Down and Right would be South and East surely !

The Atlantic portal is further west than the Pacific portal!

To answer that question we'll need another three pages about the British isles

Financial wealth, such as that held in stock, for the richest 1% was greater than for the bottom 80% of the population. https://www.ft.com/content/d52743ca-c669-4c71-941f-8281230a21b5

Frequency of blue eyes is strikingly similar to frequence of lactose tolerance:

Statistics like this are usually done on the basis of residence, not citizenship. So, of all the wealth held by UK residents, you compare the wealth held by the top 1% and the bottom 8%. Wealth owned by non-residents is omitted from the calculation.

You ignore citizenship. (Typically, in fact, the data sources on income and household wealth won't have recorded citizenship, so even if you wanted to do this on the basis of citizenship it would a difficult statistic to assemble.)

And, just to add, we could be looking at this on the basis of individuals, or on the basis of households — i.e we could be looking at a claim about the wealthiest 1% of UK individuals, or the wealthiest 1% of UK households.

Not unless they were practising dairy farming. Which - oversimplification coming - they would only do if they were lactose-tolerant.

Human infants and children generally have no problem with lactose (which is fortunate, given how we nourish our infants) but the lactose-intolerant tend to lose the capacity to digest it in adulthood. If you don't lose it in adulthood, that's because you have genes which give you the enduring ability to digest lactose. Natural selection will favour these genes in a population that lives in an environment where a limited inability to lactose is going to unduly restrict your diet — the lactose-tolerant will be better nourished, enjoy better health, live longer, have more children, so with each generation the proportion of the population that has the lactose-tolerant gene rise.

So, in a Mediterranean region, you can get dietary fat from olives, calcium from almonds, figs, seeds, fish, etc; you'll do just fine without much dairy in your diet. Whereas if you live in, say, Norway, there aren't a lot of olives, almonds or figs to be had, and milk and butter are quite important. So the lactose-tolerant have an evolutionary advantage in Norway that they don't have in Sicily.

(In fact lactose-intolerant people can eat dairy foods, but they will generally process them first to reduce the amount of lactose in them, e.g. by fermentation. So lactose intolerant populations do practice dairy farming, partly to produce food for their lactose-tolerant children but also to produce processed dairy foods that adults in the community can consume.)

Then again you can always eat the animals, instead of drinking the milk.

Red hair map of Europe.

People with red hair and blue eyes are only 0.17% of the worlds population.

At a later date they also became very important: the word chattel has a similar origin to cattle, in Ireland you have the cattle raiding/rustling stories and Boru (from a certain king) means cattle tribute.

I had read about a hypothesis that the Rathcroghan area in the midlands is very important and that the UiNiall made Tara more prominent to suit them, so you have the weird midlands route.
