Are gorillas distant relatives of humans? What is the biggest difference between orangutans and huma

Gorillas are the largest primates. They live in the tropical rainforests of the equatorial of Africa. Adult male gorillas are 2 meters tall and weigh about 140,250 kg when they stand upright, and can exceed 290 kg at their peak, and about 70,120 kg for females.

Gorillas live in groups. Each group of 16 30 individuals, led by a male gorilla, has its own range of movement, usually covering an area of about 40 square kilometers. Different groups can also forage together amicably and even very kindly when they meet.

Gorillas feed on leaves, shoots, ferns, root plants, fibrous bark, and sometimes wild fruits, gorillas are actually very quiet animals, and they are also very intelligent, about the same IQ as a three- or four-year-old human child.

A distant relative of humanity.

In the past, researchers relied only on morphology. From the perspective of the similarity of limbs and organs, it seems that there is still a big gap between humans and orangutans. Finally, biologists analyzed the genes of humans and orangutans and were surprised to find that the difference between humans and orangutans was only 1%, which was mainly judged by studying the genetic material "deoxyribonucleic acid".

"DNA" is a set of maps that can explain how animals develop and grow, and how they make the various proteins they need every day, such as muscles, cells and other components. Scientists judge the difference between humans and animals by analyzing a certain protein, such as analyzing the sequence of amino acids in hemoglobin. Although the results of the experiments vary slightly from house to house, the general trend is that humans and orangutans are the most similar, followed by humans and monkeys, and humans and dogs.

Roughly calculated, humans and orangutans were the same ancestor 5 million years ago.

Is the birthplace of humanity in Africa? Gorillas and humans turned out to be relatives.

1. The body shape is different

The biggest difference between orangutans, also known as apes, and monkeys is their tails, which orangutans do not have and monkeys do, which they use to maintain balance or climb trees.

2. The proportions of the limbs are different

Orangutans have shorter hind limbs than forelimbs; Monkeys have longer hind limbs than forelimbs.

3. Different walking postures

When an orangutan walks, the fingers are bent and the back of the hand or knuckles touch the ground;

When the monkey walks, the fingers are flat and the are straight, and the palms of the hands touch the ground.

4. The growth direction of arm hair is different

Orangutan hair grows outwards horizontally or upwards; The monkey grows in the direction of the palm of the hand.

There are only approximate differences between humans and orangutans in their genetics. But looking at each chromosome, you can see a lot of differences. During a detailed analysis of chromosome 8, the joint research team found a field near the tip of the chromosome's protrusion that was quite different from that of orangutans.

The difference between this field and the orangutan is that some of the location differences are achieved. The differences in this chromosome contain genes related to brain size and genes related to immunity. Scientists believe that in the course of human evolution, chromosome 8 gradually became more different from that of orangutans, which may be the key to why humans are human.

The order of arrangement should be:

Chimpanzees, gorillas, orangutans, gibbons.

Ever since Charles Darwin created the theory of evolution, he proposed that human beings originated from.

For more than 100 years, zoologists have been studying the distinction between humans and apes from the aspects of comparative anatomy and paleontology. Through a large number of anatomical comparisons between the human body and the ape, they summarized the differences and similarities between humans and chimpanzees, gorillas, orangutans and other apes in terms of morphological anatomy, so as to classify humans into the family of humans, and chimpanzees, gorillas, orangutans, etc. Most zoologists believe that gibbons are the most distantly related to humans among the various apes in existence, followed by orangutans.

Chimpanzees and gorillas are closer to humans, but chimpanzees, gorillas and orangutans are much closer to each other than they are to humans. Such a theory of ape division has not been doubted for more than 100 years.

Commonalities between humans and chimpanzees: thumb and index finger opposite; unique expressions of joy, anger, sadness and happiness; The structure of the bones is the same. It shows that humans and chimpanzees are closely related and have a common ancestor, Australopithecus forest, which evolved.

The differences between humans and chimpanzees are: 1) Different modes of movement. Great apes are predominantly armed; Humans, on the other hand, walk upright.

2) The ability to make tools is different. Great apes can use natural tools, but they can't make them; Humans can make and use a variety of simple and complex tools. (3) The degree of brain development is different.

The ape-like brain has a capacity of about 400 ml and has no ability to speak and write; The human brain has a capacity of about 1 200 ml and has strong thinking and writing skills.
