You need to be a member of mtDNA Haplogroup I to add comments!

And, here's a web page from the Smithsonian's National Museum of Natural History which cites studies which indicate that the sequencing in Neanderthal mtDNA was different than that in modern humans.

According to testing, my mtDNA is I2. Curious about its origin, I found the following the following article on the web, which speculates that mtDNA I could be Neanderthal in origin.  I find that of interest, but also wish to continue researching the literature about it. It certainly is amazing what we are learning in our modern day about our genetics and epigenetics.

My mom also has two sisters who have daughters who have daughters.

I received my test results in November of 2012.  I am an I2.  I told my daughter before I got my results, "I hope I don't end up being some very common type."  I guess I got my wish.  I have two sisters who have one and four daughters and some of them have daughters.  Also my maternal great grandmother had six sisters who had children so we have lots of I descendants.  I know that mtdna is more anthropological than genealogical but I think it's interesting that my 2nd, 3rd, and 4th great grandmothers on my maternal line all lived in the Ukraine; the area shown to be the starting point for I mtdna.

Hello! I'm glad to find this group interested in mt Haplogroup I. Thank you, Bonnie! Looking back in our family trees, it may be of interest to see how often our direct maternal line almost ended before we were born. For example, my great great grandmother was an only daughter who, in turn, had just one daughter... but the maternal line did manage to continue to my 11-year-old daughter and my twin sister's daughter. Wow, I see that one member (Bonnie Burdick)'s line with 8 granddaughters will certainly be represented in the next generation of "Iris people."

Bonnie Schrack I've seen you on the HG I for years now. I guess there are very few of us in this catagorey so I might as well 'join'. Llucky me . I have 5 daughters and 8 granddaughters so there will be more of us "Iris" people.

Thanks, Bonnie, for getting this going.
