In my earlier post where I said "lobe finned fish, amphibians, reptiles, and mammals have a nasal passage to the throat" I should also have said that birds also contain a nasal passage to the throat.
Please see https://www.pbs.org/wgbh/evolution/library/03/4/l_034_03.html . It says the following.
'Paleontologist Jenny Clack thought the textbook story of tetrapod
evolution was implausible: How could fishlike creatures, stranded on
land, somehow evolve limbs and survive to become the first tetrapods?
The search for an answer took her to Greenland, where she found one of
the earliest known tetrapods, called Acanthostega. With its
fishlike tail and gills, it was certainly adapted to an aquatic
environment, but its paddle-shaped fins end in tiny fingers. Vertebrates, it turns out, grew fingers before they left the sea. From Evolution: "Great Transformations"
'
Please note that the last paragraph of the above mentioned PBS web page says the following about Acanthostega and Ichthyostega.
"From these finds, it now appears that the four legs common to land
animals today really evolved for another purpose: navigating swampy
wetlands, not as a means of moving to land. But once on land, the
animals found their limbs a survival advantage there, too. Evolution
frequently produces adaptations that come to be useful in the future for a different purpose."
I wish to quote a lot more from the above mentioned web page, but if I
did so it would amount to quoting nearly the entire page, thus I urge
people to visit the web page.
Please also read the science news article located at https://www.livescience.com/42525-early-fish-evolved-rear-legs.html . It is called "Strange Ancient Fish Had Front And Back Legs". It is about a fossil of a "375-million-year-old fish known as Tiktaalik roseae, discovered in 2004". It says the following regarding the fossil.
"These findings reveal that a key step in the evolution of hind limbs happened in fish, challenging previous theories that such appendages evolved only after the move to land.
...
This ancient creature was undoubtedly a fish, possessing gills, scales
and fins. However, it also had features seen in modern tetrapods —
four-limbed creatures like amphibians, reptiles, birds and mammals —
such as a mobile neck and robust ribcage.
This extinct fish had large forefins and shoulders, elbows and partial
wrists, enabling it to support itself on ground. This makes it the
best-known example of an intermediate between finned animals and limbed
animals marking the evolutionary leap from water to land for
vertebrates, or creatures with backbones."
