Morphological species concept - Answer: a species is a distinct group of organisms
with a unique set of morphological characteristics (unique external form).
Biological species concept - Answer: defines a species as one or more
Population that can interbreed to produce fertile offspring but are
Reproductively isolated from other groups.
Reproductively isolated - Answer: When two species are prevented from interbreeding
Genetic heritage - Answer: a particular set of genes and alleles that is typical of the
species but different from that of all other species.
Who proposed evolution? - Answer: Charles Darwin
Natural selection - Answer: an evolutionary process that adapts a population to its
environment.
What does evolution not say - Answer: 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 - Answer: Similarity of life
• Shared characteristics
• Vestigial structures
• Development • Distribution of similar life
• Fossil record

,• Observation
• Microevolution
Evolutionary tree - Answer: illustrates the evolutionary history of groups of organisms.
Phylogenetics - Answer: goal is to construct evolutionary trees that illustrate the
patterns of
Species evolution.
Shared derived traits - Answer: evolutionary novelties shared by an ancestor and its
descendants but not seen in groups that are not direct descendants of that ancestor
Homologous traits - Answer: are features that organisms share
Because they have inherited them from a common ancestor.
Vestigial organs - Answer: organ that serves no useful function in an organism
Plate tectonics - Answer: The slow movement of the continents over time relative to one
another
Microevolution - Answer: is a small change in a species
• Not developing new species
Bottleneck effect - Answer: A change in allele frequency following a dramatic reduction
in the size of a population
Radioisotopes - Answer: unstable forms of
Elements that decay to more stable
Forms at a constant rate over time.

, Macroevolution - Answer: refers to large-scale changes in organisms, generally
occurring over millions of years.
Adaptive radiation - Answer: An evolutionary pattern in which many species evolve from
a single ancestral species
Speciation - Answer: the process in which one species splits to form
Two or more species that are reproductively isolated from each other.
4 mechanisms of evolution - Answer: The 4 mechanisms are: • Natural Selection
• Genetic Drift • Gene Flow
• Mutation
Gene pool - Answer: the sum of all the genetic information carried by all the individuals
in a
Population.
Gene flow - Answer: the movement of genes from one population to another.
Genetic drift - Answer: a random process that can cause the gene pool of a population
to change randomly from one generation to the next over time.
Mutations - Answer: are the ultimate source of all genetic variation and
Are the result of random changes in DNA sequences.
Artificial selection - Answer: is the process by which only individuals with certain
inherited characteristics are allowed to breed.
Natural selection - Answer: a nonrandom, directional process
That shifts the genetic characteristics of a population in one direction that leads to
adaptation over successive generations.
