8 The “Missing Link” No such thing as a “missing link”! It’s a tree, not a stepladder! No!

9 No higher organisms. No lower organisms. All organisms “branch” from a common ancestor

11 Transitional Forms No current species evolved from any other current species! not Evolution does not work this way!
