Taxonomy And Phylogeny Flashcards
8 areas if classification
Domain Kingdom Phylum Class Order Family Genus Species
Classification
The grouping of objects based on physical similarities, called taxonomy in biology, based in morphology, Linnaeus and Whittaker gave us this system
3 domains
Archaea
Bacteria
Eukarya
Domain archaea
Ancient prokaryotes that live in extreme environments
Domain bacteria
Modern prokaryotes that live in our bodies
Domain eukarya
All eukaryotic cells including plants, animals, fungi, and Protista
2 “dead languages” that taxonomists use for naming each species
Ancient Greek
Latin
Reasons why we use “dead language”
So language doesn’t evolve
So names don’t show preference to culture, region, or dialect
Order of how to name a species
Geneus name (capitalized), species name(not capitalized); both words are italicized if typed or underlined if written
_________ tree is based on a _________ analysis and called a ___________
Phylogenic ; cladistic ; cladogram
Synapomorphies
Derived characteristics
Clade
A group of organisms and their common ancestor
Out group on a cladogram
Least related and furthest to the left
Most derived on a cladogram
Most related organism and furthest to the right
