Putting It Together: Introduction to Biology

Biology is the study of life. As we’ve learned, this field covers a broad scope of subjects. As you progress through this course, you’ll gain the knowledge you need to make informed decisions. Let’s think back to the articles Cristina encountered at the beginning of this module: how could a knowledge of biological principle help with her understanding of each article?

Think about It

Cristina read an article about some of the world’s weirdest animals. What biological principle would help her understand why these animals have the features they do?

The next article Cristina read talked about GMOs (genetically modified organisms) and the risks they have. What biological principle would help her understand the potential risks of genetically modified foods?

Cristina then looked at an article about the paleo diet. What biological principle would help her understand the pros and cons of an extreme diet?


It is tempting to view different topics as completely separate, but in fact the ideas we cover in this course are often connected to one another. If you don’t retain the vocabulary from module to module, those connections can be missed. As you continue on, remember to come back and review the terms you’ve learned in order to increase your depth of knowledge.
