20 Questions
According to the Biological Species Concept, a species is defined as a group of populations that
have the potential to interbreed and produce viable offspring
What is the main criteria used by biologists to group organisms when applying the Biological Species Concept?
Genetic similarity
Gene flow between populations of a species
increases genetic diversity
Which statement best describes the concept of reproductive isolation?
It prevents successful interbreeding between different species
Temporal isolation is a type of reproductive barrier that occurs when
organisms are active during different times of the day
Behavioral isolation is a type of reproductive barrier that occurs when
organisms have different mating behaviors
Mechanical isolation is a type of reproductive barrier that occurs when
organisms have incompatible genitalia
Which of the following is NOT a prezygotic reproductive barrier?
Geographic isolation
What is the main difference between prezygotic and postzygotic reproductive barriers?
Prezygotic barriers prevent the formation of a zygote, while postzygotic barriers prevent the survival or reproduction of hybrid offspring
Hybrid inviability and hybrid infertility are examples of
postzygotic barriers
Which scientist discovered plants and animals in the Galápagos Islands that were found nowhere else on Earth?
Charles Darwin
What is speciation?
The process by which one species splits into two or more species
What do species that result from speciation share?
Some characteristics inherited from their common ancestor
What is microevolution?
Changes in allele frequency in a population over time
What is macroevolution?
Broad patterns of evolutionary change above the species level
What does macroevolution include?
Both changes in allele frequency and the origin of new groups of organisms
What is the main focus of microevolution?
Changes in allele frequency in a population over time
What is the main focus of macroevolution?
The origin of new groups of organisms
What does speciation form a conceptual bridge between?
Microevolution and macroevolution
What is the "Mystery of Mysteries" mentioned in the text?
The conceptual bridge between microevolution and macroevolution
Test your knowledge on the process of speciation and the unique plants and animals found in the Galápagos Islands. Learn about Darwin's discoveries and how one species can split into multiple species. Explore the mystery and beauty of these extraordinary creatures in this quiz.
