Solution
The reason male and female gibbons are similar in size and lack sexual dimorphism is due to decreased competition for mates in a monogamous social structure. Gibbons are known for their monogamous mating system, which is quite rare among primates. In species where males and females are similar in size, it often indicates that there is less competition among males for access to females. This is because in a monogamous system, each male has only one mate, so there is no need for males to be larger or more aggressive to compete for multiple mates. This results in both sexes evolving to be similar in size.
