Have you ever thought about what the Earth was like in its prebiological days?

Yeah, it's fascinating to imagine a world without any living things at all.

Root Explanation

Prebiological → It is formed from "pre-" (meaning before) and "biological" (from Greek "bios", meaning life, and "logia", meaning study). The word "prebiological" refers to the state or conditions that existed before the emergence of life.

Memory Tip

Think of 'pre-' meaning 'before' and 'biological' relating to 'life' — so prebiological refers to the time before life existed.
