Speciation - Yr 10

What is speciation?

• The process by which new species arise through evolution

• The extinction of a species

• The migration of species to new habitats

• The domestication of wild animals

Which of the following is NOT a type of speciation mentioned in the presentation?

• Allopatric speciation

• Sympatric speciation

• Parapatric speciation

• Geographic speciation

Darwin's finches are an example of which type of speciation?

• Allopatric speciation

• Sympatric speciation

• Convergent evolution

• Coevolution

What is the main difference between allopatric and sympatric speciation?

• Allopatric involves geographic barriers, sympatric does not

• Allopatric occurs in plants, sympatric in animals

• Allopatric is faster, sympatric is slower

• Allopatric produces more species, sympatric fewer

Which of the following best describes divergent evolution?

• Related species evolve different traits in different environments

• Unrelated species evolve similar traits in similar environments

• Species evolve to become extinct

• Species evolve to become more similar to each other

What is an example of divergent evolution mentioned in the presentation?

• Darwin's finches evolving different beak shapes

• Sharks and dolphins having similar body shapes

• Hummingbirds and flowers coevolving

• Penguins and seals both having flippers

Convergent evolution occurs when:

• Unrelated species evolve similar traits due to similar environments

• Related species evolve different traits in different environments

• Species evolve together in response to each other

• Species evolve to become extinct

Which pair of organisms demonstrates convergent evolution?

• Sharks and dolphins

• Cheetahs and gazelles

• Hummingbirds and flowers

• Darwin's finches on different islands

What is coevolution?

• When two species evolve together in response to changes in each other

• When a species evolves without any external influences

• When a species stops evolving

• When two species compete until one goes extinct

Which of the following is NOT an example of coevolution mentioned in the presentation?

• Hummingbirds and flowers

• Cheetahs and gazelles

• Sharks and dolphins

• Predator and prey relationships
