Document Summary
We are formed by our genes and by our contexts, so our stories will differ. In many ways we are each like nearly everyone else on earth. Natural selection disposes us to survive and perpetuate our genes. Stability marks our development - we experience a continuous self. Continuity morphs through stages growing up, raising children, enjoying a career, and eventually, life"s nal stage. Developmental psychology - analyzes our physical, cognitive, and social development across the life span, with a focus on 3 major issues. Nothing is more natural than a species reproducing itself. Process starts when a woman"s ovary releases a mature egg. The woman was born with all the immature eggs she would ever have. Only 1 in 5000 eggs will ever mature and be released. A man begins producing sperm cells at puberty. For the rest of his life, 24 hours a day, he will be producing sperm non-stop, slowing with age.
