Question

Mammals are divided into several orders. Which order includes the most advanced mammals?

• A. Primates
• B. Sirenia
• C. Pholidota
• D. Cetacea

Answer 1

The correct option is A Primates

A primate is a mammalian animal constituting the taxonomic order Primates. They are the most advanced mammals. Primates arose 55-85 million years ago from terrestrial ancestors (Primatomorpha), who adapted to living in the trees of tropical forests: many primate characteristics represent adaptations to life in this challenging environment, including large brains, visual acuity, color vision, altered shoulder girdle, and dexterous hands. Primates range in size from Madame Berthe's mouse lemur, which weighs 30 g (1 oz), to the eastern gorilla, weighing over 200 kg (440 lb). There are 190 - 448 species of living primates, depending on which classification is utilized. New primate species continue to be discovered: over 25 species were described in the first decade of the 2000's, and eleven since 2010.

So the correct option is 'primates'.
