Neontology
Neontology is a part of
- The moose (Alces alces) is an extant species, and the Irish elk (Megaloceros giganteus) is an extinct species.
- In the group of molluscs known as the cephalopods, as of 1987[update] there were approximately 600 extant species and 7,500 extinct species.[1]
A taxon can be classified as extinct if it is broadly agreed or certified that no members of the group are still alive. Conversely, an extinct taxon can be reclassified as extant if there are new discoveries of living species ("

organisms in human or ecological time. You therefore become neontologists. We do recognize the unbalanced and parochial nature of this dichotomous division.[2]
Neontological evolutionary biology has a temporal perspective between 100 and 1000 years. Neontology's fundamental basis relies on models of natural selection as well as speciation. Neontology's methods, when compared to evolutionary paleontology, have a greater emphasis on experiments. There are more frequent discontinuities present in paleontology than in neontology, because paleontology involves extinct taxa. Neontology has organisms actually present and available to sample and perform research on.[1] Neontology's research method uses cladistics to examine morphologies and genetics. Neontology data has more emphasis on genetic data and the population structure than paleontology does.[2]

Extant taxa versus extinct taxa
Neontology studies extant (living) taxa and recently extinct taxa, but declaring a taxon to be definitively extinct is difficult. Taxa that have previously been declared extinct may reappear over time. Species that were once considered extinct and then reappear unscathed are characterized by the term "the Lazarus effect", or are also called a
Neontology importance
Neontology's fundamental theories rely on biological models of natural selection and speciation that connect genes, the unit of heredity with the mechanism of evolution by natural selection.[10] For example, researchers utilized neontological and paleontological datasets to study nonhuman primate dentition compared with human dentition. In order to understand the underlying genetic mechanisms that influence this variation between nonhuman primates and humans, neontological methods are applied to the research method. By incorporating neontology with different biological research methods, it can become clear how genetic mechanisms underlie major events in processes such as primate evolution.[11]
