DNA Live! - Your Questions Answered

Q. With ancestry introducing new tools, as well as myheritage etc. What do you think the next advancements will be in DNA genealogy? Regardless of companies.

I've just seen this since I had a computer meltdown when this was live. I might have an explanation for Regerio. Since there is Portuguese on both sides, the Middle Eastern could be Sephardi converso who came to Brazil in the 15th and 16th century.

From Madeira Island Portugal?

Haplogroups can be useful in proving several separate families with the same surname or similar surname in a geographic area are definitely related. I have four distinct Ross lineages traced back to Greenville and Laurens Counties of SC in the early 1800s. We haven't identified the common ancestor. However, folk descended from four different ancestors are cousin matches across the lines in Ancestry. Such hints at descent from a single Ross ancestor. I've tested nine males within these four Ross lineages. All share the same haplogroup identified by a phylo-equivalent group of SNPs. Furthermore, this haplogroup is also comprised of two separate subclades, which are descended from the primary haplogroup. Therefore, without a doubt, these four Ross lines all descend from a single male ancestor surnamed Ross. I am currently working to ascertain if a 5th Ross lineage in SC shares our Y-DNA haplogroup...

I wouldn't say they are definitely related (unless you are talking about going back to the origin of the haplogroup as the MRCA), but it is evidence of a potential relationship.

Q. there are 8 dna matches that match me, they all have a common ancestor. Is it likely that common ancestors name is my ancestor?

[@williamstansell8612]

On my mom's side of the family I haven't found any matches with DNA, like for insects there is a family called Randy but there also one called Ramsey want I like to know is they one in the same and the DNA has not told me anything yet and I a cousin that has the same question.

Q. I have family history on the websites back five generations on all lines.. I would like to see which line is my Jewish ancestor.. ancestry DNA tells me it is on my my father's side and is on a good portion of chromosome 9 and 20.. I understand that I can do that using a chromosome browser.. I also have DNA tested by FTDNA.. and I have another question about Y DNA if that is a topic.

@Family History Fanatics, Q: Can DNA be used to confirm or disprove Human Common Ancestry back to Chimpanzees or Amoeba?

[@NorsePJ]

Yes. DNA shows our ancestry is linked with Chimpanzees. Both humans and chimpanzees have endogenous retroviruses showing up at the exact same location on the DNA strand as each other. This doesn't mean that we come from chimpanzees, but rather that we have a common ancestor. Let me give a simple example of how this works, with regard to the above. Let's say a man who lived 500 years ago was subject to a serious virus but survived and had children. And then now, 500 years later, they find this man's remains and do a test on his genome and discover within its DNA sequence there's a reference to this virus at a certain point. And then, let's say you and I both decide to have our DNA checked, and let's say they discover that along our DNA strands, at the exact same point as the man above, there is a reference trace to this virus. Would you say that it's a safe bet that you and I both have this man as a common relative or ancestor? There is no question, even with just using DNA as evidence, that we have evolved through the means of evolution.
