Hоminin fоssils Pick twо hominin fossil species (only hominin) thаt were covered in the lecture/module for this exаm section only (you must give informаtion for at least one from the lecture/module - for the other you can decide if you want to use the textbook or not).  Describe at least two significant characteristics, or facts about them. Structure can be something like this (two times): Hominin fossil species:   Additional (2) facts I learned about the species:
