TED-ED: Why do animals have such different lifespans? - Joao Pedro de Magalhaes

The video explores the variability in lifespan across the animal kingdom, highlighting factors such as environment, size, and genetics that influence aging. It explains the biological process of aging, driven by cell death and dysfunction, and how different species adapt to their environments. The video also discusses human life expectancy, noting our ability to extend it through managing environmental and nutritional factors.

What are some factors that contribute to the differences in aging patterns among various animal species?

How does the environment influence the lifespan of certain species, such as the Greenland shark and the Arctic clam?

In what ways do size and body mechanics affect the longevity of small animals like worms and flies?

What evolutionary adaptations do larger animals have that contribute to their longer lifespans?

How has human life expectancy changed over the last century, and what factors have contributed to this change?
