Environmental Science Second Trinal

What is the primary mechanism that drives evolution?

• Mutation

• Natural selection

• Genetic drift

• Artificial selection

Which process introduces new genetic variations into a population?

• Genetic drift

• Mutation

• Gene flow

• Natural selection

What is the term for the process where organisms better adapted to their environment tend to survive and reproduce more successfully?

• Speciation

• Genetic drift

• Natural selection

• Artificial selection

What role do mutations play in evolution?

• They create new genetic variations.

• They eliminate weak individuals from a population.

• They prevent natural selection.

• They reduce biodiversity.

Who is known as the 'Father of Evolution'?

• Gregor Mendel

• Charles Darwin

• Alfred Wallace

• Jean-Baptiste Lamark

What does the term 'descent with modification' mean?

• All organisms have evolved from common ancestors with changes over time.

• Only the strongest organism survives.

• Evolution occurs in a single generation.

• Traits do not change over time.

When a population experiences a drastic reduction in size due to a natural disaster or human activity, leading to a loss of genetic variation, it is known as:

• Bottleneck effect

• Founder effect

• Natural selection

• Gene flow

Which of the following must occur for evolution to take place?

• A large population size

• Identical traits among individuals

• Genetic variation within population

• No environmental changes

What is speciation?

• The extinction of a species

• The process of migration

• The formation of a new species

• A sudden change in an organism's DNA

The process in which organisms with beneficial adaptations survive and reproduce more successfully is called…

• Adaptation

• Speciation

• Natural Selection

• Genetic Drift
