This paper examines the ancient Indian cosmological doctrine of 84 Lakh Yoni — the classification of 8.4 million species of living beings — through the lens of comparative biology, philosophy of science, and Indigenous Knowledge Systems (IKS). The doctrine, rooted in Vedic and Jain cosmological traditions, posits a structured taxonomy of six primary biological kingdoms: plants (2,000,000 species), aquatic creatures (900,000), amphibians (100,000), terrestrial animals (3,000,000), aerial creatures (1,000,000), insects (1,000,000), and humans (400,000). This paper further integrates the temporal cosmological framework of Manvantaras — nested cosmic time cycles derived from celestial mechanics — within which these categories of beings are said to sequentially manifest, constituting a non-Darwinian account of biological emergence. The doctrine situates the diversification of life not within a linear historical progression, but within a hierarchical, cyclical model of time governed by the motions of celestial bodies — spanning units from Yuga (12,000 years) to Chaturyuga (48,000 years), Manvantara (288,000 years), and Kalpa (1,152,000 years). The paper critically compares this framework against modern evolutionary biology, challenging the reductionist assumption that one species transforms into another through gradual morphological change, and instead engaging the IKS premise that speciation occurs through independent ontological emergence at cosmologically determined stages. The doctrine's account of human biodiversity — proposing 400,000 morphological subtypes — is examined in relation to modern genomics. Karmic and soteriological dimensions of this framework are also explored for their bioethical significance. This work contributes to the growing scholarly dialogue between traditional cosmological knowledge and modern life sciences.
