the 1918 spanish flu death rate was around 20%. It was only in March 2020 after covid19 was mainstream news it got edited in Wikipedia to show 2% (not sure if that's changed by now), you can check the edit history. But in short, in 1918, there were coffin shortages, compared to the toilet paper shortages with covid19. covid19 and the Spanish flu are not even in the same weight class, not even a little bit, whereas ye…

I agree that some people may think things are worse than they are. I feel like the zeitgeist, at least in my area, is a lingering uncertainty of exactly how bad things are, due to a lack of testing, and of how bad things can get, as we saw in italian and new york hospitals. My understanding, however, is that the transmissibility of covid-19 is 3 to 10 times greater than the common flu. For instance, our local public…

Man, I've always actually kinda wondered about this. I know it's macabre, but I think about human migratory routines and when different groups clashed back when life was so primitive and brutish, they're must've been those tendencies to rape and sexually conquer the opposition. Surely that is reflected in the genetic ledger of time. What a crazy insight. Genetics is such an interesting field. It's bonkers there's jus…

I encourage you to explore the early history of the pre-Roman Empire peoples. These were largely mythologies that the romans retroactively constructed for themselves (i.e. they had the opportunity to omit the raping and kidnapping in retellings, but chose not to). It’s full of “and then tribe X invaded and the land of Y, took their women and enslaved their men”. Back and forth for centuries. This behavior was cyclica…

Canis is the genus. Even barring classification mistakes, cross-species breeding across genus is not impossible, it's just very less likely to produce viable and/or fertile offspring. A classic example is the breeding between Equus Caballus (horse) and Equus Asinus (donkey): it works and you get a Mule. The genetic difference between the horse and the donkey is non trivial, they even have a different number of chromo…

I mean, Canis dates to Linnaeus, so that it's paraphyletic should be the presumption.

> The story of human evolution is full of ancient trysts. Genes from fossils have shown that the ancestors of many living people mated with Neanderthals and with Denisovans, a mysterious group of extinct humans who lived in Asia In the case of Neanderthals, isn't that "all" people rather than "many" people? Neanderthals are believed to have gone extinct 40000 years ago. But there was an article here the other day abo…

Subsaharan Africans are believed not to have any Neanderthal admixture, and the logistics of the spread out of Africa would be a good reason why.

You're overlooking the fact that even if easily breedable pool of foreign species existed along H. sapiens, given enough time they would either be purged or become common ancestors to everyone by now. Since they were purged and exist as remnants in individuals' DNA.

If they are remanants in people's DNA, they did become common ancestors, no? Everyone's family tree collapses to the same individuals at 5500 BC, after the other humans went extinct.(1) That means we are all descended from non Homo Sapiens humans. What I'm trying to say is that they were not "purged," we are their descendants. We got most of our genetic material from the Homo Sapiens side, but there is continuity wit…
