Pseudoextinction

Pseudoextinction, also called phyletic extinction, can sometimes apply to wider Taxon s than the Species level. For instance, the entire Superorder Dinosauria is believed to have become pseudoextinct by many Paleontologist s, who argue that the Feathered Dinosaurs are the ancestors of modern day Bird s. Pseudoextinction for taxa higher than the genus level is easier to prove.

Some Neoeugenicists , such as Gregory Stock argue that Genetically Engineered “ Designer Babies ” will ultimately lead to Human pseudoextinction.

The Last Human - Excerpt from ''Redesigning HUMANS'' by Gregory Stock, envisaging the engineered evolution of modern humans into a Posthuman form, and saying: "Such an occurrence would more aptly be termed a pseudoextinction, since it would not end our lineage. Unlike the saber-toothed tiger and other large mammals that left no descendants when our ancestors drove them to extinction, Homo sapiens would spawn its own successors by fast-forwarding its evolution."
