Recently, archaeologists have discovered evidence of a lost landmass called Sahul from ancient times, facilitating human migration across continents.
About Sahul:
- Sahul was a supercontinent that emerged during the last ice age, connecting present-day Australia to Papua New Guinea in the north and Tasmania in the south.
- It played a crucial role in enabling ancient humans to traverse from Asia to Australia approximately 7,000 years ago.
Ice Age Period:
- An ice age is a geological epoch characterized by extensive ice sheets covering large land areas, significantly altering the Earth's surface.
- The earliest known ice age occurred over 570 million years ago during the Precambrian era.
- The most recent widespread glaciations happened in the Pleistocene Epoch, ranging from 2.6 million to 11,700 years ago.
- Ice ages do not maintain a consistent level of coldness; they experience fluctuations with colder periods leading to extensive ice coverage and warmer periods resulting in reduced ice areas.

Kanwar Lake, previously a haven for migratory birds, is now facing challenges to its existence.
About Kanwar Lake:
- Asia's largest freshwater oxbow lake, also known as Kabartal jheel, is a rainfed lake.
