Hurricane Walaka Erases Entire Hawaiian Island | SciShow News

The video discusses the disappearance of East Island in the French Frigate Shoals due to Hurricane Willacca, highlighting the impact on endangered species like Hawaiian monk seals and green sea turtles. It explores the role of climate change in increasing storm severity and island vulnerability. Additionally, it covers new research on tortoise evolution, challenging the island gigantism theory by suggesting that giant tortoises evolved on the mainland before spreading to islands.

What was the primary reason for the disappearance of East Island?

• Rising sea levels

• Hurricane Willacca

• Volcanic eruption

• Human activity

Which species is most affected by the loss of East Island as a breeding ground?

• Hawaiian green sea turtles

• Laysan albatrosses

• Galapagos tortoises

• Hawaiian monk seals

What is a direct consequence of global climate change mentioned in the transcript?

• Decreased rainfall

• Higher earthquake frequency

• More severe storms

• Increased volcanic activity

What theory about tortoise evolution is challenged by recent research?

• Predator-prey dynamics

• Island gigantism

• Mainland extinction

• Climate adaptation

According to the new research, where did giant tortoises likely evolve?

• On the mainland

• In the Arctic

• On islands

• In the ocean
