It is the increase in chromosomes in chimpanzees and the decrease in chromosomes in humans

Chromosomes are just tools that carry genetic information.

The essential difference between organisms is still due to the difference in genes.

In 2003, when the Human Genome Project was nearing completion, biologists, while hailing the achievement, were surprised to find that the number of genes in humans was less than originally estimated, yes, only about 10,000, when it was thought that there should be 100,000. In comparison, a very simple organism, nematodes, also has 20,000 genes. Arabidopsis plants have slightly more genes than humans, while rice has twice as many genes as humans.

Scientists believe that the way the genome works should be more flexible and complex than previously thought, and they are exploring the molecular mechanisms by which fewer genes can do more.

Humans and chimpanzees share a common ancestor, but we have one less pair of chromosomes, why is that?

How many pairs of chromosomes do humans have? Everyone can blurt out 23 to 46But few people wonder why, about 5 million years ago, they parted ways with chimpanzees. However, modern chimpanzees have 24 pairs of chromosomes, a full pair more than modern humans.

In addition to chimpanzees, other great apes such as bonobos and gorillas also have 24 pairs of chromosomes. This also means that humans have lost a pair of chromosomes in the last 5 million years. So, how do we lose an entire pair of chromosomes?

If you think about it, it can be unsettling.

Because genetic mutations and chromosomal mutations often mean all kinds of terrible genetic diseases, about chromosomal abnormalities, I am most familiar with Down syndrome. Because there is an extra chromosome 21, it is also called trisomy 21. One in every 600 babies with Down syndrome is born.

The child will have a special Down face, accompanied by various physical defects and almost inevitably mental retardation. Not only chromosome number changes, but also transient genetic mutations can lead to serious consequences.

However, in addition to these individual tragedies, the most fatal for all mankind is the inability to have offspring due to chromosomal abnormalities, which will affect the top priority of human reproduction. Since it is difficult to reproduce, how do humans lose these two chromosomes? All of these questions also give conspiracy theorists a chance.

They believe that the difference in the number of chromosomes between humans and apes is an insurmountable gap in evolution that could upend the origin of species. How did the first human ancestor with 46 chromosomes survive and produce fertile offspring, they ask?

In addition, conspiracy theorists painstakingly calculate the probability of success and, on the basis of a "very small possibility", declare evolution bankrupt and introduce creationism, but if you think about this biological question, the answer is obvious. Chromosomes are made up of DNA and proteins, and proteins are just carriers of genes. In fact, what is more important is the information that chromosomes carry.

As long as there is the right amount of genetic material, how to arrange and combine this genetic material is not as important as imagined.

I don't think so. Mainly because he didn't have human intelligence, and they didn't know how to drill wood to make fire.

Because it is possible that humans also evolved from orangutans, orangutans will have two more chromosomes than humans.

Humans and orangutans are not the same species, so it's normal for the number of chromosomes to be different. Although humans evolved from orangutans, in the process of gradual evolution, the two have become reproductively isolated. The 2 fewer chromosomes that humans have than orangutans may have been lost during evolution.

Because humans and orangutans have evolved in different directions, humans have evolved and optimized their chromosomes, and all humans have forty-six chromosomes, while orangutans have forty-eight.

After the German scientist Walser Dleming discovered the chromosome, he compared humans and orangutans, and found that there were about 24 pairs of chromosomes in the body, while there were only 23 pairs of chromosomes in humans. This doesn't make sense!

24 pairs! Chimpanzees are genetically almost identical to humans! There is only a difference! But it is this that creates two species! Other species of orangutans are similar! It's just that the closest thing to a human being is a chimpanzee!

Probably not. Chimpanzees and gorillas are different organisms that, despite having the same number of chromosomes, they are reproductively isolated and cannot produce offspring, and even if they do, they are infertile .

Hope the answer solves your doubts.
