organize based on common ancestors. This highlights the evolutionary development characteristics. From this view we can locate similar characteristics or homoplasy among multiple species who do not share immediate common ancestors.

Homoplasy also called *convergent evolution * is the observed phenomenon that different species have developed similar characteristics that they did not inherit from a common ancestor. A common example is that both birds and bats have wings for flight that they did not inherit from their common ancestor (Synapsids).
Phylogenic trees identify common ancestors based on both physical traits (phenotype) and genetic traits (genotype).
