Ring species of seagulls, are seagulls on both ends, same with your beetles, lizards, moths, bacteria, all the different kind of apes, .. and the 7 billion humans covering every corner of the world, are still the same species.
Ring species are an interesting example of how speciation involves
populations that, over many generations, have become different enough to be considered separate species. What you mean by "beetles, lizards, moths, bacteria..." being "still the same species" isn't clear - as you quoted in your post there are hundreds of thousands of beetle species alone, so they're clearly not "still the same species".
... why not get some camera on them, an entire population of them, and see when it speciate into another distinct species!? If it wakes up the next day as a seagull, or lays a seagull egg, you have no proof for this 'Evolution Theory'.
Because it doesn't happen that way; the population gradually changes over many generations; there is no overnight change. The process is analogous to the changing stages of human life; there's no overnight change between baby and child, child and youth, youth and adult, etc., life is a continuous process of change; so different cultures and societies make a decision on when they will consider a transition to have occurred according to some selected criteria, e.g. appearance of body hair, or voice change, or age in years, or arrival of periods, etc.
Declaring that speciation has occurred is a similar process - it means we've decided to distinguish two populations as distinctively different based on selected criteria, e.g. reproductive capability, or genetic differences, or stable phenotypic differences, etc.
We both agree that no distinct species of one kind has, or will ever evolve into another completely distinct/different species (like a duck into a crocodile, a gorilla into a human, a seagull into dolphin or whatever), not in the lifetime of the species.
No species will ever evolve into another existing or past species - they will always evolve into
new species; and those new species will eventually evolve in turn (unless they go extinct) into one or more new species, and so-on. The species they evolve into will become ever more distinct/different from the original parent species until, many species down the line, they may appear to be
completely different from the original parent species. Ring species show a speciation stage of this process in detail, where the intermediate populations between one species and the next still exist.
The tree of all life on Earth is the result of this process of branching speciation, where so many changes have occurred between early species and contemporary species that the contemporary species look
very different from the original ancestor species, and the many ends of the branches (lineages) look different from each other according to how far up the tree their branches separated.
What you do tell me is that this does happen in the grave, and the proof is all the millions of 'transitional fossils, and skull & bones' they have on display as 'evidence', enhanced by Peleoartist's paintings to look like the desired "common ancestors" you are looking for, these paintings all lined up in sequences to give the illusion of speciation, .. like a gorilla morphing into a human.
Fossils are the evidence of past speciation of populations that lived in those times.
So why continue defending something that even you Evolutionists admit to never happens, that Evolution/speciation of one distinct species into another distinct species NEVER happens in real life, or while the species are alive!? We are on agreement with that, so why push your religious belief of something we both agree never happens?
You've misunderstood - a species can give rise to a new species and still continue to exist. If part of a population of a species is isolated in a new environment, it will progressively adapt to that environment over many generations, eventually becoming a new species. Meanwhile, the other population(s) of the species, if well-adapted to the original environment, may remain relatively unchanged; so you will have a new species that has branched off from the original species, where both species exist at the same time. This has often occurred when breeding pairs become isolated on islands, for example. Of course, given enough time, the original species (if it doesn't go extinct) will change sufficiently to be considered a new species too.
