Questions (Frequently Tested) with
Verified Answers Graded A+
Macro-Evolution - Answer: Major evolutionary change
Micro-Evolution - Answer: evolutionary change within a species over a short period of time
Speciation - Answer: The evolutional process by which populations evolve to become distinct
species
Reproductive Isolating Mechanisms- name the 4 types - Answer: Intrinsic, Extrinsic, Pre-Zygotic,
Post-Zygotic
Pre-Zygotic - Answer: Anything that prevents mating and fertilization
Post-Zygotic - Answer: A mechanism that reduces the viability or reproduce capacity of hybrid
off spring; includes Intrinsic, Extrinsic
Natural Selection and Population Variability - Answer: There must be variability for natural
selection to occur
Anagenesis - Answer: Species formation without branching of the evolutionary line of descent
Cladogenesis - Answer: The formation of a new group of organisms by evolutionary divergence
from an ancestral form
, Phyletic Gradualism - Answer: Rates of speciation are slow or "gradual"
Punctuated Equilibrium - Answer: Speciation occurring in spurts of relatively rapid speed
Adaptive Radiation - Answer: The diversification of a group of organisms into forms filling
different ecological niches
Generalized Species - Answer: Species that can survive off of many different things; if
something changes in ecosystem these types are more likely to survive
Specialized Species - Answer: Species that are very good at once particular thing; ie anteaters
and eating ants. As long as there are ants then they're good but if ants go extinct then they too
will go extinct
Evolutionary Homology - Answer: A similarity in structures due to ancestral history
Evolutionary Analogy (Homoplasy) - Answer: Giving rise to structures that preform the same
task but not because of ancestral history, two types; parallel and convergence
Derived Traits - Answer: Traits inherited from ancestors
Shared Derived Traits - Answer: Two different species that have a recent common ancestor will
share many derived traits
Post-Orbital Bar - Answer: The bone that goes around the eye
Post orbitals Partition (Septum) - Answer: The closure behind the eyes of certain primates
