Why did the human species diversify phenotypically so much a few thousand years ago? Why has that process stopped? Why was change needed then, not before, not after? Humans have continuously inhabited Europe for the last 40,000 years

I was chatting with an early modern human paleo expert and asked them about this, surprisingly they thought the Toba theory was likely incorrect. There was no environmental change above or below the ash beds emplaced by Toba. There was a climate shift from a stable, hospitable climate to a highly variable one with much less access to fresh water, though they didn't know what caused it.
Here's a real kicker though: the humans before and after this instability had much better tool usage. From rocks gripped in hands to finely knapped spear heads.

The out of Africa genetic bottleneck as well as the tobacco bottleneck have both fallen out of favor. These theories fail to explain the persistently low genetic diversity inside other archaic hominid species, who we know didnt go through an OOA bottleneck, and in fact Neanderthals existed in Europe for 400k year, far more than enough time to erase any bottleneck from their population history and regenerate the gene diversity. Denisovans are a similar case. We only discarded the theory after we realized that most human groups outside Africa (save for native americans) dont actually show evidence of a major bottleneck in their genes.

What we now believe is that there might be some kind of fundamental tie between genetic diversity and the human brain, like schizophrenia and mental illness. Or it could be due to selective sweeps.

Australian aboriginals had a bad run if you follow their migration and separation from other humans across the islands, new Zealand and then eventually across to Australia.

No animal to domesticate.. no native crop.. kept them as hunter gatherers and nomadic.. evolution stalled.

It's racist to say that for some reason but it's clear to anyone who's studied the migration and events.. they're just a fair chunk less evolved

Technically you only need a drop of nonhuman blood, then selection could take place for certain profitable (for the area) traits. We already have a bit of evidence for this as Neanders have gifted different traits to different groups of people, which sometimes affect phenotype.

an objective observer would conclude that the left and right faces are very similar. For example, a lion would see no difference between left and right except skin color.

The reason you think they look different is because humans have advanced facial recognition software built in and also sexual attraction/selection software making them appear radically different. Deep down we're all pretty much the same

Because the part that's evolved to distinguish different faces is impaired. It makes no statement about the level of difference in peoples faces. People with this condition do not struggle with distinguishing between other similar things it just applies to faces. You can't make the assertion that coz some people can't recognize faces therefore there are no significant objective differences between faces.

Yes it would as that is the part specifically made for that purpose. Other parts of the brain can't compensate for that part not functioning as they are not made for that task. It's like asking the visual cortex to compensate for the amygdala. The reason we are able to distinguish the small differences in peoples faces and have a special part of the brain for that, is because for >99% of our evolutionary time we have lived in small homogeneous groups with very similar facial structure. We evolved to distinguish between family members so it's overkill when we are talking about people separated by tens of thousands of years of evolution. So you can't infer that because we need a special part of brain for that task there is no significant difference between facial features.

Let's split this properly.

On one hand the left in the original image is clearly both older, and had a much harder life than the one on the right.

That said given equal age and equal footing, why isn't the aboriginal equally attractive as the blonde chick? Is it social programming or is there something fundamentally more attractive, and if so why didn't the Aboriginals select for attractiveness?

if what is attractive is genetically determined, perhaps the abbos have mixture of groups (denos and neander for example) and they have inherited the 'attraction' of those groups rather than the basal human one. This could explain the lack of selection for 'beauty'. Do abbos find white people to be more attractive? Obviously no human is pure, as we all have admix from other hominins but I wonder if the 'european' look is more like the basal look of human beings. We all have admix but it seems at least so far like europeans have the least admix of anyone, but of course we may discover many other 'ghosts' in the genome from other hominids. This would kind of explain, ignoring all social arguments, the relative attractiveness of euros to other people. Of course a lot of this could be just trading robustness/gracility depending on your situation. Gracility is more attractive to men as women already have this in comparison to men, robustness is more attractive to women, but a more robust design often results in lack of social capitol (due to monkey brain) and so women aren't interested.
