<u>How many years are represented on the timeline?</u>
You can find the amount of years this shows by subtracting the oldest date/time from the most resent time shown.
(but I already saw that you said u know it, so :p)
<u>What would you identify as significant events?</u>
Me, personally, I would say the event that has changed the world we know today the most.
so, I guess I would say humans moving out from Africa, and spreading, or early Egyptians figuring out farming.
<u>What parts of the world are included?</u>
The parts of the world I see in this are Egypt, Africa and Turkey. I can't find anymore.
<u>What similar events do you see?</u>
Spreading from Africa and developing turkey both have to do with humans moving from one place to another, or creating a new place to live.
