Charles Robert Darwin (1809-1882) was a British naturalist and the founder of the theory of evolution. As a naturalist, he traveled around the world for five years on the naval exploration ship "Beagle". He observed and collected a large amount of materials on animals, plants, geology, etc., and after summary, sorting and comprehensive analysis, he formed a biological process. the concept of. In 1859, he published the book "On the Origin of Species", which comprehensively proposed the theory of evolution based on natural selection.

2. Comparison between great apes and modern humans

Discussion: 1. In what aspects are great apes fundamentally different from humans?

2. Where are great apes distributed today? How is the lifestyle?

3. Why is the number of great apes decreasing while the number of humans is increasing?

Why did a branch of forest ancient apes evolve into humans?

1. Judging from the skeletal fossils of the girl "Lucy", the hip bones of her pelvis were wider and the femurs of her lower limbs were thicker, which are similar to modern humans. Imagine how she moves?

2. What did “East Africans” do with the rocks shown? Judging from the shape of the stones, what abilities do "East Africans" already have?

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

3. In the harsh struggle with nature, forest apes evolved into humans. The same forest apes also evolved into great apes. Can modern apes evolve into humans?

cannot. Modern great apes have adapted to their current environment and cannot evolve into humans.

4. Cytochrome C is a protein with about 110 amino acids. Using amino acid sequence determination to analyze the number of differences between the amino acids in cytochrome C of various organisms and humans is as follows:

5. Cao Zhi wrote a poem criticizing his brother Cao Pi for persecuting him: "The leaves are burning under the cauldron, and the beans are weeping in the cauldron. They are born from the same root, so why rush to fry each other!" Man and ape have the same ancestor, how should humans treat rare and endangered species? What about living apes?

Cao Zhi compared himself to a bean and his brother to a beanstalk. The beans in the cauldron said to the beanstalk at the bottom of the cauldron: "We grew from the same root. Why are you so eager to torture me and boil me to pieces?" This poem uses vivid metaphors to illustrate that brothers are born into one body like siblings, so they should not kill each other. So, modern great apes are close relatives of humans and members of the biosphere. They also have the right to survive and reproduce on the earth. We should strengthen our protection. We should increase the protection measures for modern great apes and other wild creatures, such as strengthening publicity, implementing the Wildlife Protection Law, establishing nature reserves, protecting the forest environment where they live, and resolutely stopping all behaviors that damage their survival.
