Nematodes have been used as model organisms for evolutionary studies. This article highlights the key findings from research on developmental processes, sex determination, dauer formation, vulva development, male tail formation and developmental regulation of gene expression with regards to evolution. An updated phylogenetic tree of the phylum Nematoda is also provided. This article is an excellent read to summarise evolutionary differences within nematodes for the above mentioned processes.
