Why de-extinction scientists cannot never revived mammoths?

More about the book

The narrative explores the scientific ambition to resurrect extinct giant animals, like dinosaurs and mammoths, through genetic manipulation. It highlights the misconception that modern conditions, including Earth's gravity, would support the survival of these colossal creatures. The text argues that current mammals cannot exceed the size of elephants due to metabolic constraints, suggesting that attempts to recreate such large beings would ultimately fail. The book delves into the biological limits of size and the implications for species revival efforts.
