Yum, or rather rpm, has no pre-imported keys at all. Every one of them 
is installed as a resutt of some post-installation action, such as 
running a "yum update". The keys are supplied out-of-the-box in the 
fedora-release package, but they're not pre-imported into the rpm database.

It's possible that, for whatever reason, the evolution-data-server 
package was the first one yum tried to check the GPG signature of when 
you did the update, since all of the updates packages should be signed 
by that key.
