Phylogenetic Tree - 🧠 ANSWER ✔✔A branching diagram that represents a
hypothesis about the evolutionary history of a group of organisms
Taxon - 🧠 ANSWER ✔✔A named taxonomic unit at any given level of
classification
What is the difference between a phylogenetic tree and a classification? - 🧠
ANSWER ✔✔•A phylogenetic tree is a representation of an evolutionary history
hypothesis for a group of organisms as a result of cladistic analysis,
•While classification uses information from cladistic analyses and traditional
phylogenetic analyses to group animals into a group of higher taxa (Kingdom,
Phylum, Class, Order, Family, Genus)
What is the difference between a clade and a group of animals at a given
taxonomic rank? - 🧠 ANSWER ✔✔•A clade is a monophyletic group therefor
containing a common ancestor and all of it descendants,
•While animals of a taxonomic rank are grouped by their classification (Kingdom,
Phylum, Class, Order, Family, Genus)
What is the correct order of nesting of taxonomic levels within a classification? - 🧠
ANSWER ✔✔•Kingdom, Phylum, Class, Order, Family, Genus
