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

Unit objectives:

Understand the structure and physiology of the human body

Focus on the relationship between man and the biosphere

learning target

1. What type of animal do humans originate from?

2. What is the evolutionary process from apes to humans?

Where did humans come from?

After careful comparison of the similarities between humans and modern great apes, it was proposed that the common ancestor of humans and great apes was a kind of ancient ape - forest ancient ape.

Shown above are diagrams of four modern great apes. Please observe the picture of great apes and try to answer the following questions based on your life experience and knowledge:

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

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

3. 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.

Evolution from apes to humans

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 earth's climate 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 region turned into savanna. Think about it, if a large amount of forest turns into savanna, what impact will it have on the forest apes there?

discuss

After a long period of time, human beings have changed from the weak in nature in their childhood to the strong. Humans are now powerful enough to influence the face of the biosphere. Should humans develop and use the ability to transform nature more rationally?

Skill training – distinguishing between facts and opinions

Based on the passage on page 6, can you determine which of the following statements are facts and which are 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 to 3 million years ago in other areas.

5. Homo erectus in Asia migrated from Africa.

Comprehensive improvement

A. Modern great apes, like their ancestors, still live a mainly arboreal life in the tropical jungle.

B. Ancient humans in the "Lucy" era could already make simple tools

C. Ancient humans in the "East African" era were already able to use fire and developed language

D. Human beings’ ability to change the environment exceeds that of all other organisms, and the environment has no impact on humans.
