Unit 7: Evolution Test Review

Front

What is evolution?

Back

Evolution is the process by which different kinds of living organisms develop and diversify from earlier forms during the history of the earth.

Front

What did Charles Darwin conclude about evolution?

Back

Darwin concluded that evolution is due to a response to environmental changes.

Front

What is adaptive radiation?

Back

Adaptive radiation is the process by which organisms diversify rapidly into a variety of forms to adapt to different environments, as seen in Darwin's finches.

Front

What evidence do homologous structures provide?

Back

Homologous structures provide evidence of common ancestry among different species.

Front

What is a cladogram?

Back

A cladogram is a diagram that shows the evolutionary relationships among various biological species based on similarities and differences in their physical or genetic characteristics.

Front

What is the significance of beak depth in Darwin's finches?

Back

Beak depth in Darwin's finches is significant as it indicates adaptation to different food sources and survival advantages during environmental changes.

Front

What does a fossil record indicate?

Back

A fossil record indicates the historical sequence of life on Earth and can provide evidence for evolutionary changes over time.

Front

What is natural selection?

Back

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to variations in traits among individuals.

Front

What is the role of environmental changes in evolution?

Back

Environmental changes can create new challenges and opportunities, leading to adaptations in species over time.
