The difference between humans and animals.

The most fundamental difference between humans and animals is that humans have the ability to think and judge independently, while animals generally do not have these two functions.

Although some primates (such as apes and orangutans) have expressions of joy, forgiveness, longing and joy and some simple expressions in some experiments, they do not have the ability to think independently. ?

Human beings have advanced ideas, thus creating culture, language, art and morality. Culture is promoted with the background of human development, and language is promoted with the background of development. Art is a form of expressing the advantages of both. It's just that morality is not an established goal, nor is it an idea that human beings must follow. This is the principle of human development and the only difference between humans and animals.

Animal taxonomists classify animals according to their various characteristics (morphology, cell, heredity, physiology, ecology and geographical distribution, etc.). ) and divide it into six main grades, namely, phylum, class, order, family, genus and species.

According to fossil research, the earliest animals on earth originated from the ocean. After a long geological period, early marine animals gradually evolved into various branches, enriching the early life forms of the earth. Prehistoric animals appeared in their respective activities before human beings appeared.

Later, they became extinct in the ever-changing living environment. However, the animals on the earth are still evolving and multiplying from low to high and from simple to complex, with today's diversity.

Scientists divide the known animals into invertebrates and vertebrates. Scientists have identified more than 46,900 species of vertebrates. Including carp, yellow croaker and other fish animals, reptiles such as snakes and lizards, amphibians such as frogs and giant salamanders, and mammals such as birds and red pandas.
