Front

What is the principle that states organisms with the most beneficial traits will survive?

Back

Survival of the fittest.

Front

What is gene flow in the context of biodiversity?

Back

Gene flow is the transfer of genetic variation from one population to another.

Front

Do organisms consciously decide to evolve?

Back

No, organisms change due to natural selection.

Front

What is the fossil record?

Back

The fossil record is the collection of life's remains found in sedimentary rock.

Front

What is speciation?

Back

Speciation is the formation of new and distinct species during the course of evolution.

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.

Front

What role does genetic variation play in evolution?

Back

Genetic variation is essential for natural selection, as it provides the raw material for evolution.

Front

What is the difference between allopatric and sympatric speciation?

Back

Allopatric speciation occurs when populations are geographically isolated, while sympatric speciation occurs without geographical isolation.

Front

How does environmental change affect biodiversity?

Back

Environmental change can lead to shifts in species distribution, extinction, and the emergence of new species.

Front

What is the significance of biodiversity in ecosystems?

Back

Biodiversity contributes to ecosystem resilience, productivity, and stability.
