“By definition, a clade is a group composed of a single ancestor and all its descendants.”
“In cladistics, the clade is a hypothetical construct based on experimental data.”
“Understanding Evolution: A clade is a grouping that includes a common ancestor and all the descendents (living and extinct) of that ancestor … Clades are nested within one another — they form a nested hierarchy.”
“A clade is an ancestor species and all of its descendants”
“If we look at the definition of clade - A clade is a group, consisting of a single organism and all of its descendants. - my premise is correct as aves are a descendent of reptiles - that is if we go by the cladogram …”

mollusque One definition is based on the method of analysis that produces the branching diagram (tree), the other is based on the way the tree is converted into a classification. The cladistic method identifies characters that are shared by groups (features inherited from a common ancestor), but some of those characters might be lost in some members of the group. The cladistic method also says that given a particular tree topology, the only groups that should be recognized are those that can be removed from the tree with a single cut (which gives an ancestor and all its descendants, i.e., a monophyletic group).

qroqqa The problem is that two 'definitions' found on the Internet are mutually inconsistent. That's got nothing to do with what a clade is. Clades are defined by descent; there's no actual need for any two members of a clade to share any particular inheritance. A clade is a species together with all its descendants. Nov 21, 2011
hernesheir Perhaps the terms "derived from" and "inherited from" are problematical. The former, "derived from" suggests the bugbear (to some) evolution. The latter, "inherited from" seems less problematical because most people accept the principle(s) of inheritance. I don't see much contradiction. Nov 20, 2011
Mats Envall The problem with the concept "clade" is thqt groups of "animals or other organisms derived from a common ancestor species" (the first definition above) are not consistent with groups of"animals that share features inherited from a common ancestor" (the third definition above). The problem is thus that the concept "clade" is internally inconsistent, that is, contradictory. Such things simply can't be found (non-contradictory). Nov 19, 2011
