Originally the pub. But through common usage, now the area as well.

This has most likely been posted already but seen it myself for the first time today.

The 'World Visible' one is interesting, as it shows that it is sunrise in Ireland, but in much of Southern Africa it is still nighttime - despite it being further east than Ireland.

A range of other maps are available from that page.

Rotate the image by 23 degrees, the average tilt of the Earth's axis from its plane of orbit, and you'll see why.

Pretty sure that map is showing sunset in ireland, not sunrise, unless the sun rises in the west??

I rotated the image 23° and now Southern Africa is even further east!

Presumably this is a function of the time of year, and at the equinox the equivalent longitude in South Africa would the same.

Boards has been terribly slow for me for days and I have suspected a DDOS attack might be in progress. Earlier today Airwire were being attacked.

As a result of looking into this, i cam across this interesting DDOS atatck map: https://www.digitalattackmap.com/#anim=1&color=0&country=ALL&list=0&time=18383&view=map

if somebody could explain that chromosone map to me it would be appreciated.

If I'm correct, some of the people in that area have a chromosome group that no other humans have, suggesting they are the first branch in the human genetic tree. They are the least like other humans.

Of course, with modern movement these things then get intermingled again.

That haplogroup represents YDNA Adam (mutations that are carried on the Y chromosome and passed from father to son only), and is dated to approx 250,000 years. The next "branch" is A and is 80,000 older.
As mentioned subsequent movements confuse things and frequency in modern populations represent sinks not sources, but given the spread and what is known in the fossil record etc it adds to the idea of an African origin for humans.
The wiki article has a good overview and the second one gives a more interactive look at the entire YDNA tree.

I looked at the wiki page, and have signed up for a PhD level course. I understood about every third word. The next third, I understood, and the last third I thought I understood but clearly didn’t.

National Geographic had a good explanation but I can't find it now, the science snowballed in the last 10 years. At the start, the group that most Irish males belonged to had about five branches, now it's in the dozens (if not hundreds).

I thought the remark about cumbersome longhand nomenclature in the first section was rather amusing

That bit was one of the few that I actually could make sense of!
