Natural Selection or Artificial Selection*

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. It is a key mechanism of evolution.

Front

What is Artificial Selection?

Back

Artificial Selection is the process by which humans breed plants and animals for particular genetic traits. It involves selecting specific individuals to reproduce based on desired characteristics.

Give an example of Natural Selection.

Back

An example of Natural Selection is the increase in the population of dark moths during the Industrial Revolution due to pollution, which made them less visible to predators.

Front

Give an example of Artificial Selection.

Back

An example of Artificial Selection is farmers choosing the largest corn kernels to plant for the next season's harvest.

Front

What role do pesticides play in Natural Selection?

Back

Pesticides can lead to Natural Selection by killing off non-resistant insects, allowing resistant insects to survive and reproduce, increasing their population over time.

Front

How does Artificial Selection differ from Natural Selection?

Back

Artificial Selection is driven by human choices, while Natural Selection is driven by environmental pressures and survival of the fittest.

Front

What is a key factor in Natural Selection?

Back

A key factor in Natural Selection is variation within a population, which allows some individuals to be more suited to their environment than others.

Front

What is the significance of genetic variation in Natural Selection?

Back

Genetic variation is crucial for Natural Selection as it provides the raw material for evolution, allowing populations to adapt to changing environments.

Front

What is selective breeding?

Back

Selective breeding is a form of Artificial Selection where specific plants or animals are chosen to reproduce based on desired traits.

Front

What is the outcome of Artificial Selection?

Back

The outcome of Artificial Selection is the development of new varieties or breeds with specific traits that are beneficial or desirable to humans.
