But that point is not relevant to the post you replied to, which was wondering aloud about human adaptation to the availability of fish. The availability of algae is the same as the availability of fish.
>I have not seen any study what shows that ALA and LA are not essential.
Have you seen one that shows it is? Because there are none.
>Link please.
I can't find the original study, just people talking about it. They gave up on the original premise as the linseed oil was killing people instead of making them healthy, so they ended up reporting on smoking and blood pressure.

>But some truth is known in 2018.
But people with agendas lying on their blogs or youtube isn't truth. Pretending carnivores are omnivores and then saying "look we're not like omnivores" is just deliberate dishonesty. We are not like carnivores. We are, 100% without any question, omnivores. Read literally any text on mammology, there is no debate, no controversy, no ambiguity. Poor studies like the adventist study vegan advocates like to cite may show benefits when they don't control for anything else. But properly defined and conducted trials show veganism is not associated with lower mortality: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4691673/
