Humans may have a converging opinion however this is more likely related to the current social norms rather than an anything else.
If you were to transport a person from 400 years ago into the present then you would find their idea of ugliness would be very different from our present opinion.
I agree that sexual selection isn't a new idea, however I would suggest it's more related to what the media and advertising tells us is optimal rather than other factors (e.g. see the changing sexual norms in teenagers due to porn).

Again, no
>> Studies have shown that there is surprising agreement about what makes a face attractive. Symmetry is at the core, along with youthfulness; clarity or smoothness of skin; and vivid color, say, in the eyes and hair. There is little dissent among people of different cultures, ethnicities, races, ages and gender.
Symmetry works across species. Are zebras influenced by the current social norms?

Search for symmetry and sexual in Google Scholar and you'll find hundreds of studies showing that those preferences are obviously innate. Maybe not all of them but a lot of them.

Sure. People find symmetric faces to be more attractive.
A person's physical appearance goes beyond the face. Body shape, fitness levels, etc are all factors in attractiveness, and those preferences have changed over the years, and vary significantly by population. The 19th century Victorian ideal didn't do much for a farm wife of the era.
This woman is remarkable given the challenges she has had to face. I hope she continues to educate those with small minded opinions.
