This DNA is only inherited from the mother.

No genetic recombination occurs for this type of DNA.

This DNA is incredibly small and circular, sized at only ~17,000 bp.

There are many copies of this DNA in each cell.

Starting at 100%, after 704 million years 50% will be left, after another 704 million years nothing will be left.

Starting at 100%, after 704 million years 50% will be left, after another 704 million years 25% would be left.

Starting at 100%, after 5730 years 50% will be left, after another 5730 years nothing will be left.

has not occurred as there has not been enough time since our separation from the human common ancestor.

will no longer occur due to our medical advancements.

can be seen in the adaption of short stocky bodies of indigenous peoples in cold regions.

means there are currently multiple species of human.

Species C is the least advanced.

That E and F are the most advanced species.

There is a closer evolutionary relationship between C and D than C and E.

That C and F are more evolutionarily related than C and B.
