The second step of classification is using homologous traits to determine the relationships between organisms. Based on the traits you identified in Exercise 3, it should now be possible to group some of the objects together. Objects that share a derived trait are related to one another, and they should be grouped together. Objects that share multiple shared derived traits are closely related, and they should be subgroups within larger related groups.Describe the groups in which you would place these objects, starting with groups with the largest number of objects and ending with the group with the smallest number of objects.

Evolutionary lineages

An evolutionary lineage is a series of populations of organisms that descend from a common ancestor. Each species in the lineage is the direct consequence of evolutionary change from a common ancestor. A phylogenetic tree is generally used to display lineages visually. Lineages are components of the phylogenetic tree of life. Molecular systematics procedures are widely used to predict lineages.
