Mitochondrial Evolution & Speciation

Mitochondrial Evolution & Speciation

We are beings whose consciousness flows through and is experienced by biology. The biological tools we have with which to experience, work in, and transform the physical world are those we inherit from our ancestors. The biological tools we inherit are those we bequeath to our descendants.

Importantly, as it has in the evolutionary past, speciation (the process by which biological populations evolve to become distinct reproductively isolated species) may ultimately in the evolutionary future be driven by maternally inherited mitochondrial biological mtDNA genetic lineage(s) as well. New research supports the idea that mitochondrial evolution drives speciation. 

A glance at the basic mtDNA genetic phylotree suggests that L3 mtDNA lineages (the ancient ancestral mtDNA lineage from which my own U5 lineage descends) is one rapidly evolving macro-lineage. In the future, it may be that L3 lineages may evolve into a distinct human species, while the L0, L1, L2, L4, L5 and L6 macro-lineages may group together to form a second distinct human species. As in the ancient past, the future earth may again be home to multiple human species.

All L3 lineages (even those in Africa) are genetically close to modern Eurasians, while the L0, L1, L2, L4, L5 and L6 lineages are genetically close to modern Sub-Saharan Africans. I think science supports that mtDNA haplgroups L and L3 arose in Southeast Asia, while L0, L1, L2, L4, L5 and L6 arose in Africa.

Below are the mtDNA lineages considered to be the European lineages. My own general lineage is U5b1. More specifically, though not shown on the chart, my own mtDNA lineage is U5b1b1-T16192C!
