What is the XMCNC?
In nature there are often mechanisms, strategies, relationships and rules that seek efficiency, optimization, and the exchanging of resources. Mutualism is a concept in biology that describes the interaction between organisms of different species where each individual obtains a benefit.
This is precisely the reason for being of the Natural Science Museums Network of Catalonia (XMCNC): a union of museums in which everyone contributes so that everyone can benefit.
