The word "history" usually means the history of the human race.  However, I am using it in its most general meaning, namely the study of the past.  We actually cannot see the past, but we can see the objects that have been the result of past processes  - which have evolved differently.  So studying artifacts and natural processes is the notion of history that I am connoting.  So, besides human history, the fields of anthropology, archeoclimateology, archeology, astronomy, cosmology, paleontology, etc. are included in "history."
