Final answer:
Diphyodonty is a process of developing two sets of teeth during the lifespan of some mammals which starts with the formation of 'baby' teeth that are eventually replaced by permanent 'adult' teeth. This is an important survival adaptation ensuring effective food chewing throughout life.
Step-by-step explanation:
The process of forming two sets of teeth during the lifespan of some organisms is referred to as diphyodonty. In mammals, this typically involves the development of a set of deciduous or 'baby teeth' that are later replaced by a set of permanent or 'adult teeth'. This process begins in fetal life where the 'milk' or 'baby' teeth (deciduous) are formed first and then shed in a sequence determined genetically. They are replaced with permanent teeth. The presence of two generations of teeth in the life of mammalian species is an important adaptation for survival. For your essential needs, two-generation development of teeth has evolved to permits effective food chewing throughout life providing nutritional benefits to ensure growth and development.
