What is the difference b/w Ultra Conserved Elements (UCE) and orthologs

HI,

Can someone give a good definition of the difference ?

Thanks

UCEs are short- and medium-sized stretches of DNA that are identical between different species. They are often non-coding.

Orthology refers always to coding sequences. It requires that function be conserved between different species, but there is no requirement for identical sequence.

While presumably there is a requirement for functional conservation in both cases, evolutionary pressure for sequence conservation is larger on UCEs than orthologs.

Well, Is their any tools (?) able to predict UCE's from genome data, with out knowing bait information.
