It allows you to research advanced ancient techs. IE: you've found ancient ruin with Massive Ionic Disperser, and it gives you the comp itself and tech area with the same name (only 1 level). But if you have Xenoarcheology 1 you'll also get additional tech - Massive Engine Destroying Weapons with 5 levels to research and more comps.
Some high grade unique techs (like Adamantium armor) require higher levels of Xenoarcheology.
