Evolution #1
Change in a population of a species over time
What is Evolution
Same structures but different function
What are Homologous structures
The study of fossils
What is Paleontology
Type of evolution in which 1 species splits into 2 new species
What is divergent evolution
Type of isolation exhibited by the Western spotted skunk
What is Temperal Isolation
Another name for natural selection
What is survival of the fittest
Evolution due to chance
What is genetic drift
increase in the frequency of extreme types in a pop.
What is Disruptive selection
Microevolution + time = ?
What is Macroevolution
Bringing in new alleles from another population
What is gene flow
The process where new species form due to a geographic barrier that isolates populations, preventing gene flow, such as the the finches on the Galapagos Island observed by Darwin.
What is Allopatric Speciation
Male Donkey + Female Horse = Mule
What is Hybrid Sterility
small population, non-random mating, mutations, gene flow, Natural selection
What is the five fingers (microevolution)
Type of isolation where different mating seasons may create a barrier
What is temporal isolation
All of the available genes within a population
What is gene pool
Type of evolution that leads to unrelated species developing similar traits
What is Convergent Evolution
Brown bears and polar bears descended from a common bear
What is Divergent Evolution or Adaptive radiation
The proportion of homozygous recessives in a population, can be determined by using?
What is the Hardy - Weinberg equation
Two or more species evolve together
What is coevolution
