Cyanobacteria don't need oxygen to live, retard.
There was no oxygen until the Great Oxydation.

Why would you need to compare temperature from the time of the cyanobacteria (when there was no oxygen) or from the time of the dinosaurs (when there was twice the oxygen and it was inhospitable to Humans as well) instead of comparing temperature since Humans exist which is what scientists are doing?

>Dyson Sphere
You need to figure out megaengineering, special materials and how to travel at relativistic speeds in order to acquire and mine the staggering amount of resources to build something on the scale of a Dyson Sphere.

Any society seeking to do that, would need to figure out how to obtain insane amounts of energy to do it. Hence, any society that could figure out how to build a Dyson Sphere would have no need for it.

Stop pushing this retarded scifi concept.

Opinion discarded

>1. Chimps (frugivore)
Chimps are omnivores, not frugivores. They eat meat occassionally such as insects or bushmeat. Even cannibalism has been observed among chimps.
>3. Orangutan (frugivore)
Omnivores, like chimps
>5. Crow (omnivore)
Crows have been observed since time immemorial eating human remains after battles. Hence, why we associate them with death.
>6. Pig (omnivore)
>7. Squirrel (herbivore)
>8. Pigeon (herbivore)
>10. Rat (herbivore)
Not nearly as smart as the animals I listed.
My list (>>11935082) is based on current science comes from a combination of:
1. Brain to body mass ratio (all above average)
2. Ability to pass the mirror test (passed by corvids, crows, dolphins, octopus, elephants, chimps, apes)
3. Observed tool use (observed in chimps, great apes, corvids, blue jays, dolphins, elephants, not in octopus)
4. Complex behaviours showing a more evolved theory of mind such as such as teaching their young (dolphins, chimpanzees, blue jays), mourning the dead (blue jays, dolphins, chimpanzees, elephants), or recreation (playing) without a survival purpose (such as dolphins playing with bubbles or having recreational sex)

A single of these criteria doesn't define intelligence but the combination of them paints a pretty full picture.

>According to the meat eating = brain mass theory, we should see lions, tigers, etc at the top.
There is no such theory. There is no unified theory of evolution. There is no goal to evolution. Evolution is driven by random mutations.

If you are talking about observed trends, intelligence seems to favor omnivores that eat meat, but there's always a dolphin (carnivore) or elephants (herbivore) breaking such easy categorizations.

>The smartest animal on the planet mainly eats fruit.
That's us.

>No correlation, totally debunked.
You are the one claiming a correlation.

>Whose transmission method is the same as covid.
The influenza virus is a different size, and from a different family of viruses. This affects the transmission and the effectivity of different mask types.

>They're just posting evidence that masks don't appear to work.
No, in typical schizo fashion you went out of the way to dig up a study from their archives that has nothing to do with the topic at hand, because it deals with a different type of virus, in a different context, and not only that, but the article concludes that proper education on mask usage and hand washing makes a difference in their effectiveness, not that they are ineffective.

>Which kind of undermines any recommendations of masks on their part, wouldn't you say?
No, you took an unrelated study from a random chink researcher on influenza out of context and are trying to make it fit to a whole different situation. The study even has the typical disclaimer saying that the CDC does not endorse the findings and conclusions of the study, a disclaimer that is made specifically for the likes of imbeciles like you.
