BIO 182 EXAM 1 QUESTIONS AND
ANSWERS WITH SOLUTIONS 2024
Macroevolution - ANSWER Evolutionary change above the species level.
Ecological species concept - ANSWER identifies species in terms of their ecological niches, focusing on
unique adaptations to particular roles in a biological community
Postzygotic - ANSWER Barriers that prevent the hybrid zygote from becoming a fertile adult.
The theory of gradualism - ANSWER Profound geological changes took place through the cumulative
effect of slow but continuous processes identical to those currently operating
Prezyogotic - ANSWER Reproductive isolation
Artificial selection - ANSWER Breeding organisms with specific traits in order to produce offspring with
identical traits.
Microevolution - ANSWER Change in allele frequencies in a population over generations.
Biological species concept - ANSWER Definition of a species as a population or group of populations
whose members have the potential to interbreed in nature and produce viable, fertile offspring, but are
not able to produce viable, fertile offspring with members of other populations.
Population - ANSWER A local group of organisms belonging to the same species and capable of
interbreeding
According to evolutionary theory, the smallest entity that can evolve is
*evolve over time
Quantitative - ANSWER Characters (such as height) are those that vary along a continuum within a
population.
, Homologous - ANSWER Structures in different species that are similar because of common ancestry.
Gene flow - ANSWER Movement of alleles into or out of a population due to the migration of individuals
to or from the population
Stabilizing - ANSWER Natural selection that favors intermediate variants by acting against extreme
phenotypes
Disruptive Selection - ANSWER form of natural selection in which a single curve splits into two; occurs
when individuals at the upper and lower ends of a distribution curve have higher fitness than individuals
near the middle
Prokaryotic - ANSWER Single celled organism
Gradualism - ANSWER Occurrence over a period of time
Eukaryotic - ANSWER Multicellular organism
Speciation - ANSWER Genetic changes over time
Phylogeny - ANSWER Classification of organisms
Anaerobes - ANSWER Do not require oxygen to live
Creationism - ANSWER Religious viewpoint
Evolution - ANSWER Scientific viewpoint
Descent with modification
Aerobes - ANSWER Require oxygen to live
