[SOLVED] Anthropology Virtual Lab : Dating Techniques Quiz
I need an explanation for this Biology question to help me study.
Hello, please follow the instructions below carefully and answer specifically as requested. Thank you.
Your textbook discusses several dating methods with which scientists determine the age of fossils and artifacts. This Virtual Lab provides some additional information about these processes. Explore the following websites and then take a quiz on dating methods.

False
Question 2
Luminescence dating can be used to date pottery that has been fired.
True
False
Q3
Carbon 14 is not an appropriate method for dating fossils from the early stages of primate or human evolution, as these events took place millions of years ago.
