| Abstract | The living fossil concept continues to foster development of integrative research, as it has done since Darwin’s use of the term in 1859. It has been applied to a vast menagerie of biological entities across the kingdoms of life and at many levels in the biological hierarchy. Correspondingly, a number of primary living fossil criteria emerged and persisted all the while as disciplines, theories and practices of biology transformed. In this paper we attempt the first comprehensive analysis of the use of the term ‘living fossil’ from 1860 to the present. Employing a compilation of 719 publications and 853 unique entities, we examine: (1) patterns of change in the phylogenetic diversity of living fossils, their taxonomic ranks and groups, (2) the diverse subject areas in which living fossils play a role, and (3) the primary criteria used to designate living fossil status. Our analyses reveal how the menagerie has extended and diversified alongside technological developments in biological research. The average number of living fossil criteria applied per entity has escalated even more rapidly than the menagerie has expanded. We argue that the demonstrated persistence, ever-expanding scientific and public interest, and future utilization of living fossils reflects increasingly complex challenges to deep-seated expectations at the heart of a living fossil research agenda: omnipresent evolutionary change and inevitable disappearance or extinction. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
