FamilytreeDna has increased its YDNA-based reporting since last seen and is now state of the art in YDNA science. Below is a comparison based on my own SNP mutations to ancient samples. Ancient samples are now new in FamiliyreeDna's YDNA reporting. The two samples closest to me that have been successfully classified are Ladogan Viking sample VK220 and Viking Age Sigtuna sample 84005/nuf005. Interestingly, I have previously tested the latter sample with the Eurogenes G25 test and it was found to be partly Finnish. I have personally tested both samples for the CTS2208 group. FamilytreeDna can reach the slightly more accurate classification Z26344, which is a new classification found after my own test. I'm going to try repeating the test at a lower quality level to see if the test shows any new results. Additional mutations between 800 BCE - 1200 CE are likely, but the result depends on the sample quality.
Anyway, I'm happy with the results. When the TMRCA to me is 800 BCE (age of CTS2208/Z26344) for these two and the oldest Finnish I-branch with certainty is 2200 years old (FtDna), then only 600 years of unexplained time remain in between. The next major upstream from the Finnish clade is CTS7676 and isn't identified by Finnish samples. CTS7676's TMRCA in Sweden is 2600 years (FtDna). With it the difference shrinks to 400 years. This is amazing. By modern samples CTS 7676 is purely Swedish (Yfull 24 samples, of which 22 are from western Sweden, can also be read as Norwegian in that period) and its closest branch to the downstream is Finnish L287/L258 as mentioned above. So the transition time from Sweden to Finland has been 400 years (look the picture below, made by FamilytreeDna), which dates to the very end of the Bronze Age and to the pre-Roman Iron Age.
During that time, cattle breeding and farming became a new way of life on the west coast of Finland. There was small-scale farming in Finland before, but livestock farming in this area was a typically Scandinavian way. Burials became barrow grave burials and stone cist burials. Connections with Scandinavia became more common. It is estimated that the Finnish language came to Finland 600-1000 years later. According to the estimate, the Sámi arrived in 500 BCE, that is exactly that period, but they came from the east. The economy based on agriculture and cattle breeding has not been connected to the Sami people (need to be checked). The Sami language is dated to be older than this period and the origin in the Urals. They have preserved their language to the present day. The Germanic loanwords of the Sámi language date to this period.
This was an exceptionally long text from me. Thank you for your time and reading. This subject is important to understand later Finnish history.
______________________________________________
Z26344 is an immediately downstream mutation for CTS2208. FamilytreeDna dates both to 800 BCE. It is safe to say that both seem to have a Swedish origin (see my previous post and older posts -> link). FamilytreeDna really puts things into perspective.

Edit 12.11.24 20:40
After more intensive searching at FamilytreeDna I found a picture showing that 84005 and VK220 diverged from the ancestral lines of Finnish L287/L258 soon after the CTS2208 (it will say around 700-800 BCE.

I corrected some TMRCA-values and for consistency with datings I ended up to use only FamilytreeDna's datings. FamilytreeDna has much more samples for TMRCA calculations, but their data confidentiality rules prevent me use their sample data. Yfull reports sample ids and ISOGG classifications. Sorry about inaccuracy in my original text. It happens when you try to combine information from multiple sources, plus building logical and coherent texts in foreign language isn't as simply as using your mother language. I hope that now datings and text logic are fine.
