What is the youngest rainforest?

The youngest rainforest is the Amazon Rainforest, which is believed to have formed around 55 million years ago after the last major ice age. While it is often referred to as ancient due to its vast biodiversity and complex ecosystems, geological studies indicate that it is relatively younger compared to other tropical forests. The Amazon continues to evolve, influenced by climate changes and human activity, making it a dynamic and critical environment for global biodiversity.
