From weeks to centuries: the biological mystery of animal lifespans
In short: Why does a microscopic worm live for weeks while a whale survives for centuries? This video explores the fundamental mechanics of aging and the factors that dictate how fast life unfolds across different species.
The video examines the vast disparity in longevity, contrasting the short life of the C. elegans lab worm with the 200-year lifespan of the bowhead whale. It seeks to define what 'aging' actually means at a biological level and why the pace of this process varies so drastically across the animal kingdom.
