Final answer:
The statement that culture is shared by all members of the order Primates is false, as not all primates exhibit the complex social structures and cultural behaviors seen in Hominidae, such as humans and certain great apes.
Step-by-step explanation:
The statement 'Culture is shared by all members of the order Primates a)True b)False' is false. Culture, in the context of complex social structures and the transmission of learned behaviors, is not universally exhibited by all primates. While all organisms in the Hominidae, such as humans, share some forms of communication and can create simple cultures, this is not as evident in other members of the primate order. Within primates, there is a spectrum of social complexities and cultural behaviors, and the ability to develop and sustain a culture similar to humans is more predominant in some species of the order, such as certain great apes, but not for all primates.
For instance, the prosimians, which include creatures like lemurs and tarsiers, tend to be nocturnal and have smaller brains compared to anthropoids (monkeys, apes, and humans), and show less evidence of complex culture. It is important to note that primates have diverse adaptations and behaviors, thus not all primate species exhibit cultural characteristics to the extent seen in humans or some other higher primates.
