Which evolved first, the Eustachian tube or the eardrum.

[FearGod]

For those who believe in luck and that things may work well without prior plans,
how the ear evolved to perceive the sound waves, was the Eustachian tube first
evolved and then the eardrum next, or was the eardrum first evolved and next
the Eustachian tube, or both happened to evolve together simultaneously during the
process of evolution in the period of millions of years?

That's a bit above my paygrade.

Eustation tubes are remnants of internal gill structure and existed in vertebrates prior to eardrums.

I don't know why you can't use google ... the answers are all there: Jaws to ears in the ancestors of mammals

Your fixation with place order is misplaced, there is no taking of big evolutionary leaps, but rather small, basically simultaneous baby steps. Your argument is based solely on the semantics of when do you apply a new name to a structure that is changing on a continuum ... it is philosophically dishonest.

No it isn't - this is not a legitimate question at all.

This is just the latest spam-trolling thread that this guy has started asking similar dopey "questions."

Hmm. Give us reason a reason this is significant
before I dig through boxes for my copy of
Romer.

As a general concept, e@aly stages of either
would be dissimilar to their modern countrrpart,
kinda like your jaw is not much like a gill arch.

Anyhow- why do you ask?

For those that believe a tribal deity fashioned a man from dust, please explain which was created first -
the Eustachian tube or the eardrum!

You is talkin about malleus stapes etc, not eardrum.

Ah, whoever it is has went to ig city, so I missed noting that it was
another of a series of spam trollongs.. May I suggest we cease to rise to the bait.

But then we will never know which evolved first!

اDoes it mean that there was a tube but no eardrum during the process of evolution,
which creature after fish that has the Eustachian tube without eardrum?

What was the first design decision of the Master Designer when He designed our sexual organs?

1] to output waste like urin and such
2) to generate immortal souls

I believe that those who believe that the amazing structure of the ear and how
it works was just the work of natural events are so crazy indeed, as I said before you're
fooling your own selves and you're believing your own lies, you can prove me wrong
if you have evidences, you have only assumptions, such as it happened that the
Eustachian tube was formed as a remnant from the fish's gill and it happened
that the eardrum evolved and it happened to be useful for the species and hence
passed to the next generations,eh

I'll keep posting such kind of questions which seem to annoyed you?

What's your evidence that it was formed from the fish's gill?

Salamanders and some basal reptiles have no ear drums but still have middle ears and eustachian tubes.

All salamanders lack middle ear cavity, eardrum and eustachian tube.

Do I have to agree with anything in google? why to debate then?

You keep posting "gotcha questions" that only tell us that you have no clue as to what you are debating against. You cannot refute that which you do not understand. And in answer to your question many structures are repurposed through the process of evolution so it does not really matter which one was first. Neither part originally had anything to do with hearing.
