For the sake of those interested I want to make a very small correction to your notion of evolution.
First thing, all living organisms have evolved to the same degree.. It’s characteristics are determined by the usefulness of the characteristic that living organism has.. If there is no rate limiting characteristic to an evolutionary change, it might get preserved over generations due to various interacting factors or it might get lost at some point, the rate limiting ones are the ones that matter in evolution mostly, because, for example, if an evolutionary change means that the organism with that trait lives longer and produces many offsprings, then that will eliminate most of the species which do not carry that genotype, hence it is rate limiting.. others which do not have such rate limiting effect will have no effect on continuation of species, and such will be just evolutionary byproducts, which might be very useful, like language in humans… but that is not a very good rate limiting factor..
And for your information, many animals do have some sort of communicating powers, we just don’t understand their language all the time, we do understand some very faintly, but not all,
And one more important thing is, speciation occurs because of accumulated genetic changes, and these genetic changes are dependent on environmental factors, exposure to radiation, genetic replication and such factors, and contrary to popular belief among theists, it is not just a random and chance occurrence.. and these genetic changes happen differently in different geographic, environmental conditions, that is why we see certain marsupials specific to certain areas and so on.. so based on these changes and evolution by natural selection, we get equally evolved species at any given point in time, but we erroneously favor certain particular characteristics that make us human as the yardsticks to measure evolution. That in my opinion is not correct. Just because we love some things about ourselves like overt reasoning and language does not make us superior to any other living organisms.
My best example would be compare yourselves to HIV, it is highly successful at replicating itself and continuing its progeny and it is ruthless at it, but it does not have any language or thought process, which does not matter to it at all.. not even remotely, it is highly evolved to sustain its replication cycle, there is no need for it acquire language.
I hope this is sufficient.
