Jan 1, 2011 · We also calculated the coalescence time of each clade, i.e. the time to the most recent common ancestor (TMRCA), as follows: Clade 1: 406 000 years ago (95% confidence interval 105 400–811 300 years), Clade 2: 334 600 years ago (95% confidence interval 86 100–661 300 years), Somali wild ass clade: 359 500 years ago (95% confidence interval ...
However, for this analysis, we specified the minimum age of 4.05 Ma based on the earliest Parahyaena fossil (P. howelli) (49–51) as the minimum age, the maximum age of 5.2 Ma based on the most recent putative Hyaena/Parahyaena ancestor, I. abronia , and the mean between these two values (4.625 Ma) as the mean divergence time value. We further ...

Glossary. most recent common ancestor. (abbr: MRCA) The youngest common ancestor that two taxa share. On a phylogenetic tree, one can locate the most recent common ancestor of two terminal taxa by tracing each lineage back in time until they meet. The node at which the lineages meet represents the most recent common ancestor of the taxa.
Around 9,600 years before present (YBP), the paternal lineage of E-V32 took shape as it diverged from the common ancestor E-FGC14378 branch. The most recent common ancestor (TMRCA) of this branch is estimated to have been born around 7,000 years before the present (YBP). See it on YTree.
Jul 16, 2021 · In addition, the ARG can be used to estimate the time to most recent common ancestor (TMRCA) between admixed and admixer haplotypes, providing additional information about historical admixture between humans and archaic hominins. Given the utility of an ARG, it is expected that several methods have been devised for estimating ARGs from genetic ...
