Who wrote the book of "The origin of species"?

• Mr. Valencia

• Gregor Mendel
• Louis Pasteur
• Charles Darwin

What helps an orgamism survive it's environment?

• Increased predation risk.
• Lack of competition for resources.
• Adaptations that enhance survival.
• Limited access to food sources.

Who were the two scientists that introduced the idea of evolution through natural selection?

• Galileo Galilei and Johannes Kepler

• Charles Darwin and Alfred Russell Wallace

• Isaac Newton and Albert Einstein

• Marie Curie and Louis Pasteur

Why do giraffes with longer necks have an advantage in their environment?

• They can swim better.

• They can reach higher into trees for food.

• They can fly.

• They can run faster.

What do we call genetic differences between members of the same species?

• Variation

• Species uniformity
• Genetic stability
• Family members

What is the common ancestor of giraffes and okapis?

• An ancient animal with a shorter neck

• A dinosaur

• A modern-day elephant

• A bird

Why is there evolution of animals such as the lizards?

• Lizards evolve primarily due to genetic mutations unrelated to their environment.
• Lizards evolve due to natural selection and environmental changes due to climate change.

• Lizards do not evolve; they remain unchanged over time.
• Lizards evolve only because of human intervention and breeding.

How is variation passed on?

• Variation is passed on through learned behaviors.
• Variation is passed on through environmental factors.
• Variation is passed on through offsprings.

• Variation is passed on through social interactions.

What is one reason why many species might not have time to adapt to new environments?

• Plants are growing too fast.

• The sun is getting hotter.

• Human activities are changing environments too quickly.

• Animals are becoming lazier.

What can we do to help preserve the natural world?

• Build more cities

• Live in harmony with nature and protect habitats

• Ignore climate change

• Cut down more trees
