[OC] Modern Icelandic DNA points to different origins for the male and female founders
I saw this post on Brazil. https://www.reddit.com/r/dataisbeautiful/comments/1vlyj3f/oc_brazils_violent_past_is_preserved_in_its/
Remembered hearing a similar story about Iceland. I dug up the papers https://pubmed.ncbi.nlm.nih.gov/11179019/ https://pmc.ncbi.nlm.nih.gov/articles/PMC1274484/ Mitochondrial DNA that is almost all passed by the mother does not seem to let you drill down as much so it is more vague 'British isles'.
R package ggplot2 code for this is at https://gist.github.com/cavedave/9fc8f08c897d6abd4ab31aa0bd40d3ae

The introduction of fish to the Scandinavian mountains by hunter-fisher-gatherers 5000 BC
Not Ireland but Norway but really interesting. And it makes me wonder how the brown trout in our upland lakes got there

Average price difference (20:00 - 13:00) in 2026: €75.53
2023: cheapest 02:00 (€/MWh 88.21), most expensive 07:00 (€/MWh 133.95)
2024: cheapest 03:00 (€/MWh 87.16), most expensive 19:00 (€/MWh 132.81)
2025: cheapest 14:00 (€/MWh 71.84), most expensive 20:00 (€/MWh 140.25)
