Exploring Lifespan, Reproductive Span, and Progeny Size in Various Organisms

This chapter delves into the correlation between reproductive span, lifespan, and progeny size across different organisms, discussing a student's study on these factors. It examines how smaller progeny that are easier to deliver may lead to longer lifespans and touches on the role of grandmothers in aiding child care for humans. The discussion also covers the biological aspects of reproductive aging, the impact of menopause on aging, and the complexities of hormone replacement therapy for women compared to potential dangers of self-administering testosterone for men.
