Information about giant pandas

Giant pandas are chubby, like bears, with round heads and short tails. Head and trunk length 1.2- 1.8m, tail length 10- 12cm. The weight is 80- 120 kg, and the maximum weight can reach 180 kg. Pandas are slightly heavier, and males are generally slightly larger than females.

The head and body are black and white, but black is not pure black, and white is not pure white, but brown in black and yellow in white. The Qinling area is large, with rough body hair and slightly brown belly hair. Minshan (especially Qingchuan Pingwu) is smaller, with thinner body hair and less brown belly hair, but Liangshan is not small.

Second, living habits:

Giant pandas spend half their eating time every day, and most of the rest time in sleep. In the wild, giant pandas sleep for 2-4 hours between meals. Lying flat, lying on the side, prone, stretching or curling are their favorite sleep styles.

The cutest characteristics of giant pandas are chubby body and slow walking style. This is because they live in an environment with sufficient food and no natural enemies, and do not need to act quickly.

Giant pandas are good at climbing trees and love to play. Climbing a tree is generally a way for the weak to avoid the strong when approaching the marriage proposal period, or avoiding danger, or meeting each other. Pandas sometimes go down to valleys, string into houses in small villages or mountain villages, use pots and pans, especially round utensils, as toys, and then discard them in Shan Ye after playing.

Third, identity.

More than two thousand years ago, in the book Erya in the early Han Dynasty, it was recorded that "tapirs are black and reject bamboo". Sima Xiangru, a famous writer in Han Dynasty, listed nearly 40 rare animals raised in Shanglinyuan, Xianyang at that time, and the giant panda ranked first, which shows that the giant panda was regarded as a precious and famous animal at that time.

With the increasingly extensive friendly exchanges between China and people all over the world, the giant panda frequently visits as a friendly messenger, causing a sensation all over the world. Many countries are honored to receive giant pandas from the government of China. The giant panda, like a bright pearl, has added luster to China's zoos in these countries.

The giant panda "Lan Lan" presented by the government of China arrived at Ueno Zoo. In the first nine months, as many as 300 thousand people visited every day, forming a "panda fever"

Evolutionary history

Giant pandas have a long history. The fossil of Hong Shi Panda, the oldest panda member, was unearthed in Lufeng and Yuanmou, Yunnan, China, with a geological age of about 8 million years ago in the late Miocene. In the long-term harsh competition for survival and natural selection, many contemporary animals have become extinct, but the giant panda is strong and in an advantage, and has been preserved as a "living fossil" to this day.

The ancestor of the giant panda is Lufeng Giant Panda. The standard Chinese name of the giant panda is actually "panda", which means "bear like a cat". This is the earliest panda, which is mainly carnivorous and evolved from a bear-like animal. The main branches of Eocene pandas continued to evolve in central and southern China. One of them appeared in the early Pleistocene about 3 million years ago and was smaller than a panda. Judging from its teeth, it has evolved into an omnivore and an egg-laying bear. Since then, this main branch has spread to the subtropics, and fossils have been found in North China, Northwest China, East China, Southwest China, South China and even Vietnam and northern Myanmar.

In this process, the giant panda adapted to the life of subtropical bamboo forest, gradually became bigger and lived on bamboo. The giant panda reached its peak in the middle and late Pleistocene 500,000-700,000 years ago. Giant pandas in life have well-developed molars, and their claws have a "thumb" in addition to five toes. This "thumb" is actually a specialized formation of a wrist bone, scientifically called "radial sesamoid bone", which mainly plays the role of holding bamboo.

Fossils show that the ancestors of giant pandas appeared in the early Holocene 2-3 million years ago. Hundreds of thousands of years ago, it was the heyday of the giant panda, belonging to the saber-toothed elephant paleontology. The giant panda's habitat once covered most of the eastern and southern parts of China, from Beijing in the north to southern Myanmar and northern Viet Nam in the south. Fossils are usually found in temperate or subtropical forests at an altitude of 500-700 meters. Later, animals died out in the same period, but the giant panda has survived to this day, maintaining its original ancient characteristics.
