Furthermore, humans have their own unique life cycle stages. There are four life cycle stages common to all great apes: “infant,” “juvenile,” “adult,” and “old age.” In addition to these, only humans have a “childhood” 1 stage between “infant” and “juvenile,” and also an “adolescent” 2 stage between “juvenile” and “adult.”
In addition, as we will discuss later, the “long post-menopausal age” is also unique to humans.
1The stage in which humans have weaned, but cannot yet eat the same solid foods as adults.
2The stage in which humans have reached sexual maturity, but have not yet actually started breeding.
