Example of a continuous trait are length of the limbs, or intelligence. To have tissue, the organism's body can work as one and can be organized. Ancestral groups that have similar characteristics are also called clades and are descended from an ultimate ancestral species. Cladistics is a method of hypothesizing relationships among organisms in other words, a method of reconstructing evolutionary trees. This method allows convergent characters to be grouped despite their having followed a separate evolutionary path. Cladistics is concerned with entire branchings by grouping all the common descendants into a clade as a related group and no others.this is a narrower definition of an Another ancestor broke off from the first species and led to the speciation of New World monkeys, followed by the ancestor of Old World monkeys.

Stuessy (1980) has given some conventional procedures, which are as follows: . How would you know if two chromosomes were homologous. Organisms are typically grouped by how closely related they are and thus, cladistics can be used to trace ancestry back to shared common ancestors and the evolution of various characteristics.

A trivial worked example will make this process much clearer. Cladistics is concerned with entire branchings by grouping all the common descendants into a clade as a related group and no others.this is a narrower definition of an older, less precise concept. cladistics is a way of grouping the related branches based on sharing derived characters within the group.
