Document Summary
Each organisms is related in some way to all other organisms, creating a vast tree of life. Family genealogy refers to related individuals within a family vs. cladogram which looks at taxa. Comprises 3 main assumptions about the relationships among the organisms. There are changes in characteristics, which are the genetic or physical features of the organisms, within lineages over time. All organisms are descended from a common ancestor. When a lineage splits, it divides into exactly two groups. Issue because there are cases where one species evolved rapidly, in. Data used to create cladistic trees terms of geologic time frames, into multiple species. All data should be used to determine phylogenetic relationships (fossils often represented only by a few scraps of bones and teeth) Experimental research has shown that conflicting cladograms can result from the use of differing datasets on the same species. Biological evolution is trick because it can produce homoplastic character.
