Evidence for Evolution Quiz

According to this data, the unknown bacterial species is most closely related to: 

• Species I
• Species II
• Species III
• Species IV

Recently, scientists have been able to use ___________to find common proteins and amino acids to determine how closely related species are.

• DNA

• Vestigial structures

• Fossils

• Homologous structures

The similarities of bone structure in the diagram provide evidence of what?

• The organisms probably use there forelimbs for the same thing.

• The organisms evolved from a common ancestor.

• The organisms have the same DNA.

• All vertebrate species have identical forelimbs.

_________________ show clear changes in an organism over time, the environment organisms lived in, the time period the organism lived in, and where the organism lived.

• DNA

• Vestigial structures

• Fossils

• Homologous structures

Which is not evidence for evolution?

• Many animals have homologous structures due to common ancestry

• Organisms descended from a common ancestor share similar DNA

• We can observe changes in life forms by observing the fossil record
• All of these are evidence for evolution

Which two species are most closely related?

• 1 & 3

• 1 & 4

• 2 & 3

• 3 & 4

All the animals to the right of the hagfish would have the common characteristic of -

• Fur
• Claws or nails
• Lungs
• Jaws

According to this cladogram, primates are most closely related to -

• Amphibians
• Rodents and rabbits
• Crocodiles
• Birds

What is the purpose of a cladogram?

• To map the ancestral relationships and shared traits of different organisms.

• To trace the inherited traits of a single species over time.

• To check the likelihood of an offspring having a particular trait.

• To monitor mutations that arise among different populations.

What do both the squirrel and lion have in common that the other animals do not?

• They are both vertebrates

• They both have lungs

• They are both mammals

• They both lose their canine teeth.
