Document Summary
Onset at 13 vs 17 years of age; well nourished vs poor. Stress nourishment: stress can push onset of puberty earlier, parenting styles can affect onset. Mice living in a female only environment- even the exposure to odor of unrelated males can lead to early maturation: those female mice will mature earlier than unexposed females. From a biological perspective, the goal in life is to reproduce: the unfamiliar male is an opportunity to reproduce; the adaptive response is to mature more quickly, hence early onset of puberty. In canadian girls, facilitating puberty can occur in situations with: absent father homes, high levels of stress. When girls are stress, they tend to show internalized behaviours. Increased stress can also lead to increased fat content (which is related to early onset) Current environment is the best predictor for future environment. Peaceful environment -> delay onset puberty; delay sexual activity; current/future stable relationships.
