Is there a catch to having muscles? Why did human female evolution decide muscles are a liability?
All I can find in a search engine is why humans evolved to be physically weaker than primates, because the metabolic cost of the brain was more important than muscles. In modern Western countries you no longer have to trade muscles for brain though.
For example in humans, I read online (I don't know from a credible source) that it takes females 15x longer to have as much muscular gains as men. From credible sources I found that muscle gains require androgenic receptors in the muscles. Why do muscles only respond to androgens and not estrogen, why did females evolve to not have strong muscles? Looking at other species, strong females are as brutal as males, like female bears, female hyenas, female lions, female chimpanzees etc.
One theory is that austerity culture deemed that more food be given to males and/or males had more appetite due to testosterone. This might explain this because modern females both have less brain volume and less muscle strength than modern males, although both modern males and modern females have much less brain volume and probably muscle strength also than primitive man and primitive woman, who had almost equal brain volume. If the driver of muscle decrease was metabolic resource management then that might also explain cognitive volume decrease. But I'm not sure how it could explain a discrepancy of 15x.
