Evolution Practice

Front

What is Natural Selection?

Back

Natural selection is the process where organisms with favorable adaptations are more likely to survive and reproduce, leading to those adaptations becoming more common in the population over time.

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 evolve similar traits or adaptations independently, often because they occupy similar environments or ecological niches.

Front

What is Coevolution?

Back

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

Front

What is the role of geology in supporting biological evolution?

Back

Geology provides evidence of Earth's history, including the age of rocks and fossils, which helps scientists understand the timeline of evolutionary changes.

Front

What is the significance of anatomy in evolutionary biology?

Back

Anatomy helps in understanding the structural similarities and differences among species, which can indicate common ancestry and evolutionary relationships.

Front

What is embryology and its relevance to evolution?

Back

Embryology studies the development of embryos, revealing similarities in early development stages among different species, suggesting common ancestry.

Front

Why is astronomy not considered a supporting discipline for biological evolution?

Back

Astronomy focuses on celestial bodies and the universe, which does not directly provide evidence or insights into biological evolution and the history of life on Earth.

Front

What is an adaptation?

Back

An adaptation is a trait or characteristic that enhances an organism's ability to survive and reproduce in its environment.

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.
