"Ants solving a geometric problem and it's amazing."
This is a great example of 'emergent phenomenon':
- None of the ants understand the problem they're solving.
- None of them can see the whole shape.
- A series of small decisions or rules add up to something with a new layer of complexity.

The rhizarian testate amoeba that I shared yesterday makes its shell out of intricate, self-constructed glass scales. Other testate amoebozoans in the same environment make their shells out of debris (left) or food (right). These are interesting examples of convergence! #protistsonsky #protistaday
