The Curious Origin of mtDNA Haplogroup B2 in the Americas

Since the publication of Paternal origin of Paleo-Indians in Siberia: insights from Y-chromosome sequences I have found myself contemplating the migration or migration of maternal lineages to the Americas. Generally, researchers have considered the timing to be deep, around 18,000 years ago.

H & HV mtDNA Project - 5 July.

mtDNA H & HV Project – Weekly Update 5 July 2018

I am going to keep things short this week, because I think the one topic I am covering is really important for us to understand. I am looking at the country of origin data for the project. This shows one of the limitations of the project and the FTDNA matching database.

The Encyclopedia of mtDNA Origins – Resources & Citizen Science

I am continuing my work on the Encyclopedia of mtDNA Origins from last time… Today, I am working on the final requirement in the project to create mtDNA pages for all named branches of our shared maternal tree. It is a list of additional resources to help the user understand and enjoy their results.

The Encyclopedia of mtDNA Origins – Sources, sources, sources

I am continuing my work on the Encyclopedia of mtDNA Origins from last time… This is a project that will create mtDNA pages for all named branches of our shared maternal tree. This time I will talk about the ninth requirement, a list of academic journal articles that mention the branch.

The Encyclopedia of mtDNA Origins – GenBank data

I am building the table for mtDNA sequences from GenBank. GenBank sequences are the main source for defining branches on the maternal tree. Therefore, they help us understand not only the origins of a branch but the current structure of the tree — what we know and its limits.

The Encyclopedia of mtDNA Origins – Geno 2 Samples & Maternal Origin

This is a project that will create mtDNA pages for all named subclades. One part of each page will hold a table of results from National Geographic’s Genographic Project’s Geno 2 results. The combination of accademic sample collection and public participation, the Genographic database is one of the largest sources of mtDNA result with maternal ancestry information.

The Encyclopedia of mtDNA Origins – Phylotree History Log

I have been working on the part that shows the current and historic definitions of a branch under Phylotree. From the first post, we have a user story –What the user wants. As a user with mtDNA results, I would like to know how the named branch is defined in the current Phylotree build and has been in past ones.

The Encyclopedia of mtDNA Origins – Background and Summary Information

Continuing from my first post on the Encyclopedia of mtDNA Origins… After learning the basics of using the Pods framework to create custom post types, custom fields, and templates to present them on webpages, I decided to create an mtDNA stories custom post type.

For those who don’t know Wordpress, post types are different types of web pages. All pages of the same type share a common set of fields and features. Creating a type lets one add additional parts that only make sense for some pages.
