How the Earth was Made (A brief DVD review)

I first watched this show on the History channel at the beginning of last winter and liked it immediately. So I pre-ordered the DVD on amazon right away. It arrived last week and is currently making the rounds in my office!

Many a time, I have visualized how our precocious planet formed and evolved based on paleobiological evidence. I always get a feeling of euphoria whenever I imagine a pristine Earth with dynamics that have been changing over mind-numbing time scales. Well, the graphics in this show come pretty close to my own imagination.

The playback, divided by mostly uneven time segments, starts at around 4.4 billion years ago and eventually works its way to the last ice age before briefly dwelling on the planet's future. There is a time slider that briefly appears at the start of each time segment. Yes, dinosaurs are mentioned and shown but only briefly. Yup, stromatalites are in there as well along with Trilobites. It should be noted that the Cambrian Explosion and the Carboniferous are mentioned. For some reason, I was surprised to learn that granite first formed several billion years ago.

Other subjects discussed in depth include plate tectonics (continents, mountains, etc.), land inhabitation by flora and marine animals and super-volcanoes. The DVD ends with a bunch of scientists dwelling on the future of Earth. I decided not to read too much into their predictions as I won't be around if/when what they predict happens.
