Exploring Natural Selection and Evolution Concepts

Why do mutations occur?

• Due to environmental changes

• As a result of natural selection

• Randomly in the genetic code

• Because organisms want to evolve

What are the small random changes in the genetic code called?

• Selections

• Evolutions

• Mutations

• Adaptations

What allows the circle organism with a mutation to survive when the berry trees die?

• Its larger size

• Its ability to fly

• Its sharper teeth

• Its faster speed

What is the primary cause of natural selection?

• All organisms eventually evolving

• Environmental pressures favoring certain traits

• Organisms choosing to adapt

• The strongest always survive

What does the environment do in the process of natural selection?

• Physically selects organisms

• Creates new mutations

• Favors better-adapted organisms

• Changes genetically

What is the gradual change of species due to natural selection called?

• Mutation

• Adaptation

• Evolution

• Selection

How does a new species arise according to the video?

• By moving to a new environment

• Through the use of technology

• When its genes are too different to reproduce with the original species

• Through selective breeding

What can cause a previously advantageous adaptation to become disadvantageous?

• A change in the environment

• A new mutation in the species

• The development of technology

• The extinction of the species

What happens to the original species if a new species fails to adapt?

• It migrates to a new environment

• It continues to live and reproduce

• It becomes extinct

• It evolves into a new species

What term does the narrator prefer to use instead of 'survival of the fittest'?

• Survival of the luckiest

• Survival of the just good enough

• Survival of the strongest

• Survival of the most adapted
