Awesome! Did the complex pharyngeal slits really mutate into complex gill slits?
Um, no. Did anyone ever say they did? I think you'll find that as soon as pharyngeal slits appeared in proto-chordates they were gill slits. Over time some vertebrate phyla developed which no longer required the gill slits for respiration although they are still sometimes inaccurately referred to as gill slits or branchial slits, even though they aren't associated with gills anymore and are not necessarily ever true slits, many structures which develop from the surrounding pharyngeal arches were retained and modified.
Sounds like a couple thousand repressed deleterious mutations expressing themselves together advantageously. Cool! Now what are the odds, really?
The odds are probably higher than of you ever making a post which accurately represents any aspect of evolutionary biology. You still seem to have no idea what evolutionary theory posits, no wonder you think it is a fairy tale, the version of it you are familiar with
is but it was one made up by creationists.

P.S. How complex is a slit? Seriously. Some of the accessory structures may be complex but a slit itself is probably about as uncomplex a structure as you can come across.
