Evolution

What is the term for the change in a population's genes over time due to natural selection and genetic variation?

Back

Evolution

Front

Who was the first person to explain that natural selection causes evolution within a population?

Back

Charles Darwin

Front

What term describes the differences in traits among individuals in a population, such as tail length in tigers?

Back

Variations

Front

In a snowy environment, which rabbit population is likely to increase if one is better adapted?

Back

The white rabbit population will likely increase.

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

What is the significance of genetic variation in a population?

Back

Genetic variation is crucial for natural selection as it provides the raw material for evolution.

Front

How does natural selection lead to evolution?

Back

Natural selection leads to evolution by favoring individuals with advantageous traits, allowing them to reproduce and pass those traits to the next generation.

Front

What is the role of environmental factors in natural selection?

Back

Environmental factors determine which traits are advantageous, influencing which individuals survive and reproduce.

Front

What is the difference between natural selection and artificial selection?

Back

Natural selection occurs naturally based on environmental pressures, while artificial selection is the intentional breeding of organisms by humans.
