I would like to thank Robert or Glen, or whoever for posting this

This is a question I have had several times - e.g. I typically have a
good guess about a divergence time, (e.g. 15 million years rat to
mouse) but am not sure I am correct, and certainly cannot find a
reference to that to save my life.  I think that a database of good
primary literature references in evolutionary biology, especially on
divergence times, to help out us poor molecular biologists, would be
most appreciated!
