Human Life Cycle

The human life cycle involves the following stages:

  1. Mating (sexual reproduction)
  2. Fertilistion and embryonic development. At this time, a baby is growing inside its mother鈥檚 womb, this takes 40 weeks
  3. Infanthood. At this stage, you learn to walk and talk
  4. Childhood growth
  5. Adolescence
  6. Adulthood. Further sexual reproduction can take place at this stage and so the cycle continues
