What is the Connection Between Chimpanzee and Human Chromosomes?

NGSS Phenomena: A baby chimpanzee falling asleep on its parent.
A baby chimpanzee falling asleep on its parent. I bet you never look like this in class...
Chimpanzees have been the subject of a lot of scientific research, because they're so genetically similar to humans. In the below image, wee see a comparison of the Chimpanzee and Human chromosomes.


Chimpanzees have 24 pairs of chromosomes and Humans have 23 pairs of chromosomes. It's been theorized by scientists that Human chromosome two is a combination of the chimpanzee chromosomes 2a and 2b.
NGSS Phenomena: The 23 pairs of human chromosomes are shown at the top and the 24 pairs of chimpanzee chromosomes are shown at the bottom. The 2nd and 3rd chimpanzee chromosome are about the same size as the two halves of the 2nd human chromosome.
