I have been interested all along my career to find the causes of the evolution of parasite life as well as that of parasitic and free-living nematodes.
Hi @HugoMejíaMadrid, that certainly sounds interesting! Did you have a related question that is tied to ArcGIS for Excel, by chance? You've published your post in the ArcGIS for Excel Questions Board, so we want to make sure there's a GIS connection and that it's specific to that Esri product (or we can help get it moved to the right Esri product if it should be elsewhere).
