Neotologist

Briefly stated, the transformational view of the origin of species (a view most commonly found in the paleontological literature but not uncommonly broached when neotologists think about how species "behave" in geologic time) sees evolution as the accumulation of morphologic, hence genetic, change

Paleontologists and neotologists alike have placed emphasis on the role of developmental constraints on evolution (Albrech 1982, Gould 1980, Iltis 1983).

While neotologists have concentrated on unraveling how the three living groups and the trilobites are related to each other, paleobiologists have used the additional data from these unaligned fossils to derive a more inclusive classification.

We sent in a neotologist and in 2 years he brought that rate down to less than half of what it was before.
