Komodo dragon collision between Australia and Southeast Asia allowed these larger varanids to move back into what is now the Indonesian archipelago, extending their range as far east as the island of Timor. The Komodo dragon was believed to have differentiated from its Australian ancestors 4 million years ago. However, recent fossil evidence from Queensland suggests the Komodo dragon actually evolved in Australia before spreading to Indonesia. Dramatic lowering of sea level during the last glacial period uncovered extensive stretches of continental shelf that the Komodo dragon colonised, becoming isolated in their present island range as sea levels rose afterwards.

Ibiza wall lizard Ibiza wall lizard The Ibiza wall lizard ("Podarcis pityusensis") is a species of lizard in the Lacertidae family. It is most closely associated with the island of Eivissa, or Ibiza, in the Balearic Islands, but has become naturalised in parts of Spain. A sub-species, "P. pityusensis formenterae", is limited in natural habitat to the islands of Formentera, Illa Cordillera and Es Vedrà, south of Ibiza, but has been transported by humans to several other locations in the Mediterranean. The Formentean subspecies tends to be more brightly coloured than its Ibizan and mainland conspecifics. The natural habitats of "P. pityusensis" are
