Student’s Name: Professor’s Name: Course Code; Date: Archaeology Question 1 DNA is crucial towards tracing our origin as human beings and how our ancestors migrated across the earth surface. DNA also helps us to understand the ways we are related to each other as human beings and animals such as chimpanzees. Scientists assert that the modern human beings trace their origin back to two hundred thousand years back in the continent of Africa. They began their migrations about sixty thousand years ago. Some moved to America some to Asia some contributed to the modern mtDNA gene pool. Question 3 Even though timing of the molecular clock is a helpful tactic in determining the time in prehistory when two or more life forms diverged is degree of accuracy is questionable. This technique uses mutation rate hence it requires the biomolecular data that is used in calculating the nucleotide sequences for the amino acid or the DNA sequences for protein (Kimura Motoo 56).

Order Description:

How has ancient DNA studies contributed to our understanding of human migration? Discuss some of the types of DNA analyses (e.g. x, haplogroups, mitochondrial) that have been employed. What biomarkers or sequences do these analysis trace and what information do they provide? What are some of the issues with the timing of the molecular clock?
