According to My Son The Astronomer, evidence that we've already merged with other galaxies is that in Milky Way, there are groups of stars travelling in a different direction from the stars around them.

And eventually, all of the galaxies in our local cluster will merge into one truly enormous galaxy. By that time, all other galaxies will be so far away that no light from them will be able to reach us, and astronomers in that far-off future will have no way of figuring out how old the Universe is, or how it formed, or any of those basic things we currently have a good understanding of.
