In a phylogenetic tree what is a clade
WebA phylogenetic tree or evolutionary tree is a diagrammatic representation of the evolutionary relationships among various taxa (Figure 9.1 A–D ).

The green box (central) may represent an evolutionary grade ( paraphyletic ), a group united by conservative anatomical and physiological traits rather than phylogeny. The flanking red and blue boxes are clades (i.e., complete monophyletic subtrees).
WebFigure 2. All the organisms within a clade stem from a single point on the tree. A clade may contain multiple groups, as in the case of animals, fungi and plants, or a single group, as in the case of flagellates. Groups that diverge at a different branch point, or that do not include all groups in a single branch point, are not considered clades. WebPhylogenetic trees are generally based on many more characters and often involve more lineages. For example, biologists reconstructing relationships between 499 lineages of seed plants began with more than 1400 molecular characters! What is parsimony? The tree-building process explained above is based on the principle of parsimony.
WebA clade is a group of organisms defined by their having a common biological ancestor, irrespective of how closely they may or may not resemble one another. To be a clade, the group must contain the ancestor and all of its descendants — and no one else — a condition known as monophyly ("mono-" meaning "one" and "phyl-" meaning race, tribe, or kind).
