Exam 1 Review:
DNA polymerase ? involved in the replication of DNA, requires a ?primer? to initiate a new strand of DNA, faster at synthesis
RNA Polymerase ? involved in transcription of DNA to mRNA, does not require a primer to start a new strand of RNA and will stop transcription with it encounters a stop codon

The idea of change over time
was not new
Chapter 1: The Neolithic Revolution and the Birth of Civilization
Human life in the era of hunters and gatherers homo sapiens- our species, had a more developed brain and free hands with opposable thumbs also in this time their children did not develop mature teeth until well after weaning
By the end of the Paleolithic Age these advantages had made Homo sapiens a species capable of changing its environment
Paleolithic culture (Stone Age)
In late Paleolithic age
