What is a homoplasy?
Give this one a try later!
Similar trait due to convergent evolution (should NOT be used in
phylogenies b/c will lead to incorrect conclusions)
What is homology?
Give this one a try later!
, Similar trait due to common ancestry (should be used in
phylogenies).
What is congruent data?
Give this one a try later!
Indicates the same evolutionary relationships, more congruent data means
a higher likelihood of a bifurcating tree (see Phylogeny Slides of example)
What is a synapomorphy?
Give this one a try later!
A shared, derived (or new) trait (found in MRCA and all descendants)
NOTE: If a trait is defined as a synapomorphy, all group members will
possess the trait
What does a node represent?
