The scientific study of the diversity of living things and of the relationships among them -
answer What is the field of systematics?
The evolutionary history of a species or group of related species - answer What is a
phylogeny?
Links the most common ancestor - answer What are nodes?
Individual organisms, to species, or to sets of species - answer What are tips?
The path of transmission of genetic information from one generation to the next -
answer What are branches?
The tips of the tree represent groups of organisms - answer What are taxas?
Shared characteristics - answer What are synapomorphies?
The phylogeny tree includes ancestors and ALL descendants - answer What makes a
group monophyletic?
The phylongeny tree includes ancestor and SOME descendants - answerWhat makes a
group paraphyletic?
Mouse, opoussm, platypus, turtle, iguna, alligtaor, chicken - answerWhat taxa have an
amniotic egg?
Mouse - answerIs a platypus more closely related to a turtle or to a mouse?
Oldest - answerAre fish the oldest or the most recent diversification?
Reptilia clade paraphyletic - answerWhat would you call a clade that includes all
reptiles, but excludes birds?
Mouse, opossum, platypus - answerLabel the tetrapod clade
Number 3; It states that C is closer related to A rather than B being more closley related
