Evolución

The transcript explains how the diversity of life on Earth has evolved from a common ancestor over millions of years. It highlights that at the genetic level, evolution involves changes in the frequency of certain gene types within a population over time.

What is the source of the diversity of life on Earth?

• Different environmental conditions

• Human intervention

• A common ancestor

• Random mutations

Which of the following is NOT a factor in the development of life diversity?

• Artificial selection

• Genetic mutations

• Common ancestry

• Inherited characteristics

How does evolution affect gene types at the genetic level?

• All gene types become equally frequent

• Certain gene types become more frequent

• Gene types disappear completely

• Gene types remain constant

What assumption does evolution make about gene types?

• They all become extinct

• They become less frequent

• They remain unchanged

• They become more frequent

What is the definition of gene frequency in a population?

• A constant value over time

• A random occurrence

• A function of time

• An unchanging characteristic
