Earth Timeline

[Kablooie]

So I tried to visualize how much time we have had to evolve on the earth.
I took the 10,000 years of human history as a basic unit and mulitiplied it to see how long it is in comparison to the history of the world.

I expected something like, if a football field represented the age of the world, human history was contained somewhere within the last yard line.

What I found out was this:

Imagine 4 football fields, end to end.
This represents the age of the world.
Each field is a little over 1 billion years long.

Single celled life appeared somewhere around the middle of the first field.

Multicellular life appears a little before the last field.

Modern groups appear in the Cambrian Explosion around the middle of the last field.

First vertebrate land animals at 38 yards from the end.

Insects and Fish at 32 yards.

Dinosaurs started around the 24th yardline.

Mammals showed up 2 yards from the back of the end zone.

Australopithicaus was around 14 in. from the goal line.

The first humans appeared about 6 in. from the goal line.

All 10,000 years of human history is contained in the last 1 millimeter, about the thickness of a dime.
