PPT-Chapter 4 Phylogeny and evolutionary history

Read Chapter 4 Phylogeny All living organisms are related to each other having descended from common ancestors Understanding the evolutionary relationships between groups enables us to reconstruct the tree of life and gain insight into history of evolutionary change. Phylogenies. The process of evolution produces a pattern of relationships between species. . As . lineages evolve and split and modifications are inherited, their evolutionary paths diverge. .

Phylogeny is the study of relationships among different groups of organisms and their evolutionary development. Phylogeny attempts to trace the evolutionary history of all life on the planet. It is based on the phylogenetic hypothesis that all living organisms share a common ancestry. The relationships among organisms are depicted in what is known as a phylogenetic tree. Relationships are determined by shared characteristics, as indicated through the comparison of genetic and anatomical similarities.. Nasser Ben Qasem . 503-Biology . WIU .
