Species and Speciation Concepts

The video is part of the PYQ series focusing on species-related questions in geography and environment. It discusses the lion-tailed macaque, its habitat, threats, and IUCN status. The video explains the use of flashcards for memorizing species details and covers concepts like keystone and umbrella species, allopatric and sympatric speciation, and sentinel species as environmental indicators. The video concludes with a call to action for viewers to engage with the content.
