4.4: Interspecific vs. Intraspecific Variation

When you lump a bunch of fossils together and call them a paleospecies, you are saying that all the differences between the fossils are intraspecific variation, variations within a species. If you split all the different looking fossils into separate species then you are seeing interspecific variation, variation between species; intra- means "among" and inter- means "between"
