"The Origin and Development of Humankind" The Origin of Man PPT Courseware 2

Guess: What animal walks on four legs when it is young, then walks on two legs, and then walks on three legs when it is old?

Let’s talk about it: Where did the earliest people come from? What myths and legends do the students know?

Observe the picture of apes and answer the questions:

1. Where on earth are these great apes distributed today? What do their lifestyles have in common?

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

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

What do the lifestyles of modern great apes have in common?

1. They all rely on obtaining fruits, buds, insects and other food from the forest to survive;

2. No ability to make tools and improve the living environment;

3. Inability to communicate in language and text like humans do

Reasons for the rapid increase in the number of humans

Human beings have the ability to invent and create various sciences and technologies, which have enabled humans to continuously strengthen their ability to adapt to the natural environment, transform the natural environment, improve living conditions, and use medicine and health to strengthen their own health care. All these have contributed to the rapid increase in the number of humans.

Reasons for the dwindling number of great apes

1. Great apes do not have the ability to invent and create technology;

2. Human development of forests destroys and pollutes the environment

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

think about it

Geologists tell us that 10 to 20 million years ago, the earth's crust moved violently, and mountain ranges such as the Himalayas and the Alps appeared one after another. In East Africa, the largest rift valley in the world was formed, stretching from Mozambique in the south to Jordan in Dacia in the north. The river valley is more than 6,000 kilometers long. At that time, the climate on the earth also experienced drastic changes. Under the influence of huge changes in terrain and climate, part of the original tropical jungle in the East African Rift Valley has turned into savanna. Think about it, a large amount of forest has been turned into a savanna. What impact will it have on the forest apes there?

Answer: As a result, some forest apes were forced to live on the ground.

Let’s talk about it: How did the forest apes develop in the direction of humans? [Think about changes in the environment, changes in movement patterns, use of tools, changes in brain capacity, and the production of language.]

2. Human development

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: not being able to use tools, using natural tools, making and using simple tools, making and using complex tools (language is produced in labor)

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

1. The Origin of Humanity

2. Causes: Changes in the environment and changes in its own morphological structure

3. Evidence Fossil evidence

�1�The "Lucy" era�3 million years ago�

�2�Era of "East Africans" �1.75 million years ago�

4. Place of origin: Africa
