Neontology is a part of biology. In contrast to paleontology, it deals with living (or, more generally, recent) organisms. It is the study of extant taxa (singular: extant taxon): taxa (such as species, genera and families) with members still alive, as opposed to (all) being extinct. For example:
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 extant species, or if previously-known extant species are reclassified as members of the taxon.
The term neontologist is used largely by paleontologists referring to nonpaleontologists. Stephen Jay Gould said of neontology:
All professions maintain their parochialisms, and I trust that nonpaleontological readers will forgive our major manifestation. We are paleontologists, so we need a name to contrast ourselves with all you folks who study modern organisms in human or ecological time. You therefore become neontologists. We do recognize the unbalanced and parochial nature of this dichotomous division–much like my grandmother's parsing of Homo sapiens into the two categories of 'Jews' and 'non-Jews'.
Extant is a term commonly in use in biology to refer to taxa (singular, taxon), such as species, genera and families, that are still in existence, meaning still alive as opposed to extinct. For example, the moose is an extant species, while the dodo is an extinct species. Likewise, in the group of molluscs known as the cephalopods, as of 1987 there were approximately 600 extant species and 7,500 extinct species. This video is targeted to blind users.

hi i was motivated to make a clip about me and my cousin Sebastian "Devald", cause he is a good friend and he deserved it. its dedicated to Devald! cmt, rate and sub ReZenT~
cause i like this song i make this clip btw my 3k dgl frag... its free but pm me (btw botfrag)
Some of the basic terminology for dealing with phylogenies... including why "basal" is a bad word for an extant taxon.
