Document Summary
The scieniic discipline of organizing living things into groups which relect their phylogeneic relaionships, is called: taxonomy, taphonomy, cladisics, systemaics, phylogram. Branching patern showing relatedness relaionships between species (or higher taxa) based on their shared common ancestors. A & b are most closely related because they share a common ancestor (call the ancestor. E ) that c and d do not share: a & b is a taxon. A + b + c are more closely related to each other than to d because they share a common ancestor ( f ) that d does not share. A + b + e = clade. A + b + e + f + c = clade: clades always have the common ancestor. A & b share a more recent common ancestor than a + b + c. Many traits are used to create a phylogeny; less well understood traits can be mapped on a phylogeny to understand important evoluionary events.
