Which evolved first,hearing or speaking

Yes tiny changes for hundreds of thousands of years.

For example one generation were able to say a..a...a, and that was beneficial for the generation and the ones saying a...a.....a passed
the gene to the next generation and the one who failed gone extinct, then the next generation were able to say ma.....ma...ma and that was beneficial
for survival, yes very very tiny changes, make a lot of sense to be naturally selected.

"Yes tiny changes for hundreds of thousands of years."

Millions of years

To pronounce sounds as for humans then physical changes was a must and such changes were very tiny that it took hundreds of thousands of years from monkey like to what human is, so for natural selection human didn't speak in one day night, but physical changes for very long period of time, so yes the sound changed slowly,a...a.....a. then with time physical changes improving pronunciation ma....ma.....ma, then we can say now BS.

Natural selection is wonderful and very easy to understand.

Primate Behavior
Humans are part of the biological group known as primates. We sure are an unusualspecies of primate, though!

Primates include lemurs, lorises, tarsiers, monkeys, and apes – a group of species that is well known for being social, smart, and very adept at using their hands. They are also very vocal and communicative with the members of their social group. And they move around in a wide variety of ways, including sometimes on two legs.

Remind you of anyone?

We invite you to enjoy the most unusual primate of all!



Some non-human primates can communicate using symbols. So how are humans different? Watch this video to find out.

When Did Humans Start Talking?
Scientists are not sure. Spoken language does not fossilize, and there are few clues about when our ancestors began to use complex language to communicate.

However, making and using some of the objects here, which date back 350,000 years, involved complex behaviors that probably required language.

Spoken language became possible when the voice box dropped lower in the throat. Image courtesy of Karen Carr Studio.

Benefits and Costs of Talking


Benefits

Spoken language is essential to modern human cultures. We use language to communicate in a complex, ever changing world.

As our bodies evolved for speech, the voice box dropped lower in the throat. The area above the vocal chords lengthened, enabling us to make a wide variety of sounds.



Costs

When the voice box dropped to make speech possible, it became impossible to swallow and breathe at the same time. Food could get stuck in the larynx and cause choking.

Because human babies do not have a lowered voice box, they can breathe while nursing like other mammal infants.

So we got the ability to speak by coincidence , because evolution is directed by natural selection otherwise it's the work of chances and coincidence and hence you imply that our ability to produce verbal sounds that make frequencies in air was by chance.

This idea is not a new one. The poet Lucretius posited it in his work De Rerum Natura over 2000 years ago. It's very likely that his theory was based on that of Epicurus from a few centuries earlier.

But terms like "chance" and "coincidence" are misleading. The entire point of the theory of evolution by natural selection is that evolution is not random. Genetic mutation is, but natural selection is the process that brings order to it and results in specific, complex outcomes. If you're still thinking that the evolution of sensory organs and so forth is supposed to have happened entirely by chance, then you have not made a good-faith effort to understand evolutionary science.

And if you are not here to learn in good faith, what exactly are you here for?

Hearing is an advantage for survival and hence it was naturally selected, but what if speaking( was evolved first, will it be selected regardless of hearing or it won't be selected.

What do you think ?

It could be possible for interspecies communication, but not intraspecies communication.

For example, a rattlesnake Rattlesnake - Wikipedia, the free encyclopedia does have hearing. But I believe it would be quite possible for the warning rattle mechanism to evolve even if it did not.

The sound communication of the snake is intended to warn an individual that can hear. So the sense of hearing does predicate communication by sound. But I can conceive that evolution could select the ability to communicate through sound, even though the communication species itself could not hear.

A real example might actually exist if we shift to color communication and eyesight.

Flowers evolve color communication, even though they can't see. These colors attract pollinators including insects, mammals, birds, etc.

Insects such as butterflies have evolved striking color patterns to warn birds that they are toxic. But the insects themselves do not always see the same wavelengths as the birds. A monarch is such a species. Another species, the queen butterly has evolved to look almost identical (to the bird's eyes) as the monarch. Even though the queen is not toxic, the bird can't tell the difference. So how does the male queen know the female queen from the female monarch?

To the butterflies and other insects, the two look very very different.

Here is another example.

UV color a hidden signal for butterflies This is an elegant example of the complex simplicity of evolution.

Creatures weren't in need for speech and lived for so long by hearing, so speech isn't a factor for survival, why it passed to the next generations, will the creatures die for not speaking, reaching the top of the tree.

There are no examples of any trait ever evolving because of a need. Traits evolve because they are already there, in the form of a mutation, and they happen to provide an advantage. Not fulfill a need.

I don't understanding evolution, is it that hard !?

Do you agree that the organism needs thousands of years to evolve and change kind?

No. This is a misunderstanding. Organisms simply are incapable of evolving. Evolution affects the population gene pool.

IOW if one kind isn't speaking then the evolved one needs thousands of years to change kind and speak.

The premise is a misunderstanding, and therefore this conclusion is misleading your understanding.

If you agree then you should answer the question.

How natural selection is directed while change of kind needs hundreds of thousands of years to take effect and to be beneficial.

If what i said is correct then answer the question and if there is something wrong in what i said then please clarify where is the mistake.

What you say is in no way correct.
