An enthralling book on monkeys and apes of the rainforests. Fascinating facts about several primate species are reflected and appealingly narrated from experiential encounters in the wilderness of Borneo. The author brilliantly takes readers through the evolution of man by selectively highlighting the physical features and behavioural biology of the species discussed in the book. Unprecedented destructions of the rainforests have driven countless animal and plant species to the brink of extinction, including monkeys and apes. Immediate and effective conservation of the rainforest habitats remain their last hope. In this book, the author is advocating mindful approaches to saving these endangered species from disappearing forever. Evolutionarily, we need to recognise the unique commonality between us humans and the primates. The connectedness goes beyond the evolution of morphological changes and adaptable features. We also share the genesis of learning behaviour and building of culture. Additionally, the book is delightfully illustrated with drawings by the author himself as he reveals the science of nature through the eyes of a naturalist.
