Do they, by chance, have a geographic distribution of these types of clips as well. For example, Haplognatha primarily found in parts of Europe and North America, etc?
All of the pieces in this series and the others are amazing, as well. For anyone that hasn't checked out the rest of them, it's worth even a few minutes.
At least they're not asking you to solve math problems (e.g., Floor Square Root of 4) or rebuses...
And technically, I guess it does if you throw it hard enough...
But, maybe it this is well received, there will be a "Zombie Survival Guide: The Movie." *shudder*
