Evidence of the origin of humans from animals is the similarity in the development of their embryos. In the human embryo, the notochord is formed first, the circulatory system is the same as in fish (two-chambered heart, one circle of blood circulation), gills and tail are laid. Also, the embryos develop the rudiments of several pairs of mammary glands, the whole body is covered with hairy down. All these signs indicate a relationship between humans and animals. By the time of birth, with the correct development of the embryo, they disappear.
