Year 10 Evolution

What is evolution?

• A. The process of natural selection

• B. The process of acquiring traits

• C. The process of genetic mutations

• D. The process of adapting to the environment

What was the main difference between Lamarck and Darwin's theories of evolution?

• a) Lamarck believed in the inheritance of acquired characteristics, while Darwin did not.

• b) Darwin believed that evolution occurs gradually, while Lamarck believed in sudden changes.

• c) Lamarck believed in the concept of common descent, while Darwin did not.

• d) Darwin believed in the use and disuse of organs, while Lamarck did not.

According to Lamarck's theory of evolution, how do organisms acquire new traits?

• A. Through natural selection

• B. Through genetic mutations

• C. Through use or disuse of certain organs

• D. Through random chance

According to Darwin's theory of evolution, what is the driving force behind evolution?

• A. Genetic mutations

• B. Use or disuse of certain organs

• C. Random chance

• D. Natural selection

Which of the following best describes the concept of natural selection?

• A. Organisms try to adapt to their environment

• B. The environment causes organisms to change

• C. Organisms that are best adapted to their environment survive and reproduce

• D. Random mutations cause changes in organisms

Which of the following is an example of natural selection?

• A. A giraffe that stretches its neck to reach leaves

• B. A lion that learns to hunt in a pack

• C. A bird that has brightly coloured feathers to attract a mate

• D. A moth that develops resistance to pesticides

Which of the following is an example of Lamarck's theory of evolution?

• C. A bird developing a longer beak to reach food in a tree

• D. A plant growing taller to get more sunlight

According to Darwin's theory of evolution, why do some individuals in a population have a better chance of survival?

• A. Because they actively try to adapt to their environment

• B. Because they have a greater need to survive

• C. Because they are born with traits that make them better adapted to their environment

• D. Because they are more intelligent than other individuals

Which of the following is NOT a requirement for natural selection to occur?

• a) Genetic variation

• b) Heritability

• c) Overproduction of offspring

• d) Use and disuse of organs
