Darwin's Theory of Evolution: The common ancestor of modern apes and humans is forest apes.

In 1859, Darwin published "The Origin of Species". In this book, he hinted that his views would provide important ideas and clues to the study of human origins. Later, in other works, he pointed out more clearly that humans evolved like other animals, and speculated that humans are related to gorillas and chimpanzees. At that time, many scientists firmly believed in creationism, and as a result, supporters of Darwin's evolutionary ideas and supporters of creationism launched a heated debate.

Gibbons are the only living great apes in my country. Together with orangutans, gorillas, and chimpanzees, they are known as the four major great apes. They are advanced primates after humans.

Gibbons are the smallest of apes and the fastest and most agile. There are 5 species of gibbons in my country, and they are all first-level protected animals in my country.

There are currently 7 species of gibbons in the world, among which the black gibbon, white-browed gibbon and white-palmed gibbon live in my country and neighboring countries, and have been listed as first-level protected animals.

Orangutans are Asia's only great apes, now found only in the steamy jungles of Borneo and Sumatra.

The two species of orangutan are outstanding in many ways. They are the world's largest arboreal and slow-reproducing mammals. Orangutans are considered social recluses, establishing regional patterns that recall early human cultures.

Gorillas are the largest animals in the order of primates. They live in the jungles near the equator of the African continent and eat a vegetarian diet. 92% to 98% of the gorilla's DNA sequence is the same as that of humans, making it the closest living animal to humans after the two species of the genus Chimpanzee. In the past, gorillas were considered to be fantasy creatures.

Question exploration:

1. Who is the common ancestor of modern apes and humans? In what areas are they mainly distributed?

2. What kind of life do modern great apes live?

3. The number of humans is increasing rapidly, while the number of great apes is decreasing. Why is this?

4. Great apes do have many similarities with humans in terms of morphological structure, but in what aspects are they fundamentally different from humans?

focus

The fundamental difference between modern apes and humans is mainly that

1. Different modes of exercise. Apes walk mainly with arms; humans walk upright.

2. The ability to make tools is different. Apes can use natural tools but cannot make them; humans can make and use a variety of simple and complex tools.

3. The degree of brain development is different. The capacity of the ape brain is about 400ml, and it has no language and writing ability; the capacity of the human brain is about 1200ml, and it has strong thinking ability and language and writing ability.

ANALYSE information

1. How did forest apes evolve into humans?

2. Many early ancient human fossils have been found in the Great Rift Valley of East Africa. What does this mean?

In what aspects did human beings gradually change during their origin and development?

Mode of movement: semi-upright walking, upright walking

In terms of labor: unable to use tools, using natural tools, making and using simple tools, making and using complex tools

In terms of dressing: being naked, knowing how to keep out the cold and cover up shame

Other aspects: Brain capacity becomes larger, functions are enhanced, and language is produced...

Distinguish between facts and opinions

1. The ancient human fossil "Lucy" was discovered in Africa.

2. "Lucy" lived 3 million years ago.

3. No ancient human fossils from 2 million to 3 million years ago have been found in other areas.

4. There are no ancient human fossils from 2 million to 3 million years ago in other areas.
