385 million years ago, a group of fish would undertake one of the most important journeys in the history of life and become the first vertebrates to live on dry ground. But first, they had to acquire the ability to breathe air.

Pretty cool to thin that the legs we walk on today originally came from modified fins that lobe finned fish used to walk through shallow water that was probably rife with plants and other debris. And the lungs that we breathe through originally came from modified swim bladders whose function shifted from regulating buoyancy to taking in oxygen directly from the air. Evolutionary biology is immensely fascinating.

I think of it not as breathing air, just needing less water. The insides of your lungs are quite wet as they need to be for gas exchange to occur. Gases (such as oxygen) dissolve into the moisture of your lungs, continuing to transfer into the water in your blood, CO2 goes the opposite way. We air breathers keep a bit of water with us, coating the inside of our breathing organs.

Also, the ability to breathe air gave an evolutionary advantage: being able to escape predators. In time, the ability to remain longer periods of time in land, became the standard, as fewer species returned to land, since there was more availability of food in land, filling the required niches in nature.

I have been watching a lot of Eons-videos lately, and this is now my favorite channel on KZfaq. As always I hope you make more videos about dinosaurs. Especially if you could talk about some of the latest discoveries that have been made: new species, feathers/colors and so on. Or, you know, just a documentary about the Diplodocus or something :D

There is much evidence that the vertebrate lung originated from a progenitor structure which was present in bony fsh. However, critical basic elements for the evolution of breathing in tetrapods, such as the central rhythm generator sensitive to CO2/pH and the pulmonary surfactant, were present in the lungless primitive vertebrate. This suggests that the evolution of air breathing in all vertebrates may have evolved through exaptations. It appears that the capability for proliferation of alveolar type 1 (AT1) cells is the “critical factor” which rendered possible the most radical subsequent innovation-the possibility of air breathing. “Epithelial remodeling,” which consists in proliferation of alveolar cells-the structural basis for gas diffusion-observed in the alimentary tract of the gut-breathing fshes (GBF) has great potential for application in biomedical research. Such a process probably led to the gradual evolutionary development of lungs in terrestrial vertebrates. Research on the cellular and molecular mechanisms controlling proliferation of squamous epithelial cells in the GBF should contribute to explaining the regeneration-associated phenomena that occur in mammal lungs, and especially to the understanding of signal pathways which govern the process.

@ThomasHoltzGEOL 5 жыл бұрын

Great video, as always. But you have the evolutionary order (character state polarity) of the lung and swim bladder backwards. Lungs are ancestral, and are widespread in primitive bony fish (like bichirs, bowfins, and dipnoans [so-called "lungfish"]). Tetrapodomorphs inherited the ancestral trait (itself evolved from an outpouching of the gut). The swim bladder is a modified lung, found in the vast majority of bony fish.

You should do an episode about Miguasha! It's one of the best fossil bed in the world, maybe the most diverse from the Devonian, and is now a national park open to the public in summer, with a comprehensive museum adjacent to it. I went there and it was incredibly fun. I'm sure they would let you film an episode if you ask.
