What development is called intrauterine? What is its advantage over development taking place in the external environment?

Intrauterine development takes place inside the mother’s body. This is typical of mammals. For example, a person. In us, the period of intrauterine development lasts nine months. The advantage of this way of development is that the offspring are well protected. Also, through the mother’s body, all the necessary nutrients enter the developing fetus. Therefore, the offspring develops quite quickly. After birth, the body continues to develop. Development ends with the onset of the death of the organism.
