2nd Task: Evidence of Evolution Test Review

Front

What is the evidence of common ancestry in forelimb bones of different species?

Back

The forelimb bones are similar in structure, indicating a common ancestor.

Front

Which species' DNA is most similar to the DNA of the toothed whale?

Back

Baleen Whale.

Front

Why do penguins have wings if they cannot fly?

Back

Penguins have a common ancestor that was able to fly.

Front

How can we determine the age of a fossil?

Back

By examining the depth of the fossil and studying the surrounding rock types.

Front

What is the significance of homologous structures in evolution?

Back

Homologous structures indicate common ancestry among different species.

Front

What does the term 'fossil record' refer to?

Back

The fossil record is the history of life on Earth as documented by fossils.

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 the role of mutations in evolution?

Back

Mutations introduce genetic variation, which can lead to new traits in a population.

Front

What is the difference between homologous and analogous structures?

Back

Homologous structures share a common ancestry, while analogous structures serve similar functions but do not share a common ancestor.

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.
