Primates: big brain, strong reliance on vision, forward facing eyes (3d vision, dexterous hands (opposable thumbs) Procimian primates: ealriest, big eyes, pre monkeys, small creatures. Old and new world monkeys: based on parts of the world. Great apes and lesser apes: apes are our closest relatives, they are interesting to study.

Number of genes: determines the complexity of the animal, shared genes 37% of our genes we share with bacteria, we inherit a lot from other organisms.
