(Auld)
What is meant by the term "emergent property"? - ✔️✔️A property which a collection or
complex system has, but which the individual members do not have.
What is a hypothesis? - ✔️✔️A rational accounting for a set of observations, guided by
inductive reasoning.
What is a theory? - ✔️✔️A hypothesis that has been repeatedly tested and not
rejected.
What is qualitative data? - ✔️✔️Information about qualities; information that cannot
actually be measured.
What is quantitative data? - ✔️✔️Information about quantities; information that can be
measured with and written down with numbers.
Why is evolution a unifying theory in biology? - ✔️✔️Evolution helps scientists find the
connections between all of the different species on earth.
What are the three domains of life? - ✔️✔️Archaea, Bacteria, and Eukarya
What are the kingdoms in the Eukarya domain? - ✔️✔️Protista, Fungi, Animalia, and
Plantae
What is meant by the term "descent with modification"? - ✔️✔️Homology
What is homology? - ✔️✔️Similarity resulting from common ancestors.
What are homologous structures? - ✔️✔️Structures with underlying similarities but
different functionality.
What is the mechanism behind adaptation? - ✔️✔️Natural selection
What is a phylogeny? - ✔️✔️A pictorial hypothesis about evolutionary history; they may
show species or other taxa
What is a branch point on a phylogeny? - ✔️✔️Where lineages diverge
What is a polytomy on a phylogeny? - ✔️✔️An unresolved pattern of divergence
