How can scientists use cladograms to place new species that have been discovered?

Scientists use cladograms to propose and ask questions about the evolutionary relationships between different species. By giving weigh to derived characters and recognizing ancestral characteristics, scientists can compare different phylogenies of the same groups of organisms.
