Taxonomy and Phylogeny
Carolus
Linnaeus
introduced a system of
classification
, or taxonomy, for grouping and naming similar
organisms
in hierarchical
categories
(taxa).
Using standardized scientific nomenclature avoids confusion that can arise from common
names
.
Charles
Darwin
proposed a theory of evolution to explain the adaptation of organisms to their environment in a process called natural
selection
.
Taxonomy should reflect phylogeny, the evolutionary history of organisms based on descent from a
common
ancestor.
The phylogeny of
plants
(Kingdom
Plantae
) reflects adaptation to terrestrial habitats.
Major Angiosperm families include:
Poaceae
(Gramineae)
Apiaceae
(Umbelliferae)
Asteraceae
(Compositae)
Fabaceae
(Leguminosae)
