Analyze the effect of isolation on the Australasian ecozone

Geographic isolation prevents gene flow with other landmasses, leading to the evolution of unique, endemic species that are found nowhere else on Earth.

Evaluate the given options

• "Differences between eastern and western Australia" refers to internal regional variations rather than the effect of continental isolation.
• "Development of the platypus" is a prime example of an endemic species (a monotreme) that evolved uniquely due to Australia's long-term isolation from other continents.
• "Variety in Australia's climate" is driven by latitude, atmospheric circulation, and topography, not biological isolation.
• "Volcanism on the Australian coast" is a geological process related to tectonic plate boundaries, not biological isolation.
