Practice question

Neo-systematics or new systematics term coined by Sir Julian Huxley in 1940 in influential book The New Systematics advocating inclusion of cytological, genetical, ecological, anatomical and biochemical data for delimitation of taxa rather than relying solely on herbarium morphological characters. Darwin proposed natural selection mechanism 1859, Linnaeus binomial system 1753, Haeckel phylogenetic terminology and recapitulation. Huxley's proposal marked clear transition from classical alpha taxonomy to integrative biosystematics influencing Ernst Mayr biological species concept and modern polyphasic approaches. Recognition of Huxley as father of new systematics underscores historical paradigm shift towards evolutionary synthesis in classification theory and practice.
