//**classifacation:**// the process of organising organisms into groups based on predetermined criteria is called classiforcation. the classiforcation of living things is said to be a strong multilevel classiforcation. strong, because the scheme gives predictable results. multilevel because major groupings may be further subdivided into smaller, sub groups. the criterion we use to assign organisms to group is the closeness of the evolution relationship between members of the group. this is usually observed by looking at the number of features shared by organisms when we compare them. features that might be used when looking to groups organisms could include: 1. physical structures. (eg, anatomy of bones, teeth, organs etc) 2. biochemistry. (eg, protein simiarities) 3. manner of development. 4. behavioural characteristics. 5. similarities.
