Yesterday the Eaton Lab at Columbia University announced on Twitter a nifty little tool by Carlos Alonso Maya-Lastra called TreeToM, which accepts Newick trees and CSV latitude/longitude data to explore phylogeny and geography interactively, with no coding required.
I thought it could complement nicely my All Ancient DNA Dataset, particularly for those newly described SNPs (FTDNA private variants, etc.) that have not been incorporated yet into SNP Tracker.
Here are two examples with snippets to copy&paste to the appropriate boxes in TreeToM. Feel free to add others in the comments:… Read the rest “Visualizing phylogenetic trees of ancient DNA in a map”
Open access article The peopling of the last Green Sahara revealed by high-coverage resequencing of trans-Saharan patrilineages, by D’Atanasio, Trombetta, Bonito, et al., Genome Biology (2018) 19:20.
Little is known about the peopling of the Sahara during the Holocene climatic optimum, when the desert was replaced by a fertile environment.
In order to investigate the role of the last Green Sahara in the peopling of Africa, we deep-sequence the whole non-repetitive portion of the Y chromosome in 104 males selected as representative of haplogroups which are currently found to the north and to the south of
