Comparatively, little is known about the genome size in Theraposids, and what meaning it has, although this gross type of analysis has been conducted in the brazilia white knee, Acanthoscurria Geniculata and Stegodyphus mimosarum (a social member of Eresidae, velvet spiders) on one side, and 'true' spiders (see my other thread),perhaps with evolution of silk or venom in mind.
In many respectes the genome size and number of gene repeats were larger in the theraposid Acanthoscurria. I speculate about this with the differences in that Tarantulas in general have a longer life span but are less active and need to gear up with larger genetic tools to adapt? This reminds me about the tomatoes, 31,760 genes which means 7,000 more genes than humans. But of course plants in general have vast genomes because they cannot move... What are your thoughts on this?
