"Macro" vs "Micro" genetic "kind" mechanism?

Mosquitoes have mutated, cause of all the DDT spraying, and other sprayings, but how are they not still the mosquitoe. With all the mutatagens you'd think they would of macro-evolved, not micro-evolved. We're talking about a lot of generations, like a lot of mutations, but they are still being expressed as the mosquitoe. I mean if one wants to know the scientific name of any creature, go to the library, and you can look at the characteristics, and know the creatures scientific name, you'd think if macro-evolution was actually a happenings, you would see creatures macro-evolving, instead of micro-evolving. I suppose God got it all right the first time around, and via the male female gene swapping of the gene pool its kind of self correcting, is some way, like how in pure bred dogs, after the tenth generation the damaged gene is believed to of be purged from the gene pool. It does appear once the gene pool is established it protects the subspecies, that micro-evolved from the biblical kind, kind of like the ring species, that micro-evolved into a defined sub species of the species. The bible talks of the clean and unclean creatures, meaning this was written over 2,ooo + years ago, in spite of all these generations experiencing mutations, we are interestingly only see these biblical kinds of creatures reproducing, they apparently have not macro-evolved into new kinds of creatures, just sub species within their species (kind), if one wants evidence supporting creation, just go to the library, to find books to identify, all of Gods Creatures, cause they are only reproducing like kind creatures.
