## Emergence
**Emerges from:** [center](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-center.location), [part](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-part.relation), [usual](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-usual.common), [use](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-use.application)

**Through:** the center and a part together are the part that is most used

**Novel properties:**
- central prominence
- highest usage frequency
- functional dominance

## Examples

- In the human brain, the cerebral cortex is the main structure responsible for processing sensory and motor information. *(biology)*
- The Linux kernel is the main component of most Unix-like operating systems, managing system resources and hardware communication. *(computing)*
