Stealing the entire post from P. Z. Myers at Pharyngula:
I’ve been playing with it for a while. It turns out that when you go back to Cretaceous Morris, you need to be able to swim really well, but Cambrian Morris is high and dry on a fairly small landmass (whoa, but oxygen is way down and carbon dioxide way up). You can have your own time machine, too — it’s the EarthViewer app for iPad, and it’s free from HHMI Here’s what it has:
• Data and continental reconstructions dating back billions of years
• Climate and carbon dioxide data for the last 100 years
• The ability to manipulate the globe and zoom to any location
• Track the location of modern cities back over 500 million years
• In depth features on major geological and biological events in Earth history
• Clickable details on geologic eons, eras, and periods
• Automated play modes
• An extensive reference list
• Suggestions for classroom use
• Tutorial videos
Did I mention that it’s free? This HHMI thing is pretty danged sweet.
There is no creationist/Noah’s Flood version.
No Windows version, yet, either.
Did we mention the Howard Hughes Medical Institute made this and related apps free?
