DNA Evidence for Evolution Quiz

What is a fundamental aspect of evolution according to the video?

• Unpredictable mutations

• Gradual and progressive change

• Instantaneous development of life

• Rapid changes in species

Why is the presence of DNA in all living things considered evidence for evolution?

• It shows that all life forms are identical.

• It suggests a common origin for all life.

• It proves that life is static.

• It indicates that DNA is unique to humans.

• All organisms have different genetic codes.

• The genetic code is unique to mammals.

• All living things use the same genetic code.

How do all living things 'speak the same language' according to the video?

• By sharing the same habitat

• By having identical DNA sequences

• By following the same genetic code

What does the presence of DNA in all living organisms suggest about their origin?

• They have a single common ancestor.

• They have no evolutionary connection.

• They were created simultaneously.

• They evolved independently.

What is the significance of the genetic code being universal?
