similar characteristics in related organisms
similar coincidences from convergent evolution
clade with all decendents of an ancestor
clade with some decendents of an ancestor
includes taxa with different ancestors
shared ancestral characteristics
from ancestor of taxon
shared derived characteristics
distinct to clade
simplest explanation (=most reliable)
homologous genes from speciatoin
found in multiple copies in the same genome (repetitions)
What is the difference between Phylogeny and Systematics?
phylogeny is the evolutionary history of a species, while systematics is a method in which phylogeny may be categorized.
phylogenies show evolutionary relationships through...
phylogenic trees show the order of...
the more complex similarities between two organisms...
the greater chance they are related
true/false, molecular homoplasies are possible
the greater the parsimony...
the simpler and more reliable it is
true/false molecular clocks are constant
false--they only show order, but do not assign a specific time period
