Unit 4 Evolution Flashcard

Front

Why is the mouse population changing over time?

Back

The hawks eat more light mice than dark mice because they can see the light mice more easily.

Front

A theory has significant evidence to support it. True or False?

Back

True

Front

The passing of genetic traits (DNA) from parent to offspring is __________.

Back

Heredity

Front

Do organisms 'decide' to evolve and change?

Back

No, they change because of natural selection.

Front

A slight difference in an inherited trait between individual members of the same species is called __________.

Back

Variations.

Front

What is natural selection?

Back

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

Front

What is evolution?

Back

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

Front

What are adaptations?

Back

Traits that enhance an organism's ability to survive and reproduce in its environment.

Front

What is the difference between homologous and analogous structures?

Back

Homologous structures are similar due to shared ancestry, while analogous structures are similar due to convergent evolution.

Front

What is genetic variation?

Back

Differences in DNA among individuals, which can lead to variations in traits.
