The Deadliest Ice Age Ever

The video explores the history of life on Earth, focusing on major extinction events. It discusses the appearance and diversification of early animals, the impact of Ice Ages, and the mass extinction of marine species. The video highlights the role of climate change in these events and raises questions about the survival and extinction of certain species. It emphasizes the need for further research to uncover the mysteries of past extinctions.

What significant event occurred around 550 million years ago?

• Track marks of an ice sheet's expansion

• Fossilized dinosaur bones

What was the primary cause of the first major extinction event on Earth?

• An Ice Age

• An asteroid impact

• A massive volcanic eruption

Why is the Ice Age that occurred 450 million years ago particularly puzzling to scientists?

• It was the longest Ice Age in history

• It led to the extinction of all land animals

• It resulted in the formation of the first oceans

• It caused more extinctions than any other cold period

What remains a mystery about the species that survived the Ice Age?

• Why they developed new body shapes

• Why they later died as seas rose and temperatures warmed
