Bio Anthro 2B Final Comprehensive
Questions (Frequently Tested) with
Verified Answers Graded A+
Micro Evolution - Answer: changes that are below the species level
Macro Evolution - Answer: changes that are above the species level
Taxonomy - Answer: classification of living things (hierarchical organization)
Binomial Nomenclature - Answer: Genus species (Homo sapiens)
How do we know if 2 creatures are the same species? - Answer: they reproduce effectively
(fertile and viable offspring)
Biological Species - Answer: group of regularly interbreeding population that is reproductively
isolated from other such groups
Speciation - Answer: one species splits into 2, involves reproductive isolating mechanism
Hierarchy of Living Things - Answer: Kingdom, Phylum, Class, Order, Family, Genus, Species
Extrinsic Reproductive Isolating Mechanism - Answer: factors producing geographic isolation
(ex: movement of tectonic plates)
Intrinsic Reproductive Isolating Mechanism - Answer: pre-zygotic: sperm cannot reach egg or
post-zygotic: improper development
, Fundamental Principle of Natural Selection - Answer: rate of evolutionary change is directly
proportional to degree of variability in a population (corollary)
Anagenesis - Answer: formation of species without branching out from lineage
Cladogenesis - Answer: speciation through a branching mechanism creating more than one
population
Phyletic Gradualism - Answer: emphasizes anagenesis, slow gradual change
Punctuated Equilibrium - Answer: emphasize cladogenesis, most change during speciation
events
Adaptive Radiation - Answer: rapid expansion and diversification of a group of organisms as
they adopt to newly available ecological space (cladogenic)
What causes adaptive radiation? - Answer: species occupy new location without competitors or
mutation changes adaptive potential
Generalized Species - Answer: does well in all environments (has greater adaptive potential)
Specialized Species - Answer: does well in one particular environment
Homology - Answer: similarities between organisms due to common ancestry (human arm and
bat wing)
*have different functions
