Darwin and Evidence of Evolution

In a biology class, William and Lily were discussing about different structures in organisms. William suggested that structures with the same parts but different functions, like the wings of bats and the arms of humans, suggest that organisms share a common ancestry. Lily agreed and said this concept is known as what?

• vestigial structures

• homologous structures

• adaptive radiation

• fossil

Michael found a structure in an organism that seems to serve no purpose now. Elijah suggests that this vestigial structure likely once had a function in a(n)

• close relative of the organism

• early ancestor of the organism

• unrelated organism

• embryological stage of the organism

Evelyn, Anika, and Avery were studying for their biology exam. They came across a concept that some organisms that share a common ancestor have features that have different functions, but similar structures. They were trying to remember the term for this concept. Can you help them?

• vestigial structures

• analogous structures

• homologous structures

• fossil structures

In a biology class, Charlotte, Zoe, and Aria are studying the embryos of various organisms like chickens, frogs, and humans. They notice similarities in the development of these embryos which could indicate a common ancestor. What is this field of study called?

• natural selection

• embryology

• speciation

• evolution

Ava, Michael, and Benjamin went on a field trip to a geological park. They observed fossils in different rock layers. Based on their observations, which of these statements about the age of these fossils is most likely correct?

• Fossil A and C are the same age
  

• Fossil B is older than fossil C

• Fossils A is older than fossil B

• Fossil D is older than fossil C

Mia, Liam, and Luna went on a field trip to a geological site. They found several layers of fossils. Which statement best describes the fossils they found?

• The oldest fossils Mia, Liam, and Luna found can be found on the lower layers

• The oldest fossils Mia, Liam, and Luna found can be found at the top layers

• The youngest fossils Mia, Liam, and Luna found are always on the bottom layers

• Mia, Liam, and Luna cannot tell the age of any of these fossils

Benjamin, Daniel, and Hannah were studying about whales in their biology class. They learned that whales are aquatic mammals that contain a pelvis bone. Even though it does not aid in their movement, they understood that the function must have been used by a common ancestor of the whale. Thus, they referred to the pelvis as a(n)

• vestigial structure

• analogous structure

• homologous structure
