Biology of the Female Attraction to Male

It has been explained from a biological point of view how females and males are attracted to particular features of each other.

For example, females are attracted to males with broad shoulders because it indicates strength and the ability to protect the woman and her offspring. Women are attracted to the muscular body of a man because it means the ability to work hard to provide for his female and secure health of her offspring. Women are attracted to males with facial features like square Jaw and thick facial hair as well as body hair because it indicated a higher level of testosterone and virility.
Females are also attracted to men with muscular round buttocks because it indicates strong thrust and securing fertilization. It is also known that women have a hidden sense of smell which recognizes and attracts them to males of distant genetic relation more than genetically related males which guarantees a better gene pool for the offspring. Mainly a woman is physically attracted to men features which ensure the security, safety, and survival of her and her family as well as better genetic characters for her children.
In our modern society, survival and safety do not depend on bodily strength anymore. However, now survival depends on status and wealth. Status and wealth are achieved by success and or intelligence. The biology of love and attraction has changed with time and women are maybe more attracted to smart, successful men than strong or good-looking men.
When my wife was asked "Why are you attracted to him" She said;

"When I met my husband I found him very attractive. He has broad shoulders, V-shaped body, strong muscular arms, and a smooth firm butt. I was attracted by his facial features especially his nose. Even though he did not like his nose, it looked masculine to me. I am especially attracted to the smell of his skin, I can just stick my nose in his neck all day. His kindness and understanding are what I am most attracted to. I feel he knows me very well and he protects my feelings. I am attracted to his knowledge, personality, and intelligence, and I enjoy listening to him talk. I am also attracted to his professional success in life. He might not look like a movie star, but I am attracted to him because he makes me feel safe, accepted, and loved."
I assumed the biology of love may be purely physical, but the roles of love and attraction in the human animal have changed by the evolution as what provides safety in modern life have changed.
