'''Phylogeny''' describes the relationships between groups of animals as understood by ancestor/descendant history, so that groups are linked together on the basis of the recency of common ancestry. This is assessed primarily by the recognition of shared derived characters. The pattern of evolutionary relationships within and between groups can be depicted in the form of a branching diagram called [[cladogram]]s, which are like genealogies of [[specie]]s.

'''Phylogeny''' is a pseudo-scientific concept that describes the alleged relationships between groups of animals as understood by ancestor/descendant history, so that groups are linked together on the basis of the recency of their supposed common ancestry. According to some evolutionists this is assessed primarily by the recognition of shared derived characters. The pattern of evolutionary relationships within and between groups can be depicted in the form of a branching diagram called [[cladogram]]s, which are like genealogies of [[specie]]s.

Not only is phylogeny important for understanding paleontology, but paleontology in turn contributes to phylogeny. Many groups of organisms are now extinct, and without their fossils we would not have as clear a picture of how modern life is interrelated.

Evolutionists often argue that not only is phylogeny important for understanding paleontology, but paleontology in turn allegedly contributes to phylogeny. Many groups of organisms are now extinct, and without their fossils we would not have as clear a picture of how modern life is interrelated. Despite this, Darwinists often fill in the gaps and extrapolate results to fit the preconceived picture they have already agreed upon. 

[[Evolution|Evolutionist]] [[Ernst Haeckel]] is well known for his claim that "[[ontogeny]] recapitulates phylogeny," meaning that organisms pass through stages in development that mirror their evolutionary history. Though some of the drawings he produced as evidence of this claim were later found to be fraudulent, evolutionary biologists maintain that other evidence supports this conclusion, albeit not as strongly as Haeckel suspected.
