Evidence for Evolution Review

Front

What are vestigial structures?

Back

Structures that have no apparent function and are remnants of organs that had a function in ancestral species.

Front

What is an example of homologous structures?

Back

The forelimbs of a human and the wings of a bat.

Front

Which of the following is NOT a vestigial structure in humans?

Back

Heart.

Front

What role does biochemical evidence play in supporting the theory of evolution?

Back

It demonstrates that organisms with a closer evolutionary relationship have more similar DNA and proteins.

Front

What do analogous structures indicate?

Back

Similar Environment.

Front

Define evolution.

Back

The change in the heritable characteristics of biological populations over successive generations.

Front

What is natural selection?

Back

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

Front

What are fossils?

Back

Preserved remains or traces of ancient organisms that provide evidence for evolution.

Front

What is the significance of DNA in evolution?

Back

DNA carries genetic information that can change over time, leading to evolution.

Front

What is the difference between homologous and analogous structures?

Back

Homologous structures arise from a common ancestor, while analogous structures arise from similar environmental pressures.
