What is evolution?

Back

Evolution is the process by which populations of organisms change over generations through variations in traits, driven by natural selection, mutation, and genetic drift.

Front

What is natural selection?

Back

Natural selection is the mechanism by which individuals with beneficial traits are more likely to survive and reproduce, leading to the increase of those traits in the population.

Front

What are beneficial traits?

Back

Beneficial traits are characteristics that enhance an organism's ability to survive and reproduce in its environment.

Front

What is divergent evolution?

Back

Divergent evolution occurs when two or more related species become more dissimilar over time, often due to different environmental pressures.

Front

What is convergent evolution?

Back

Convergent evolution is when unrelated species develop similar traits or adaptations due to similar environmental challenges.

Front

What is coevolution?

Back

Coevolution is the process where two or more species influence each other's evolution, often seen in predator-prey relationships or mutualistic interactions.

Front

What is artificial selection?

Back

Artificial selection, or selective breeding, is the process by which humans breed plants and animals for specific traits.

Front

What are homologous structures?

Back

Homologous structures are anatomical features in different species that share a common ancestry, even if they have different functions.

Front

What is the significance of the fossil record?

Back

The fossil record provides evidence of past life forms, showing how organisms have evolved over time and how environments have changed.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence of an organism, which can lead to new traits and contribute to genetic diversity.
