ELI5: Why, in humans, are males generally larger than females when it is the opposite in most other species?
gpt
Humans, like most non-human primates, have sexual dimorphism in which the males tend to be larger than the females. Some primates (like chimpanzees and bonobos) see the males almost twice the size of females. Sexual dimorphism appears in body size, muscle mass, canine teeth, craniofacial structure, and even sometimes deepening voices. 

There are very few primate species that have reverse dimorphism (females larger than males), so it appears to be "normal" that humans display the same dimorphism that other primates "typically" have.
