Lesson Summary: A name by any other tree

Lesson summary for... A name by any other tree Author/Source: Evolution: Education and Outreach

Overview:	Phylogenetics has affected almost every area of biology - even the most basic one: how we classify organisms. Find out how phylogenetic classification works and what its advantages are. This article appears at SpringerLink.
Concepts:	This lesson covers the following concepts: Through billions of years of evolution, life forms have continued to diversify in a branching pattern, from single-celled ancestors to the diversity of life on Earth today. Present-day species evolved from earlier species; the relatedness of organisms is the result of common ancestry. Classification is based on evolutionary relationships. Evolutionary trees (e.g., phylogenies or cladograms) portray hypotheses about evolutionary relationships.
