What is an evolutionary tree? - Understanding Evolution

Weblineage. n. 1. a. Direct descent from a particular ancestor; ancestry. b. Derivation. 2. The descendants of a common ancestor considered to be the founder of the line. Lineages are typically visualized as subsets of a phylogenetic tree. A lineage is a single line of descent or linear chain within the tree, while a clade is a (usually branched) monophyletic group, containing a single ancestor and all its descendants. Phylogenetic trees are typically created from DNA, RNA or protein sequence data. Apart from this, morphological differences and similarities have been, and still are used to create phylogenetic trees. Sequences from different individuals … contact jake auchincloss
