I am attempting to create my first 3D character just for practice. Being one of my first 3d models I going through the learning curve needless to say. In doing so I find myself creating many extra vertices. Where we will say 10 vertices on a rounded shape are spaced out on the equator and on the other north pole end of the edges they are very close. The close end could all be one vertex. Is it possible to say merge all points to one point and delete the rest?
There is a merge tool. Select the vertices you want to merge. Press ALTM (or M for Blender 2.8)
There are a few options:
At First, or Last will merge the points depending on the order in which the vertices where selected.
At center. will merge the vertices at the center of all selected vertices.
At cursor will merge the selected vertices where the 3D cursor is.
I recommend you read this page of the blender manual for this and other ways to deal with Deleting and Merging
You can automatically merge vertices that are very close to each other (within a given distance).
