If you believe that some deity snaped his fingers and man was created, nothing I am about to say will make any sense to you.
Human beings evolved as social animals, and we have been in existence 300,000 thousand of years. We have only had about 6,000 years of recorded history when civilization formed. So 98% of human history is lost, and in that first 249,000 years human beings had to literally fight monsters, and other human tribes, with our only advantage being our advanced brains, ability to adapt, with the willingness and ability to work as collective groups. This is how we survived.
Since we are a sexual dimorphic species, with males being physically stronger, being a distinct advantage in an uncivilized environment where things like sabretooth tigers had to be fought off... in fact archeological evidence indicates that the beast that killed most early humans is an animal that still exists... leopards. Leopards are extremely suited for hunting primates, they can climb trees, swim, and pretty much get to any human trying to get away. But big cats, lions in Africa, tigers in Asia, cougars in the Americas, were early man's biggest threat. In fact, the sound of a tiger roaring today still triggers an adrenaline rush in people, as a primal instinct, even with people who have never heard or seen a tiger before.
The only defense early man had in this environment was the ability to communicate complex ideas, work together as a team, function in a wide variety of environments, the ability to migrate long distances to escape things like droughts and changing weather conditions, and the intelligence to create and use tactics and weapons to confront these threats.
What determined the success of a 'tribe' was the willingness and ability of males to work together as a team, which included the willingness to sacrifice for the good of the group. Males are genetically driven to cooperate in an effort to shape the environment they are in. Females, because we are genetically formed to have children and take care of them in early life, they are not genetically suited for confronting a harsh environment. Early human communities were successful if females in the group were able to ADAPT to the environment they are in, and integrate with other females in the group for mutual assistance.
For a male in early human history to be successful, he had to be strong, and a team player putting the needs of the group ahead of their own. We still see this today with bullying with male children. The boys that get bullied are the ones that are weak, and or not willing to comport to the group culture. It is lizard brain sh1t, a boy that is bullied will continue to be bullied until they fight back or modify their behavior to comport to the group. Girls that get bullied by other girls are those that do not comport to the female friend group... humans are particularly susceptible to peer pressure. Loners and introverts did not survive in early human history.
Males survived by being strong and clever enough to operate as a collective group: females survived by building relationships with other females while attaching herself to a strong male.... her advantage was not strength, it was the ability to emotionally manipulate the group. Again, this is all lizard brain sh1t, that runs in the background like an operating system on a computer. Even though these traits are no longer important in civilized culture, it is still genetically encoded.
Now that the early human sociology lesson is done... the OP is correct to a point. the lizard brain in the modern female is automatically attracted to males that exhibit leadership traits and/or the social acuity to successfully function effectively in the group, strength, and the willingness to sacrifice. A male that is strong but doesn't have social traits (which is willingness to sacrifice for the needs of the group) is not going to have long term success with women. So what the OP calls 'simping' (i.e. willingness to sacrifice individual wants for the needs of a group) is part of the genetic male make-up. First and foremost the early female wanted the leader, but not everyone can get the leader, but getting on the good side of the females attached to leaders, was a good survival tactic... so those females that did not get with the leader would be attracted to the males that had good relationships with the leader... having a good relationship with the leader has a direct correlation to the willingness of the subordinate male to sacrifice for the leader and the group. Females attached to subordinate males had to ALWAYS have a back-up plan because this was a dangerous environment and anytime a group of males went out to hunt, there was a good chance her male would not return.
However, while this trait was an important part of early human development, in modern civilization what the OP calls 'simping' is a sign of weakness, because in modern culture, simps just get used because there is no longer a personal connection with the social group... so the modern male human has to walk that fine line, they have to demonstrate some 'simp' characteristics. You can do this by giving, only when you get reciprocity. Someone that gives and gives and gives and expects nothing in return is just wearing a sign on his back that says "Thank you sir, can I have another!"
