Final answer:
Anthropoids (Haplorrhine) and Prosimians (Strepsirhini) are two groups of primates in the order Primates. They differ in their activity patterns, size, brain size, and vitamin C production.
Step-by-step explanation:
Anthropoids (Haplorrhine) and Prosimians (Strepsirhini) are two groups of primates that belong to the order Primates. Anthropoids include monkeys, apes, and humans, while prosimians include lemurs, bush babies, and lorises. The main differences between anthropoids and prosimians are their activity patterns, size, brain size, and vitamin C production. Anthropoids are primarily diurnal and rely more on their vision, while prosimians are mainly nocturnal and have a larger olfactory center in the brain. Prosimians are generally smaller in size with smaller brains compared to anthropoids. Additionally, prosimians have the enzymes to produce vitamin C, while anthropoids need to obtain it from their diet.
