As far as I know, the story recostructed from fossils and genetics is like this:

  1. Genus Homo evolves in East or South Africa from earlier bipedal apes (e.g. Australopithecus) between 2.5 and 2 million years ago.
  2. First out-of-Africa migration by Homo ergaster/erectus, which uses knapped stone tools and fire but still has a noticeably smaller brain than ours, about 1.5 million years ago. Populations migrate into tropical Asia ("Peking Man", "Java Man", the "Hobbits" of Flores). All or near all the ancestry of modern humans comes from the populations that stayed in Africa.
  3. Second out-of-Africa migration by Homo heidelbergensis, which makes wooden spears and builds early shelters, 800-500,000 years ago. This wave gets much farther north, and eventually spawns the Neanderthals of Europe and the Near East, and the Denisovans of north-central Asia, but still never leaves greater Afro-Eurasia. The much more primitive ergaster descendants are completely replaced, surviving for longer only on islands.
  4. Our own species, Homo sapiens, appears somewhere in Africa between 300 and 200,000 years ago. After 100,000 years ago or so it starts developing modern tech like spear throwers and stone arrowtips as well as the earliest abstract and figurative art. The ancestors of San, Hadza, and Pygmy peoples split off from other modern human populations. Meanwhile, Neanderthals and Denisovans develop into their late form and exchange genes.
  5. Third out-of-Africa migration by Homo sapiens, with an abortive migration through Egypt into the Near East 100,000 years ago and then a crossing from Ethiopia into Yemen 70,000 years ago. The wave first follows the tropical coast of Asia, absorbing some Neanderthal and Denisovan DNA along the way, into Australia. A "ghost species" of which no fossils are known leaves behind some DNA in Subsaharan populations. After 50-40,000 years ago the Eurasian populations start moving northward, crossing further with Neanderthals and developing technology suited for cold environments, and eventually crossing into the Americas.

I suppose in the end the answer seems to be kind of an Hegelian synthesis of multiregionalism and out-of-Africa, but I'd say the latter wins on balance.

To be fair, the first story at least showed a downside of Holmes' hyperspecialization: to leave some empty space in his memory, he gave up on ever learning any non-crime-related fact (such as that the Earth revolves around the Sun).

This, of course, is exactly the same thing that leftist, or members of any other group, tell themselves -- when They break their stated principles for expediency, it's because They are treacherous faithless hypocrites; when We break our stated principles for expediency, it's because We really need to play dirty to win. As for principles like tolerance of differennt ideas, freedom of speech, or body autonomy, approximately nobody gives or ever gave a damn about them; a smattering of individuals here and there may care, but in practice they are ad hoc weapons against customs or laws one doesn't like.

We have plumbed the depths of the ocean to only discover funny fish and our stars are just gas and rocks.

IMO that "just" is doing a lot of work there -- what discovery couldn't be dismissed as "just [containing category]"?

Group selection, AIUI, only works when selective advantage for groups traits is stronger than selective advantage of individual traits. This is generally not the case because 1) individuals reproduce faster than groups and 2) individual heredity is much more reliable than group heredity. Strong pressure on groups is not necessarily sufficient to counter these two factors. That said, the situation is different if the group selection is in fact kin selection, in which the component individuals of a group have a high probability of sharing the genes being selected for.

I'm not convinced of that; pessimistic estimates quite easily result in fewer than 1 advanced civilization per galaxy.

There was plenty of lying, scheming, manipulating, and cheating in times and places when theistic faith was most ascendant. Do you think Renaissance Italy, the Holy Roman Empire, the Abbasid Caliphate, and the Ottoman Empire had none of that? Members of the Sicilian Mafia all consider themselves scrupulous Catholics. You may say they are not, in fact, good Catholics (and I would agree, and AFAIK so does the chief of the Catholic Church), but convincing them that God is watching them would not stop their crimes, because they already believe that. People usually think their behavior is either righteous or at least justified by the circumstances; the thought does not become "I better not not burn down that store, God would punish me"; it becomes "Let's burn down that store, it's what anybody would do in my place, actually it's a pretty good idea, God will be happy I'm not a pushover".

You just need to coordinate society such that

"Just"? Pardon me, but you might as well say that to lift mount Everest you just need to push up very hard.

I don't suppose anyone in this thread is going to consider the idea that attractiveness is largely subjective? This discussion feels like reading "Bananas are delicious, if you disagree get your head checked!" "What are you saying? Bananas taste vile, you idiot".

IMO that's an interesting but rather strange objection. Doesn't the presence of angels and demons require more flaws in the scientific understanding of physics than fast interstellar travel, not fewer?

The Fermi calculation is a multiplication of numbers most of which have an uncertainty that spans several orders of magnitude. One can derive any outcome from "there's a civilization in 99% of star systems" to "one civilization every 10,000 galaxies" just by using more optimistic or pessimistic numbers.

I don't believe in God either and my answer would be:

I would very much rather not get murdered, nor any of my loved ones or people I respect get murdered. I generally would like to live in a society with as little murder as possible, trading off with other considerations (e.g. the cost of law enforcement). This would also favor various things I vaue in addition to not-dying. I can also expect most people in my society to have similar preferences, but inolving different sets of individuals; it is fairly easy to collectively agree on a policy of "no murder", but not on one of "no murder of people orca-covenant likes". Every exception I carve out for myself, other people can carve for themselves. (Since people may have different preferences, the general principle is actually a policy of respecting people's preferences as much as possible, with not-being-murdered as an especially strong and stable example.)

In accordance with utilitarianism-but-not-the-dumbest-type, I also oppose murder in edge cases where it lead to short-term benefits, except in ultra-edge cases where 1) it has disproportionately large benefits (e.g. kill Hitler to end the Holocaust), 2) it's not possible to achieve the same benefits without murder, and 3) both 1) and 2) can be known with a very high degree of confidence, taking into account how often people are wrong about them (so, in practice, basically never).

Infanticide was plenty common even long after Christ, possibly as late as the 19th century. But zoophilia? I'll admit I don't know of any society in which sex with non-human animals was widespread and accepted. The two instances I can think of are some cases of damnatio ad bestias in the Roman Empire (but that was intended to be a gruesome punishment, and probably worked as spectacle because it broke taboos) and a certain Vedic ritual in which a queen had to couple with a sacrificed horse (but that was a very specific and probably very rare ritual, and certainly not something widespread in society).

Why should nice people who happened to catch jury duty need a splash of Smith's blood on them?

Because they're the ones who voted to spill it, presumably.

Killing a billion people would presumably make you several additional enemies among the people you didn't kill.

I happened to be in China for work last summer during the national holiday -- anniversary of the founding of the People's Republic -- and to my surprise there was not a single mention of Mao, or any other specific figure, neither by name nor by image. The only words plastered everywhere were a thoroughly innocuous "I love China". His face is still on the money, of course, but physical cash is being phased out fairly quickly.

Ah, nevermind, then. Thanks for the context.

Might be a definition issue. Obviously I don't know the specifics of that discussion, but the person might have meant "useful" as in the "all models are wrong, but some are useful" (i.e., "useful" in the sense that they can be used to build theorems on or make falsifiable hypotheses), rather than in the sense of "having practical applications". If so, I'd be tempted to agree.

That seems extremely dependent on fads of the time and initial axioms, honestly (which divine authority are you going to take? On what subjects?) -- are experiences of divine revelations less tied to what is currently popular than experimental results?

It seems to me that you arrive at whatever is convenient to the politics of the time, since Reason can be used to justify practically anything well depending on your starting priors.

Not wrong, but what alternative is there to Reason that is independent from fads of its time and from initial axioms?

This is a very interesting argument, but I don't think "if it's acceptable for people to voluntarily perform an action for money, then it must be acceptable to force them at gunpoint to perform that action in the most dangerous possible conditions with no compensation" would be considered compelling for any line of work.

If we're discussing progressives, then we need to explain why they feel justified in saying certain type of gross behavior should be illegal when they've spent the last few decades telling us that people behaving in a gross manner should not be jailed or discriminated against.

Because in this case they see a reason other than grossness to make it illegal. It is certainly a progressive tenet, although one that many people who call themselves progressives often forgo, that one should not be punished only for behaving in a way that others find gross or distasteful. It does not follow that no behavior that others find gross or distasteful should ever be punished. AIUI (might be mistaken), the Bible forbids murder on the grounds that it offends God to destroy something that is created in His image. This rationale makes no sense if one does not believe in the divine creation of humans. Nevertheless, people who don't believe that still have reasons for wanting murder to be forbidden and prosecuted. It does little good to say "But you're fine with sinning against God's creation in this case [eating blood pudding], so why are you not fine with sinning against God's creation in this other one [mass shooting]?"

Genetic problems from incestuous relations is a problem. There is no comparable problem for people of one culture interacting with people from that same culture.

I don't know. The physical problem with sustained inbreeding is the pathologies that occur when recessive genes with the same harmful mutation are paired together, and low genetic diversity in a group makes it more vulnerable to pathogens and less flexible when conditions changes. It's not absurd to make an analogy with cultural and social diversity. If people get all their memes from the same metaphorically-inbred pool than deleterious memes are harder to identify and lose, and it becomes harder to generate new ones. A society with low cultural and intellectual diversity would allow viral memes to spread more easily, would be very vulerable to social pathologies that different societies could avoid, and would have fewer resources to deal with changes in circumstances.

Problem is you have no way of telling which action results in less suffering.

It's certainly easier to check, with a confidence high but lesser than 1, whether an action results in suffering than whether it's inherently Virtuous or whether God approves of it.

then your definition of honor is so selective as to be meaningless, and I suspect it really just boils to people you agree with

If the goodness of a cause is too subjective to judge people from, what makes honor any better a standard? The concept of honor also varies quite a lot from time to time and from place to place -- it's not like one can't construct a coherent definition of honor that does not include Lee's conduct.
