edit: The reason I find it an odd term is because human ancestry literally doesn’t follow a line. It always branches off, even if only to just include two parents. It’s a tree like structure, a line would misrepresent it

It’s just different use cases. A tree would show relations to the individual, a line just proves they descended from a particular person. Applications of it might be a bit outdated, but I don’t think there is any more reason to show relations in a tree than “oh, that’s neat”.
