BIOLOGY 1400 FINAL EXAM - LITTLE
UCA COMPLETE QUESTIONS WITH
100% VERIFIED ANSWERS
\.morphological species concept - ANSWERS-a species is a distinct group of
organisms with a unique set of morphological characteristics (unique external
form).
\.biological species concept - ANSWERS-defines a species as one or more
population that can interbreed to produce fertile offspring but are
reproductively isolated from other groups.
\.reproductively isolated - ANSWERS-When two species are prevented from
interbreeding
\.genetic heritage - ANSWERS-a particular set of genes and alleles that is typical of
the species but different from that of all other species.
\.Who proposed evolution? - ANSWERS-Charles Darwin
\.natural selection - ANSWERS-an evolutionary process that adapts a population
to its environment.
,\.What does evolution not say - ANSWERS-Evolution in NO WAY says we evolved
from monkeys
• Evolution DOES NOT disprove intelligent design
• Evolution DOES NOT have a direction
• Nothing is more or less evolved
• Evolution IS NOT a choice
\.Evidence for evolution - ANSWERS-Similarity of life
• Shared characteristics
• Vestigial structures
• Development • Distribution of similar life
• Fossil record
• Observation
• Microevolution
\.evolutionary tree - ANSWERS-illustrates the evolutionary history of groups of
organisms.
\.phylogenetics - ANSWERS-goal is to construct evolutionary trees that illustrate
the patterns of
species evolution.
,\.shared derived traits - ANSWERS-evolutionary novelties shared by an ancestor
and its descendants but not seen in groups that are not direct descendants of that
ancestor
\.homologous traits - ANSWERS-are features that organisms share
because they have inherited them from a common ancestor.
\.vestigial organs - ANSWERS-organ that serves no useful function in an organism
\.plate tectonics - ANSWERS-The slow movement of the continents over time
relative to one another
\.Microevolution - ANSWERS-is a small change in a species
• Not developing new species
\.bottleneck effect - ANSWERS-A change in allele frequency following a dramatic
reduction in the size of a population
\.Radioisotopes - ANSWERS-unstable forms of
elements that decay to more stable
forms at a constant rate over time.
\.macroevolution - ANSWERS-refers to large-scale changes in organisms, generally
occurring over millions of years.
, \.adaptive radiation - ANSWERS-An evolutionary pattern in which many species
evolve from a single ancestral species
\.speciation - ANSWERS-the process in which one species splits to form
two or more species that are reproductively isolated from each other.
\.4 mechanisms of evolution - ANSWERS-The 4 mechanisms are: • Natural
Selection
• Genetic Drift • Gene Flow
• Mutation
\.gene pool - ANSWERS-the sum of all the genetic information carried by all the
individuals in a
population.
\.gene flow - ANSWERS-the movement of genes from one population to another.
\.genetic drift - ANSWERS-a random process that can cause the gene pool of a
population to change randomly from one generation to the next over time.
\.mutations - ANSWERS-are the ultimate source of all genetic variation and
are the result of random changes in DNA sequences.
\.artificial selection - ANSWERS-is the process by which only individuals with
certain inherited characteristics are allowed to breed.
