The video explores the longevity of Methuselah, a bristlecone pine, and other extremophiles. Methuselah thrives in the harsh White Mountains due to adaptations like slow growth and dense wood, which protect it from threats. Its unique internal structure allows it to survive damage. Other extremophiles, such as tube worms, Greenland sharks, and Welwitchia plants, also owe their long lives to their extreme habitats, which reduce competition and slow aging processes. The secret to longevity often lies in adapting to extreme environments.

What is one reason Methuselah, the bristlecone pine, can live for thousands of years?

• It grows rapidly in its environment.

• Its wood is too dense for pests to penetrate.

• It is located in a tropical rainforest.

• It has a high water requirement.

How do bristlecone pines survive damage from wind and lightning?

• They have a single nutrient flow system.

• They regenerate their entire structure quickly.

• Their bodies are divided into sections with independent nutrient flows.

• They grow new branches immediately after damage.

Why do bristlecone pines face little competition in their habitat?

• They are the only trees that can survive in cold climates.

• Their seeds can germinate in high pH soil.

• They have a rapid growth rate.

• They grow in nutrient-rich soil.

What is a common trait among Earth's oldest organisms?

• They reproduce quickly.

• They inhabit extreme environments.

• They have fast metabolisms.

• They thrive in moderate climates.

How do Greenland sharks achieve their long lifespans?

• By eating a diverse diet.

• By living in warm waters.

• Through a fast-paced lifestyle.

• By having super slow metabolisms.
