A timeline of life.... 4.5 Billion years of evolution

Evolutionary Events and Geologic Time (Deep Time)

Once you've calculated the number of years  between each of the evolutionary events and the distance between each event on your timeline, create an accurate timeline including the number of MYA (millions of years ago) each event occurred.

Use the following images and links (
and others you find on your own) to find images to use as guides for drawing a representative diagram of each event on your timeline. (I included the first few which are more difficult to find... you can find the others on your own.)

Be careful to organize your timeline so you have enough room to draw images for each event... this is easy at the beginning, but very difficult toward the present day... events happen faster and faster toward the present.
