(Q4) LS - Evidence of Evolution

Front

What is a structure that is similar across species?

Back

Homologous structures are similar in different species, indicating a common ancestry.

Front

What are structures with the same parts but different functions?

Back

Homologous structures suggest that organisms share a common ancestry.

Front

What inference might paleontologists make if modern organisms have many homologous structures?

Back

The organisms have a common ancestor.

Front

What does Darwin's theory of evolution suggest?

Back

Species change over time.

Front

What is an example of a vestigial structure?

Back

The flightless cormorant has wings but cannot fly.

Front

What are vestigial structures?

Back

Structures that have lost their original function through evolution.

Front

What is adaptive radiation?

Back

The process where organisms diversify rapidly into a variety of forms to adapt to different environments.

Front

What is the significance of fossil evidence in evolution?

Back

Fossils provide evidence of how species have changed over time and can show common ancestry.

Front

What is the difference between homologous and analogous structures?

Back

Homologous structures share a common ancestry, while analogous structures have similar functions but different evolutionary origins.

Front

What is natural selection?

Back

The process where organisms better adapted to their environment tend to survive and produce more offspring.
