Hello Jonathan, I think you made a good point when you mentioned how breeding within a small population would lead to genetic defects. As we covered before, one problem with eugenic ideals, aside from morality issues, would be the limited genetic information available for safe reproduction. If one were to believe that a population has remained “pure” after many years, then the resulting generations would show multiple genetic defects. The article worked forward to defend the conclusion that migrations caused a mix between the many different societies which dismisses the concept of a ‘pure’ European. The reasoning used past evidence from reliable observations that occurred through several migrations at different time periods to validate the
