Having a full suite of reference genomes allows for all kinds of cool analyses.
Look at how much synteny there is among the sea turtles (first 6 shown, I don't know where Kemp's ran off to). That's despite the fact that leatherbacks (in blue) diverged from the other species >50 million years ago!

Global Decline in the Size of Sea Turtles
Changes in mean adult body size may be a universal response to global warming and sometimes lead to conservation concerns. Using a 30-year data set for green turtles from Malaysia, we show a decrease...
