The island had to be connected to the mainland in the past.

Explanation:

According to the research studies carried out by Quintana, Dr. Meike Kohler, and Dr. Salvador Moya-Sola, it was concluded amongst other things that the giant rabbit scientifically referred to as Nuralagus Rex, got to Minorca around the Messinian crisis 5.3 million years ago.

However, the movement was made possible due to the drying up of the Mediterranean sea, thereby making the Balearic islands connected with the nearby area. Thus, these giant rabbits were able to move to Minorca through land or walk.
