Final answer:
Ancient civilizations with intensive agriculture did not develop in Australia. Areas like Mesoamerica, Western South America, and North China were home to early agricultural societies, particularly those focused on maize.
Step-by-step explanation:
Ancient civilizations based on intensive agriculture developed in many regions around the world, but not in Australia during the times in question. Intensive agriculture led to the rise of civilizations in regions like Mesoamerica, Western South America, and North China. For instance, maize agriculture began in Mesoamerica around 8,000 years ago and then spread to other regions such as central Mexico about 6,000 years ago. These early agricultural developments occurred along fertile river valleys, which provided the necessary conditions for sedentary agricultural societies to develop.
