
With the distinction between the animal kingdom and the plant kingdom,
There are doors, classes, orders, families, genera and species.
Unfortunately, Darwin was trying to find the microscopic mechanism of heredity.
1865 expounds Mendel's law of genetic separation and combination.
Mendel's experiment on pea planting turned out to be exactly what Darwin had expected.
However, Mendel was buried for 30 years because of poor communication channels at that time.
Darwin did not specifically discuss the origin of human beings in the Origin of Species.
He just hinted at the conclusion:
The improvement of intelligence and intelligence evolved step by step.
The process of human origin will be clarified sooner or later.
Later, in The Origin and Sexual Selection of Human Beings,
Darwin predicted that,
Gorillas and chimpanzees are close relatives of human beings.
Africa may be the same habitat for early apes and their close relatives.
Compared with Asia and Europe, Africa is relatively backward.
Darwin's bold prediction,
Now it seems that,
Not only accurate but also revolutionary.
Six million years ago, humans and chimpanzees parted ways.
Archaeological fossils and DNA research reveal the context of evolution.
From Australopithecus 2.5 million years ago to homo habilis 2 million years ago,
From Homo erectus 654.38+0.5 million years ago to Homo sapiens 500,000 years ago.
On the African continent, Homo sapiens is scattered in many groups.
However, only one group left Africa 50,000 to 60,000 years ago.
They first flocked to Europe and East Asia,
And spread all over the world.
Today, except Africa,
Almost all Eurasia, Americans and Australians,
You can find the same ancestor through genome testing—
That is, the group that came out of Africa.
On the contrary, Africans today,
Their ancestors belonged to different groups,
Their genome data,
There are great differences between regions.
The common DNA of modern humans,
More important than the subtle differences between them.
The word "modern human",
Equivalent to all human beings on the earth today.
