B. There are two means by which scientists classify organisms, classic taxonomy and cladistics. The primates are divided into two major taxonomic groups: strepsirrhines, which retain primitive characteristics, such as the lemurs of Madagascar and the bushbabies of Africa, and the more derived haplorrhines, that is, the tarsier, monkeys, and apes. Tool use with some modification (e.g. They have a different technique to fly. As many years went by, the environment changed such that the aquatic food sources were much more plentiful Female mallard ducks (as well as several other species in the genus Anas, such as the American and Pacific black ducks, spot-billed duck, northern pintail and common teal) make the classic "quack" sound while males make a similar but raspier sound that is sometimes written as "breeeeze",[29][self-published source?] see Figure 2.9!)
