Cladistics (Greek: clados = branch) or phylogenetic systematics (Greek:
phylon = race and genetic = birth) is a branch of
biology that determines the
evolutionary relationships of living things based on derived similarities.
Full article >>>Cladistics is a type of systematics developed by Willi Hennig, who attempted to develop a more
objective method of
classifying
organisms.

Classification
Except for his last sentence where he used the word "evolved," Charles Darwin never mentioned "
evolution" in The
Origin of
Species. Instead, he used the phrase "descent with
modification.
Full article >>>Cladistics The practice of
classifying
organisms based on their phylogenetic relationships and
evolutionary history. Its goal is to delineate 'natural' groups which reflect 'true' relationships.

A
taxonomic approach that
classifies
organisms according to the
order in time at which branches arise along a
phylogenetic tree, without considering the degree of morphological divergence.
Full article >>>CladisticsIdeally, a system of
classification should reflect the genealogies of the
organisms. Darwin realized this when he wrote: "our
classifications will come, as far as they can be so made, genealogies".

characteristics so that the arrangement will reflect phylogenetic relationships.

cladistics-based schools of
taxonomy, the existence of
paraphyletic groups in a
classification is regarded as an error.
