Two organisms wich live at the same time cannot be ancestors of each other. Why not?

False.
Your grandmother is living at the same time as you, and is an ancestor of you.

They cannot be ancestors of each other because the term ancestor refers to a generation that came before. Thus, two organisms living at the same time cannot be ancestors of one another. Good luck!
