Think of it like a tree. You have the initial virus as the trunk, and then you have branches off that trunk (delta, omicron, etc), and then you have branches off of the branches, and so on and so on.
The most dominant version of coronavirus floating around is XBB.1.16, known as "Arcturus.” Arcturus is off the omicron branch of the evolutionary tree.
