Evolution Timeline - From first life-forms to Homo Sapiens

The Theory of Evolution is not a mathematical fact but it is a scientific theory.

A scientific theory originates as a hypothesis, is proven once, then tested by a multitude of peers who come to the same conclusion and is well supported by an abundance of facts.

Some people claim there is substantial debate among scientists about its validity. This is simply not true.

Why would people want to prevent our progression and understanding of where we came from? Why would people argue against something that is no longer up for debate? Why would people hate something that's basic principles have lead us to medical breakthroughs in Antibiotics?

I think its because people need to feel safe and comforted in this crazy world, and the only answers previously had been supplied by the superstitions of the past.

This is no longer the case, the answers we have been given are wonderful, they are incredible, we are part of something very special. Each and everyone of us has an ancestral line that goes back 3.5 billion years. That's this many zeros. 3,500,000,000.

Evolution Timeline

The page indicates the time line of evolution on our 4 billion year old planet.

Pay attention to the bottom scroll bar on the page for an indication of the scale.

• The lines on the background indicate inches and feet.
• 1/20th in. = roughly 100 thousand years. (108,000)
• 1 inch = about 2 million years. (2,160,000)
• 1 foot = about 26 million years. (25,920,000)
• The whole page is about 135 feet wide, almost half a football field, representing 3.5 billion years. (3,500,000,000)

One of the things that I am most amazed about is how long the dinosaurs endured on earth, and how briefly humans have lasted, so far.
