7C Natural Selection

Front

What is natural selection?

Back

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

Front

Do organisms 'decide' to evolve?

Back

No, they change because of natural selection.

Front

What are variations in a species?

Back

Variations are the differences among individuals in a species, such as different traits like bird beaks.

Front

Why are advantageous traits more likely to be passed on?

Back

Because they are more likely to survive and reproduce.

Front

Where do adaptations come from?

Back

Adaptations come from mutations that give an organism an advantage in its environment and genetic recombination during meiosis.

Front

What is an example of natural selection in action?

Back

The change in mouse populations where light mice survive better in light environments due to predation.

Front

What role do mutations play in evolution?

Back

Mutations introduce new traits that can be advantageous, neutral, or harmful, influencing an organism's survival.

Front

What is genetic recombination?

Back

Genetic recombination is the process during meiosis where genetic material is shuffled, creating new combinations of traits.

Front

How does the environment influence natural selection?

Back

The environment determines which traits are advantageous, affecting survival and reproduction rates.

Front

What is the significance of survival of the fittest?

Back

It refers to the idea that individuals with traits better suited to their environment are more likely to survive and reproduce.
