Turns out, choanoflagellates—our tiny marine cousins—have been coordinating their moves with electrical signals long before animals showed up. 

Who knew evolution had a prequel?

Researchers found these microscopic colonies use voltage-gated calcium channels, the same system neurons rely on today. 

Think of it as a primitive group chat for cells.

This discovery rewrites the playbook on how life leveled up from single cells to complex creatures like us. 

Evolution’s early days? Absolutely wild.
