What is the significance of DNA similarity in evolution?

Back

DNA similarity indicates how closely related different species are, reflecting their evolutionary history.

Front

What is the role of mutations in evolution?

Back

Mutations are changes in DNA that can lead to new traits, which may be beneficial, neutral, or harmful, influencing evolution.

Front

What is speciation?

Back

Speciation is the process by which new species arise from existing species due to evolutionary changes.
