Several aspects of Parhyale embryological development are derived when compared to other peracaridian species such as isopods and mysids (cell lineage and early cell-cleavage patterns, as well as later gene expression correlating with the development of specific morphological structures). Examples of the types of characters we are actively exploring are variations in early embryonic cleavage patterns and associated cell lineages (Gerberding et al., 2002) and changes in the expression patterns of genes involved in embryonic segmentation, limb patterning, and nervous system patterning (Browne, 2003; Browne and Patel, 2000; Duman-Scheel and Patel, 1999; Averof and Patel, 1997). re T3 c o 60 c re U v re -O :- aj 60 o c o 0 u o W3 I/} \ V .3 Ka. o> re -c o u V <J '-u V O 01 01 a JS v â¢u ~ re â¢- -c -o .5 2 '2 C 41 <j re a. o <u c S Q 'â X -c re V) JO '5b i- re 'd re "5. o> re o> o o u 2 a. re U .2 'Jo .Si. âi re â a i* re O o 01 a.

The Kim and Kim, 1993 phylogenetic analysis of several morphological characters propose a monophyletic Hyalidae (indicated by red box). Parhyale hawaiensis is a member of this large family of amphipods. The Talitridae are considered sister taxa to the hyalids. The talitrids include Orchestia cavimana, an amphipod in which cell lineage and gene expression analyses have been reported ( Wolff et al., 2002; Scholtz et al., 1994). It is important to note that the affinities among most amphipod groups are far from resolved and this represents only a first approximation of relationships within th
