Chromosome 2: the core difference between human and apes?

There are only 30,000 to 50,000 species of human genes, and even no more wheat and maize. The results of the whole genome sequencing of many species also show that the difference in the number of genes does not contribute much to the structure of the species, so if the number of genes Start looking for differences between humans and other species, the results must be wrong.

In 1921, an American physician named Theophilus Peinte, who looked at the microscopic observation of several psychiatric patients with self-flagellation, found that the number of chromosomes in the sperm cells of only one set of genomes seemed to be 24 .30 years later, people use better instruments, clearly see the human chromosome is only 23 pairs. At the time, it was a shock to the discovery of the religious community, because at that time all the ape suborder animals, the number of chromosomes are 24. And before the legend of the ark of the blood is 24 pairs. 80 years, due to the development of karyotype analysis technology, people and primates can be a detailed comparison of chromosomes, found almost all of the chromosome can only one, only the human chromosome 2 looks completely apes two medium size Of the chromosome after the end of the fusion (Roche translocation) of the new product! This is similar to the chromosome of the 64 chromosome and the 66 chromosome of the Przewalski's gene differences.
