Researchers found that among mammals, faster growth corresponds to shorter lifespans, suggesting a trade-off between energy allocated for growth versus maintenance.
The high metabolism associated with rapid growth leads to stress, which is believed to accelerate aging. However, that's not the entire explanation behind this phenomenon.
Emerging findings indicate that energy allocation to maintenance does not always equate to superior stress resistance in species, complicating our understanding of growth and longevity.
The energy cost of producing biological materials, or biosynthetic cost, plays a critical role in determining the lifespan of organisms, adding complexity to growth-longevity relationship.
