consists of interbreeding populations of organisms that can produce healthy fertile offspring.
What is a species ?
100
change over time
What is evolution ?
100
Similar structures that are inherited from a common ancestor.
What are homologous structures ?
100
the evolution of one or more species from a single ancestor species
What is speciation ?
100
a common group of genes shared by a population that interbreeds.
What is a gene pool ?
200
is an inherited trait that increases a populations chances of survival.
What is an adaptation?
200
increases the chance that a species will adapt to survive future changes in the environment
What is diversity ?
200
When isolated populations of a species evolve independently.
What is Allopatric Speciation ?
200
is the evolution of many diversely adapted species fro one common ancestor.
What is adaptive radiation ?
200
the number of times one allele occurs in a gene pool compared with the number of times the other allele occurs
What is allele frequency ?
300
is defined as the differences between individual members of a population.
What is variation?
300
occurs at a slow but constant rate.
Over a short period of time it is hard to notice
What is Gradualism ?
300
Reduced (smaller) forms of functional (useful) structures in other organisms
What is vestigial structures ?
300
Species that adapt to one another. They depend on each other for survival.
What is coevolution ?
300
The most rare blood type. Thus, has the lowest frequency.
What is type AB ?
400
is any preserved evidence of an organism.
What is a fossil ?
400
a theory that consists of four main points:
Individuals in a population show differences or variation
Variation is inherited or passed down from parents to offspring
What is natural selection ?
400
this useless organ in the human body is an example of a vestigial structure.
What is an appendix ?
400
When different species with different ancestors develop similar, or analogous adaptations in response to similar environments.
What is convergent evolution ?
400
is the random change in allele frequencies in a population due to chance events.
What is genetic drift ?
500
includes where organisms live, what and how they eat, how they raise their offspring, etc...
What is a niche ?
500
populations stay genetically stable for long periods of time, interrupted by brief periods of rapid change.
What is punctuated equilibrium ?
500
is a national symbol of New Zealand, and the association is so strong that the term is used all over the world for New Zealanders.
What is a kiwi ?
500
this species found in California has neurotoxin which was once used by natives to stun fish.
What is California buckeye ?
500
selection that does not favor the most common variation within a population.
