Internal users will require a CAL which is about $100 per user. A forecast of the number of users will be used for Capacity planning for your SharePoint farm. Each server will require a server license. So the number of users may increase the cost of the server licensing.
Another example of convergent evolution is the overall body structure of the shark and the dolphin. A shark is a fish and a dolphin is a mammal. However, their body shape and how they move through the ocean is very similar.
Many species have similar traits because they are descendants of a single common ancestor. These species developed from a single source and are related to a certain degree despite their current differences. The traits they share are known as homologous structures.Homologous structures are similar in structure and function because they originated from the same ancestor long ago. Species may also have similar traits even though they are not related to each other.This usually results because the species live in similar environments and fill similar ecological roles. The structures in this case are known as analogous structures.The process that brings these traits forward is called convergent evolution. Convergent evolution is natural selection that favors the same type of structure in different ancestors.owever, even though these wing structures serve the same function for these different animals, the bone structures, wing coverings (such as feathers, scales, hair, etc.), shapes, and sizes are quite different. Another example of an analogous trait is fins.
