Evolution

Front

What is Natural Selection?

Back

Natural Selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring.

Front

What is a common ancestor?

Back

A common ancestor is an ancestral species from which two or more different species have evolved.

Front

What does the tree of life represent?

Back

The tree of life represents the idea that all living organisms are related through common ancestry.

Front

What is Convergent Evolution?

Back

Convergent Evolution is the process where organisms from different ancestors develop similar traits due to adapting to similar environments.

Front

What is Divergent Evolution?

Back

Divergent Evolution is the process where two or more related species become more dissimilar over time, often due to different environments.

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.

Front

What is the significance of DNA analysis in evolution?

Back

DNA analysis helps scientists understand genetic relationships and evolutionary history among different species.

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, harmful, or neutral, influencing natural selection.

Front

What is adaptive radiation?

Back

Adaptive radiation is the process by which organisms rapidly diversify into a variety of forms to adapt to different environments.

Front

What is the difference between homologous and analogous structures?

Back

Homologous structures are similar due to shared ancestry, while analogous structures are similar due to convergent evolution, not common ancestry.
