Question

Identify the major stages (and phases within them) of human life history. Explain the significance of each phase. Define the commencement and end of each phase (when appropriate).

Answer 1

The major stages of human life history include germinal stage, embryonic stage, fetal stage, infancy, childhood, adolescence, and adulthood with different characteristics and developments in each stage.

Step-by-step explanation:

The major stages of human life history include the germinal stage, embryonic stage, fetal stage, infancy, childhood, adolescence, and adulthood.

The germinal stage begins at fertilization when the sperm and egg cells combine to form a zygote. The embryonic stage follows, during which major organs and systems develop. The fetal stage is marked by continued growth and maturation of organs.

Infancy refers to the period from birth to the first birthday, childhood spans from toddler years to pre-puberty, and adolescence is the stage of rapid physical and psychological changes during puberty. Finally, adulthood is the stage of maturity and independence, which can be further divided into early adulthood, middle adulthood, and late adulthood.
