Explore the continuation of evolutionary theories that explain the aging process through the lens of natural selection's declining influence in this 39-minute lecture. Delve into how evolutionary biology provides frameworks for understanding why organisms age, examining the mechanisms by which natural selection's effectiveness diminishes with age and contributes to the deterioration of biological functions over time. Analyze the theoretical foundations that connect evolutionary pressures to the aging phenomenon, investigating how reproductive success and survival strategies influence the timing and patterns of senescence across different species. Examine the scientific evidence supporting these evolutionary explanations and consider how these theories contribute to our broader understanding of aging as a biological process shaped by millions of years of evolutionary history.
