Grade 10 Science Module: Evidence of Evolution

This Self-Learning Module (SLM) is prepared so that you, our dear learners, can continue your studies and learn while at home. Activities, questions, directions, exercises, and discussions are carefully stated for you to understand each lesson.

Each SLM is composed of different parts. Each part shall guide you step-by-step as you discover and understand the lesson prepared for you.

Pre-tests are provided to measure your prior knowledge on lessons in each SLM. This will tell you if you need to proceed on completing this module or if you need to ask your facilitator or your teacher’s assistance for better understanding of the lesson.

I Evolve, You Evolve, and They Evolve!

You may have met the term “evolve” in some popular comic series or video games and somehow developed an idea of what the word means. In this module, we will find out its meaning in biology and its role in tracing species’ development.

Some organisms may look the same but have distinct differences from each other, others may not be related to each another, but they have similar functional features and characteristics. Some animals before are very different from the animals we have now.

This module will take you on a historic voyage that has changed our view of the history of life. Come and join in this exploration and discover what Charles Darwin and other scientists have written about how species evolve with time!

After going through this module, you should be able to:

1. Explain how fossil records, comparative anatomy, and genetic information provide evidence for evolution;

2. Compare homologous, analogous, and vestigial structures and analyze their significance in evolutionary history; and

3. Identify the effect of gene mutation on the evolution of the species.

Going through this module can be a meaningful learning experience. All you need to do is make use of your time and resources efficiently. To do this, here are some tips for you:

1. Take the pretest (What I Know) before reading the rest of the module.

2. Take time in reading and understanding the lesson. Follow instructions carefully. Do all activities diligently. It is better to be slow but sure than to hurry and miss the concepts you are supposed to learn.

3. Use a separate sheet of paper for your answers in each activity or assessment. Don’t forget to write your name. Label it properly.

4. Try to recall and connect the ideas about the lessons that you had in the lower years. Use the concept discussed in the lesson to explain the results of activities or performance task.

5. Be honest. When doing the activities, record only what you have really observed. Take the assessments after each activity, but do not turn to the Answer Key page unless you are done with the entire module.

6. Don’t hesitate to ask. If you need to clarify something, approach or contact your teacher or any knowledgeable person available to help you. You may also look into other references for further information.

7. Take the post-test prepared at the end of the module, so you can assess how much you have learned from this module.

8. You can check your answers in the activities, self-assessments, and post-test after you finished the entire module to know how much you have gained from the lesson and the activities.
