questions with answers |\ |\




morphological species concept - CORRECT ANSWERS ✔✔a |\ |\ |\ |\ |\ |\ |\


species is a distinct group of organisms with a unique set of
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


morphological characteristics (unique external form).|\ |\ |\ |\




biological species concept - CORRECT 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 - CORRECT ANSWERS ✔✔When two |\ |\ |\ |\ |\ |\ |\


species are prevented from interbreeding
|\ |\ |\ |\




genetic heritage - CORRECT 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? - CORRECT ANSWERS ✔✔Charles
|\ |\ |\ |\ |\ |\ |\


Darwin


natural selection - CORRECT ANSWERS ✔✔an evolutionary
|\ |\ |\ |\ |\ |\ |\


process that adapts a population to its environment.
|\ |\ |\ |\ |\ |\ |\

,What does evolution not say - CORRECT 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 - CORRECT ANSWERS ✔✔Similarity of life
|\ |\ |\ |\ |\ |\ |\ |\




• Shared characteristics
|\ |\




• Vestigial structures
|\ |\




• Development • Distribution of similar life
|\ |\ |\ |\ |\ |\




• Fossil record
|\ |\




• Observation
|\




• Microevolution
|\




evolutionary tree - CORRECT ANSWERS ✔✔illustrates the |\ |\ |\ |\ |\ |\ |\


evolutionary history of groups of organisms. |\ |\ |\ |\ |\




phylogenetics - CORRECT ANSWERS ✔✔goal is to construct |\ |\ |\ |\ |\ |\ |\ |\


evolutionary trees that illustrate the patterns of |\ |\ |\ |\ |\ |\




species evolution. |\




shared derived traits - CORRECT 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 - CORRECT ANSWERS ✔✔are features that
|\ |\ |\ |\ |\ |\ |\ |\


organisms share |\




because they have inherited them from a common ancestor.
|\ |\ |\ |\ |\ |\ |\ |\




vestigial organs - CORRECT ANSWERS ✔✔organ that serves no
|\ |\ |\ |\ |\ |\ |\ |\ |\


useful function in an organism
|\ |\ |\ |\




plate tectonics - CORRECT ANSWERS ✔✔The slow movement of
|\ |\ |\ |\ |\ |\ |\ |\ |\


the continents over time relative to one another
|\ |\ |\ |\ |\ |\ |\




Microevolution - CORRECT ANSWERS ✔✔is a small change in a |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


species
• Not developing new species
|\ |\ |\ |\




bottleneck effect - CORRECT ANSWERS ✔✔A change in allele
|\ |\ |\ |\ |\ |\ |\ |\ |\


frequency following a dramatic reduction in the size of a
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


population


Radioisotopes - CORRECT ANSWERS ✔✔unstable forms of
|\ |\ |\ |\ |\ |\




elements that decay to more stable
|\ |\ |\ |\ |\




forms at a constant rate over time.
|\ |\ |\ |\ |\ |\




macroevolution - CORRECT ANSWERS ✔✔refers to large-scale |\ |\ |\ |\ |\ |\ |\


changes in organisms, generally occurring over millions of years.
|\ |\ |\ |\ |\ |\ |\ |\

, adaptive radiation - CORRECT ANSWERS ✔✔An evolutionary
|\ |\ |\ |\ |\ |\ |\


pattern in which many species evolve from a single ancestral
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


species


speciation - CORRECT 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 - CORRECT ANSWERS ✔✔The 4
|\ |\ |\ |\ |\ |\ |\ |\ |\


mechanisms are: • Natural Selection |\ |\ |\ |\




• Genetic Drift • Gene Flow
|\ |\ |\ |\ |\




• Mutation
|\




gene pool - CORRECT ANSWERS ✔✔the sum of all the genetic
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\


information carried by all the individuals in a|\ |\ |\ |\ |\ |\ |\




population.


gene flow - CORRECT ANSWERS ✔✔the movement of genes from
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


one population to another.
|\ |\ |\




genetic drift - CORRECT 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 - CORRECT ANSWERS ✔✔are the ultimate source of all
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\


genetic variation and |\ |\
