The most recent ancestral form or species from which two different species evolved is known as ________________________.

• a common ancestor.
• an embryonic stage.
• development.
• evolution.

NGSS.MS-LS4-2

Which of these cases provides embryological evidence that two species share a common ancestor?

• two species with very similar DNA

• two species with different body structures

• two species with different structures that have similar functions

• two different species with similar patterns of early development

Two species might have similar skeletal structures that have different functions. What do these types of structures suggest about the relationship between the two species?

• Common structures with different functions suggest that the species live in the same habitat.

• Common structures with different functions suggest that the species do not share a common ancestor.

• Common structures with different functions suggest that one of the species never learned how to use the structure properly.

• Common structures with different functions suggest that the species share a common ancestor that also had a similar structure.

Snakes have traces of leglike structures that are not used for movement. Which inference is supported by this fact?

• Snakes do not have ancestors.

• Snakes are an example of transitional fossils.

• Snakes share a common ancestor with animals that have legs.

• Snakes and animals that have legs are part of the same species.

This image shows the development of various organisms and how they share a common ancestor because of similarities in development.  It is called:

• homologous structures
• evolution

• natural selection

• embryology

Tara is comparing the embryos of parrotfish and salamanders. Although the adult organisms look very different, the embryos follow similar developmental pathways. What does this suggest?

• that parrotfish and salamanders are found in the fossil record

• that parrotfish and salamanders have the same genetic makeup

• that parrotfish and salamanders likely share a common ancestor

• that parrotfish and salamanders use their organs for different functions
