Hey,
When you assess the attractiveness of the opposite sex, be it male or female, do you also assess whether they will produce healthy and 'strong' offspring. I know that when I look at someone attractive I ponder whether both mine and their attractive traits will be passed on to their offspring to produce an attractive child.
I live in an area with a very narrow gene pool. It's disgusting. I get on the bus to school and see some of the monstrosities that are human. Some have no teeth, fat and speak with a slurred accent. You often find these specimens working at the local supermarket and doing other remedial jobs. This poor gene pool is self perpetuating i.e. Their children will inherit similar 'weak' alleles and thus, a population with little genetic diversity is formed. This is the reason why I promote immigration because ethnic diversity expands the gene pool and allows offspring to have the best possible chance of survival. Diversity is key for the continuity and development of our species.
To those of you who are narrow minded, please expand your mind and answer this question when seeking a partner: "Does he/she exhibit dominant characteristics that, which combined with mine, will produce a child with a diverse range of genes ensuring it is strong and healthy."
I know my assertions are to some extent, illogical and flawed. Some of the greatest minds originate from genetically weak backgrounds. However, it's worth identifying that during the Renaissance, travel and communication became easier and thus; increasing diversity, especially throughout Italy and parts of Europe. I have noticed a huge gap from the Macedonian empire (ancient Greece) to the Renaissance. The Medieval ages had very little innovation in terms of scientific discovery and human development. There are many factors as to why this is so. However, diversity is to some degree, relative to geographical location. Greece is situated in such an area that makes traveling to regions which vary in diversity greatly, possible. North Africa (Egypt) for example.The Roman empire succeeded the Egyptian Empire and thus; the diversity increased significantly and 'Roman genes' were infused with 'Egyptian genes'. This could explain the huge increase in intelligence and why many Philosophical and Scientific discovers were made during that time.
This theory is highly speculative. It is only an observation!
