Unit 7 DNA & Evolution/Natural Selection Vocabulary Quiz

Two different organisms have similar body parts that serve the same function but have evolved separately.

• Analogous Structures

• Homologous Structures

• Vestigial Structures

_______________ parts of different organisms that have a similar structure, but may serve different functions. These structures are believed to have evolved from a common ancestor, and can give clues about the evolutionary history of a species.

• Vestigial Structures

• Homologous Structures

• Analogous Structures

• • Divergent Evolution

__________________are body parts or organs in an organism that have lost their original function during evolution. These structures used to be helpful to the organism's ancestors, but as the organism's environment changed, they became unnecessary.

• Homologous Structures

• Analogous Structures

• • Convergent Evolution

• Vestigial Structures

A ______________ is a theoretical organism from which two or more different species are believed to have evolved. It is like a grandparent to two different species, like how humans and chimpanzees are thought to have a common ancestor.

• • Natural Selection

• Common ancestor

• • Divergent Evolution

____________ is a process where organisms that are better suited to their environment have a greater chance of surviving and reproducing. This means that over time, traits that help individuals survive, like camouflage for hiding from predators or sharp teeth for catching prey,

• Natural selection

• Carrying Capacity

• Vestigial Structures

• • Divergent Evolution

NGSS.MS-LS1-4

_________ is a process where a single species evolves into two or more different species over time. This happens when the original population of a species becomes isolated in different environments or faces different challenges, causing them to adapt in different ways.

• • Common Ancestor

• • Natural Selection

• Homologous Structures

• Divergent evolution

NGSS.MS-LS4-4

____________________ is when different species develop similar traits or features even though they are not closely related. This happens because they face similar environmental pressures and have to adapt in similar ways.

• Convergent evolution

• • Divergent Evolution

• Carrying Capacity

• Homologous Structures

______the process by which humans intentionally breed organisms with desired traits in order to produce offspring with those same traits.

• Artificial selection

• Natural Selection

• Natural variation

• Gene Pool

_____the inherent diversity and differences that exist among individuals of the same species. It encompasses the range of traits, behaviors, and characteristics that are shaped by genetic, environmental, and random factors.

• Natural variation

• Natural Selection

• Selective Breeding

• Mutation
