Escarpment evolution in Madagascar unveils a pathway to understanding island biodiversity

A recent study on the flora diversity of the escarpment region in eastern Madagascar provided new insight into the mechanism of species diversification. Here we review this paper and emphasize the importance and novelty of the key findings and the methods. We suggest exploring the commonality of the findings in other regions with high biodiversity. We also recommend the examination of more relative case studies and wider application of the novel simulation method.
