"The guy who doent care and will lay anything and anyone has 17-odd illegitimate children, therefore his genes are the ones thriving and outnumbering Mr I-Need-The-Highest-Value-Woman-So-I-Will-Keep-Searching-Forever. His genes are gonna die with him, and good riddance."
Is a strong argument that directly addressed what Darwin said.
As for the "criteria for what is attractive", well, Ruben's paintings show what was considered the ideal beauty for women at his time.
You might notice that the ideal beauty standard in his day was women with cellulite. Which is opposite to the ideal beauty from Sports illustrated. And then you have the bounded feet that chinese used to find attractive, the long necks of some African tribes and plenty of other examples.
That is why they talk about knowing about anthropology, because it is a myth that is easily debunked once you start using google to read about the topic.
I encourage you to read more from different sources, where discoveries about how people used to live are discussed. From women who were buried with their weapons, to men who used makeup, to art depicting how people lived. It is a known fact that Cleopatra won't be considered beautiful by today standards. Yet, she was considered very intelligent and cultured, which made her "the most attractive woman" of her time.
The more you read from different sources, the more sense what she is saying would make to you and the less sense evolutionary theory would make to you.
This is an old classic that is usually recommended for divulgation:

You probably can find it at your local library. But maybe other people can recommend better reads to start.
