What is the similarity between humans and animals?

The similarity of humans with animals lies in a single structure scheme. Human and animal organs are characterized by the same organs and organ systems (circulatory, respiratory, excretory, digestive, nervous, genital, etc.). In addition, the similarity of humans with animals is confirmed by the presence of rudiments and atavisms. A person has more than 90 vestigial organs: tailbone, appendix, wisdom teeth, third eyelid, etc.
