Extra Free Mod

So today during west civ, Mr. Schick thought that we only had mod 2 for the class but we actually had 2 & 3 so we had mod 3 off! But before that, we got our textbooks for class and took notes. My textbook is in really bad condition which sucks but I just hope I don't lose it! Anyways, here are the notes from todays class:

• Prehistoric Era
• the origins & ages of humans
• 200,000 - human species emerged from Southwestern Africa
• 14,000 - world wide human race existed
• Paleolithic age (earliest era - stone age)
• Neolithic age (marked by using tools - new stone age)
• Initially, humans were part of migratory groups which hunted, fished & gathered.
• Ag. Revolution (Neolithic Revolution)
