What is a criticism of the evolutionary theory of aging? Rethinking senescence

While the evolutionary theory has long provided a foundational framework for understanding why we age, recent discoveries present significant challenges. For example, the existence of species with negligible senescence prompts a critical re-evaluation of the theory's central tenets regarding natural selection's role in aging, highlighting a key criticism of the evolutionary theory of aging.

Understanding What is the Evolutionary Theory of Ageing?

While the quest for longevity is timeless, the average human life expectancy has risen dramatically over the past century. To understand the origins of this universal process, scientists turn to a fascinating field of biology to answer the question: **what is the evolutionary theory of ageing?** This concept posits that aging is not a purposeful program, but an inevitable consequence of evolution.

What is the evolutionary purpose of aging? Unpacking the scientific theories

From an evolutionary perspective, the phenomenon of aging presents a paradox: why would a process of physiological decline be tolerated by natural selection? Answering **what is the evolutionary purpose of aging** requires understanding that it is largely a non-adaptive byproduct, not a designed feature, resulting from several powerful selective pressures on an organism's life cycle.

Do humans have a long post-reproductive period? An evolutionary perspective

While most animal species reproduce until they die, humans are a significant evolutionary outlier. For women, in particular, a substantial portion of their adult life is spent in a post-reproductive state. **Do humans have a long post-reproductive period?** This phenomenon is a fundamental aspect of our life history with deep evolutionary roots.
