Met Éireann weather maps https://www.met.ie/latest-reports/satellites/world-visible
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.

Presumably this is a function of the time of year, and at the equinox the equivalent longitude in South Africa would the same.0 -

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).0 -
I thought the remark about cumbersome longhand nomenclature in the first section was rather amusingDeleted User wrote: »I looked at the wiki page, and have signed up for a PhD level course.

That bit was one of the few that I actually could make sense of!0 -

I think that will go down as my favourite autologous statement ever!0 -
