And some also don't have myoglobin, or at least not in all of their muscles, which is also crazy

[@ruslbicycle6006]

Two questions this doesn't answer: -Why does it swim with it's tail bent sideways? -Isn't it an obvious advantage to not require so much iron/hemoglobin? Iron is hard to get, for humans it may be what pushes us to eat meat, harder to catch than just eating plants. An maybe lack of iron allows lower metabolism? I'm just guessing, but it seems like the discussion in the video isn't addressing these obvious questions.

[@xEricC1001x]

I also wondered about the tail. As an aquarium keeper it's common knowledge that that exact look means the "fishkeeper" who took the photo in captivity had poor water quality with too high of nitrates over an extended portion of the fish's life and the chemical led to a deformation of the spine.

[@janjanzen1218]

Hi, thats what I suspect as well. Iron is very rare in the southern ocean, as iron usually comes from terrestrial sources and there are just less landmasses in the southern hemisphere. In the Atlantic a lot of Iron gets blown in with winds from the Sahara. I now that a lot of species of Phytoplankton in the Antartic have very intersting adaptations to low Iron concentrations. As Iron is an essential part of hemoglobin, it would surly save a lot of Iron not toproduce it

It sounds like the genetic mutation was better than "neutral", especially considering the changes that were made to their vasculature and overall blood volume to compensate. It was probably advantageous. Do they have blood cells? Im assuming they would not need them. Blood cells are a huge investment with such high turnover. Populations with clear blood obviously had a selective advantage over populations with functional hemoglobin, likely because the energy expense wasn't worth it.

[@quitlife9279]

I agree. I also think it is only logical to consider that if a particular trait exists, it must be advantageous compared to the previous trait that it replaced through natural selection, or else it would not exist according to the theory of evolution.

[@Kuichio]

Is it possible that humans losing the ability to create vitamin C, given that the environmental source was abundant, was not actually a neutral mutation? What if that process being limited freed up some energy use elsewhere? It is interesting to wonder if, after this mutation, did another arise that was only possible because of this mutation. Are some mutations known to be dependent on other, prior mutations? I suppose if you consider a macroscopic view of the tree of life, everything HAD to develop that way, though as always, those less meaningful mutations always cloud the view. But it is certainly amazing to think about these physical processes, and realize that these random mutations have steered us this way, yet there was always another avenue that life could have developed into, but it never will. I relate this forever lost knowledge to language and the tower of babel website. The site has every configuration of every word. You can even find this entire comment somewhere within the never ending paragraph, but there will be no context. Theoretically, everything we could know given the words we use is there, over and over, even with copies with only one word changed. But we will never find it or sort out meaningful information.

A cheaper machine probably wont be more capable than a more expensive one, but if you cant pay the cost, something is better than nothing

[@valeriiradchenkov5761]

The absence oh HB is actually advantageous, not just neutral. Most normal fish cant live in very cold water simply because their blood becomes too thick at those temperatures. Icefish have no HB and no red blood cells, so their blood is very thin compared to other fish.
