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)

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?

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?

During a biology class, Lily, Mia, and Nora were discussing about vestigial structures. They listed down some examples. Which of the following examples they discussed is a vestigial structure?

Hannah, Noah, and Daniel found some structures during their biology field trip. What type of structures could these be?

Jackson and Avery are studying genetics. They come across a statement that two organisms that are closely related would have

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?

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?

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)

James and Aria were studying about evolution in their biology class. They came across a concept and James asked Aria, 'How would you describe this evolution?'

Grace, Lily, and Mason are studying for their biology exam. They come across a question about animals living in different continents. They notice that Anteater/Armadillos of the Americas and the Pangolin of Africa, despite being geographically distant, have similar characteristics and are not close relatives. They live in similar environmental conditions. What can they deduce from this observation?

Mason, Nora, and Avery are studying the similarities of the structures of different species in their biology class. What do these similarities suggest?

James found a picture in his biology textbook and asked Luna, 'This picture is best known as?'

Hannah, Abigail, and Maya are on a field trip to a natural history museum. They come across a section dedicated to fossils. Hannah asks, 'Why do scientists look for fossils?'

Liam, Kai, and Grace are studying the embryonic stages of two organisms shown in a diagram.

Which of the following can they determine by observing the embryos shown in the diagram?

Mason, Avery, and Noah are studying for their biology exam. They come across a table showing the number of differences in amino acids in a protein called “Cytochrome C” when comparing humans to other organisms. 
They are trying to list the 4 closest human relatives based on this biochemical comparison. Can you help them?

Luna, Benjamin, and Aiden are studying different species of birds for their science project. They are comparing the DNA of different finches to a large tree finch. According to their research, which bird's DNA is most similar to a large tree finch?

Evelyn, Nora, and Aria are participating in a biology quiz. They are asked, 'Which three animals are most distantly related?'

During a school trip to the Natural History Museum, Emma, Kai, and Charlotte learned about the founder of modern evolution theory. They were told that _____ is considered to be the founder.

Lily, Priya, and Maya are studying biology and they come across the concept of homologous structures. They are trying to identify an example of a homologous structure. Which of the following would they correctly identify as a homologous structure?

During a school trip to the aquarium, Nora, Samuel, and Benjamin were observing a whale. Samuel noticed a peculiar structure in the whale and asked the guide about it. The guide explained that this structure suggests whales share a common ancestor with land-dwelling mammals. Which structure was Samuel referring to?

Fossils provide evidence of evolution because

The pelvic bone of whales is not needed for movement within the water. This is an example of a(n) ______________ structure.
