Evidence for Evolutiom

Which of the following lists the levels of classification in the traditional hierarchy of taxa in the correct order?

• Kingdom, Phylum, Class, Order, Family, Genus, Species

• Kingdom, Family, Order, Class, Phylum, Genus, Species

• Domain, Kingdom, Phylum, Class, Family, Order, Species

• Phylum, Kingdom, Order, Family, Class, Genus, Species

What is a limitation of the traditional classification system?

• • It does not consider evolutionary relationships

• • It groups organisms only by physical characteristics

• • It can result in incorrect placements due to convergent evolution

• • All of the above

What is an advantage of a classification system that corresponds to evolutionary relationships?

• It groups organisms based on common ancestry

• t only considers physical traits

• It ensures organisms with similar functions are grouped together

• It disregards DNA evidence

What is the definition of a homologous structure?

• • A structure with a similar function but different evolutionary origins

• A structure inherited from a common ancestor but adapted for different functions

• A structure found only in mammals

• A structure that has identical form and function across species

What is the pentadactyl limb?

• A type of analogous structure

Which organisms possess a pentadactyl limb?

How do variations in the pentadactyl limb structure relate to function?

• The limbs serve the same function across all species

• The number of bones in the limb changes completely

• Modifications allow different species to specialize for movement in different environments

• The limb does not evolve in response to function

What is the definition of divergent evolution?

• • The process where unrelated species develop similar traits due to similar environments

• • The process of species losing traits over time

• Evolution that leads to extinction

• The process where species with a common ancestor evolve different traits over time

How does divergent evolution explain differences in pentadactyl limb function?

• The structure remains unchanged across species

• It allows the limb to be modified for different functions in different environments

• It eliminates structures that are not useful in all species

• It causes identical evolution in all species with the limb
