Contrary to this conventional view, nearly half of the spiral galaxies of today, like our Milky Way, had peculiar shapes just 6 billion years ago — more recently than had been thought, the study found.

If confirmed, the finding highlights the importance to many galaxies of collisions and mergers in the recent past. It also provides clues for the unique status of our own galaxy,
