Biology

The pattern of genetic similarity and differences among humanpopulations allows us to reconstruct the evolutionary history ofour species. Label the lettered parts of your answer.
A. What taxonomic group would include L1 + L2 + L3, but notHomo sapiens neaderthalensis?
B. Where and when did that (L1 + L2 + L3) taxonomic grouporiginate?
C. Was there ever any interaction between (any part of the)taxonomic group you named above and Homo sapiensneaderthalensis; if so, what was the nature of thatinteraction?
D. Drawing on the information in your answers to parts A, B, andC, and on patterns of current human genetic diversity, explain thesequence and timing of events that led to the present situation,with a single kind of hominin occupying the whole planet.

Today the oldest mtDNA haplogroups are found in Africa The first haplogroups were L1 L2 and L3 and they gave rise to other macrohaplogroups and branches of the global phylogenetic tree during the migration waves from Africa all over the world Haplogroup L3 is ancestral to macrohaplogroups M and N They arose in northeast Africa and spread into Europe and Asia Haplogroups H I J N1b T U V W and X derived from haplogroup N and at present they comprise the majority of mtDNAs in Europe The Asian haplogroups A B C D F and G derived from M and N Haplogroups A See Answer
