Eons

The format of this show is much like a series of Ted Talks. Each episode is short, something like 15 minutes and the hosts get right to the point. They appear to be professional natural historians and are comfortable with the jargon,. They deliver loads of information in a hurry. If you are interested in the natural world you will probably like this series.

In most cases the animations and visual depictions are adequate but not a lot of money is spent on computer generated graphics or animations. That's fine with me.

Each presentation is sprinkled with nerdy jokes that come off pretty well in my opinion.

This series is targeted at adults but smart teenagers could enjoy it as well.
