Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the types of perturbations?Encompasses mutational, environmental, recombinational, and behavioral influences
2. What is the developmental buffering?Manifests as canalization, ensuring consistent phenotypic outcomes during development
3. What is robustness in evolution?Robustness means a living thing can keep the same traits even when genes change or the environment is different. It helps the organism stay reliable and functional.
4. Why do animals and plants need robustness?Robustness keeps important parts of the body working well even when surprises happen, like a sudden temperature change or a small genetic mistake. This helps them survive and pass on their traits.

Phenotype: The observable physical or biochemical characteristics of an organism.
Perturbation: An external or internal disturbance that challenges the stability of a biological system.
Canalization: The evolutionary process that stabilizes the expression of a phenotype despite genetic or environmental variation.
