Evidence Corrective

A bat wing and a butterfly wing are both used for flying but they are made differently. What type of structure is this?

• Homologous structure

• Analogous structure

• Vestigial structure

• Fossil structure

A human arm and a whale fin have similar bone structure but the whale fin is used for swimming and the arm is used for reaching and grabbing. What type of structures are these?

• Homologous structures

• Analogous structures

• Vestigial structures

• Fossil structures

When comparing the DNA of two different organisms, the more differences in the DNA base pairs the more-

• Closely related they are.

• Distantly related they are.

• It doesn't prove anything.

• They look alike.

The moth wing and the bat wing are example of structures.

(a)  

• Analogous
• Homologous
• Vestigial
• Fossil

What type of evidence is shown with the diagram above?

• Molecular

• Anatomical

• Embryological

• Fossil

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.

Serves no useful purpose in the modern organism but did in its ancestral form.

• Analogous Structure

• Vestigial Structure

• Homologous Structure

• Adaptation

How do fossils provide evidence that evolution has happened on Earth?

• Fossils show how the sizes of certain animals has changed drastically over millions of years
• Fossils show that some species have gone extinct
• Fossils show how life forms present today are different than those from the past
• Different sedimentary rock layers provide evidence for how the environment has changed over time

Which layer is the youngest

• 1
• 2
• 3
• 4

Which species’ DNA is most similar to the DNA of the toothed whale? 

• Hippopotamus 
• Baleen Whale
• Grazing Mammals
• Camels
