The aims of this display is to draw a clear understanding of the evolutionary trends of the animals Linnaeus, loosely termed Vermiforms, or "worm like creatures".

The western tradition of classification officially began with Carlos Linnaeus, who in 1758, set the standard for zoological nomenclature, now known as the Binomial system. In it Linnaeus recognised two classes of invertebrates; Insecta which included - crustaceans insects, arachnids, centipede, and millipedes, all distinguished by the possession of antennae; and Vermes, distinguished by the presence of "tentacula". The remaining classes were for vertebrates.

The Linnaeus classification is the arrangement into groups of living organisms on the basis of observed similarities and differences.

During the eighteenth and early nineteenth century as our understanding of the taxonomy of invertebrates significantly increased, scientists realised the inadequacy of the Binomial system.

A new classification, Phylogeny, was developed which explained degrees of evolutionary relatedness in classification.

The Phylogenetic practice is that of separating true homologies (features of the same evolutionary origin) from characteristics resulting from evolutionary parallelism or convergence.
