In a later study comparing almost 3400 active genes in 70 spider species, Bond's team found that mostly webless, ground - dwelling arachnids such as wolf spiders and jumping spiders diversified much more quickly than web weavers, perhaps because they were able to exploit a plethora of new opportunities once they no longer had to build and tend webs.

Using bioinformatics tools to identify and map out specific components and regulatory interconnections, the study team found highly dynamic activities during CD8 + T cell responses: a distinct repertoire of super enhancers — groups of enhancers that interact with promoters to drive gene transcription, new groups of enhancers that jump into activity only in the memory cell stage, and extensive re-wiring of regulatory circuits from one cell stage to another.
