Question

1) Molecular genetics has revolutionized the ability to trace family

history (you may have seen this advertised on television or the web). Mutant alleles that predispose to diseases such as cancer can similarly be traced back to the original populations in which they arose. In the history of Scotland, the "highland clearances", as they were later termed, led to many Scots being evicted from their lands and then emigrating to North America and Australia. The forced "clearances" resulted in a drastic population decrease in Scotland prior to rebuilding the population that is present today (little immigration occurred as the population rebuilt over 150 years). Similar events occurred in Ireland, and the migration of the Scots and Irish around the world is well known.
Explain based on what you have covered in class and lab about population genetics, how these historical events (covered in your history classes at school and college) would impact potential health issues in the present day populations of Scotland, Ireland, and the countries to which the displaced Scots and Irish migrated.
2)     Is there a name for the effects of population crashes and its effects on evolution? Explain how this concept is different from natural selection. 
3) What is the most realistic way for evolution to occur among populations? Explain your answer.
