The Brights' it is unique. They describe it this way:
"Earth and Life: changes over time" is a pictorial representation of evolution from the “Big Bang” to current times. The unique feature of this poster is that it combines physical science and life science events on the same time scale. The viewer will be able to see connections not seen in other timelines of evolution. Educators will be able to show students the impact of physical and geological events on the evolution of life, while others can enjoy the grandness of the presentation and gain a new perspective of the processes involved in our changing world.
