I'll bet everything I got on 'hearing'. It was useful even before speech.

Which first evolved and which organism ?

Smell would be my vote. I can picture a cavemen after a heavy meal of woolly mammoth and swamp greens passing a particular pungent cloud of gas. I can picture another caveman close by jumping up with a disgusted look on his face and yelling, "WTH is that smell and who did it?" thus prompting speech. Concurrently hearing would follow to provide an early warning of other potential eye-waterers.

Human speech couldn't arise until the hyoid bone appeared a few hundred thousand years ago. Neanderthals may have been the first humans to speak.

Yep, that'd do it. A clan of 10-15 people, all on high protein diets in one small cave. oof!

I think speaking would be far, far more useful if people would also make use of hearing..

I have almost no sense of smell... severe hyposmia. It may be the death of me. I can only tell by sight if food has gone bad.

Man that has to suck. Smell is how we taste a lot of stuff too. Damn.

It does. And it comes and goes. I can taste things, so it's not complete anosmia. I can remember smells, so I must have lost the sense at some time in the past, but I don't know when.

No evidence for which was the first organism to evolve with the ability to produce sound as means of communication.

Was that really your entire purpose of this thread? To ask a question and reply to the first person who answers it with"Nope! There's no evidence for that!"???

 

[Mycroft]

Actually they evolved at around the same time/speed as each other. Beginning with little cilia that detect vibrations and, correspondingly, organs that transmit those vibrations.

It's an interesting question, because it really comes down to a more exact definition to what hearing is.

Good point -as we can talk to ourselves/hear ourselves without speaking via the aural loop (bypassing the need to speak and hear ourselves), figuring out how that works would be a good place to start.

They think that hearing started with the lungfish but i can't see a clear line of how speech evolved as many animals got it at the same time which is impossible, for example the ants can speak,so how all types got the beneficial mutation for gaining such capabilities at the same time.

Well where did you get the idea that many animals 'got' hearing at the same time? Sounds like you just don't quite understand what 'evolution'means.

Ants communicate by chemicals and recently they found out by noise as well.

A century-old mystery about how ancient freshwater fishes breathe has finally been put to rest, thanks to a study published last week in Nature Communications by a team of ichthyologists and me.

The fishes in question—Polypterus and related species—have tiny holes in the top of their heads called spiracles, and we showed how a small valve opens a bony lid over these spiracles to allow air to be sucked in and pumped out each time the fish surfaces.

And strangely enough, those same holes allowing the fish to breathe were modified through evolution to become eustachian tubes, which enable us humans to hear—but more about that later."


Evolution of hearing: Air-breathing fish adaptations turned into eustachian tubes.

Just to know as well, this animal was NOT a dinosaur and was called a Dimetrodon and they lived before the dinosaurs in the Early Permian Epoch, around 295–272 million years ago. They were the top predators at the time, like some of the top predators like T-Rex at the time of the dinosaurs. They went extinct in the permian mass extinction that killed over 95% of all life on Earth at the time. All life since then evolved from that 4-5%. However, evolution of their jawbones is why we have the jaw bones we have today and the way their jaws evolved and worked helped later animals increase in brain size. The jaw bones and muscles before them kept animals from growing bigger brains. .

The construction of the inner ear and vestibular system of Dimetrodon were described by Case, but he drew no conclusions about the possible function of these organs.

Which first evolved and which organism ?

Hearing first, because it's gives an organism a great advantage in terms of survival, both catching prey and avoiding predators. I'm not sure when humans first started speaking but in evolutionary terms it was a very recent development.
