Front

Why is empirical evidence important in scientific explanations?

Back

It provides a cumulative body of observations that support scientific explanations.

Front

What happens to a species that cannot adapt to a changing environment?

Back

The species may become extinct.

Front

What is fossil evidence?

Back

Fossil evidence is the remains or traces of past life forms preserved in rock, which provide information about the history of life on Earth.

Front

What is the significance of fossil evidence in understanding evolution?

Back

It provides a record of past life forms and their changes over time.

Front

How does the inability to adapt to environmental changes affect a species' survival?

Back

It may lead to the extinction of the species.

Front

What is evolution?

Back

Evolution is the process by which species change over time through adaptations to their environment.

Front

What are environmental factors?

Back

Environmental factors are external elements that can influence the survival and reproduction of organisms, such as climate, food availability, and predators.

Front

How can environmental factors influence evolution?

Back

They can lead to changes in traits that enhance survival, such as a population of rabbits becoming faster to escape predators.

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.
