CladogramsDerived characteristics – characteristics that evolved in an ancestor that is common to all species on one branch of a fork in the tree but not common to the other branchExample 1 - Evolution of vertebrates, which are all animals with a backboneSpeciesBony SkeletonPaired AppendagesEnlarged CraniumMammary GlandsSmall CaninesTotalLamprey000000Shark010001Frog110002Dog110103Chimp111104Human111115Practice:1)Three new species of butterflies have been discovered. All of them have broad wings. Two of the butterflies have yellow wings, while the other species has blue wings. One of the yellow -winged butterflies has white spots on its body, while the other has red stripes. Draw a cladogram indicating the probable evolutionary origin of the butterflies.SpeciesBlue wingsYellow wingsRed stripesWhite spotsTotalButterfly-110001Butterfly-201012Butterfly-301102
2)Some species of dragonflies have been discovered. Two of the new species have red eyes, while two other species have blue eyes.
