Are you ready to travel back in time and discover the amazing story of life on Earth? In this e-book, you will learn about the first living things that appeared on our planet, how they evolved and changed over billions of years, and how they gave rise to the diversity of life we see today. You will also learn how scientists use fossils to study the past, and how you can become a fossil hunter yourself!This e-book is divided into three main parts, each with a summary and a quiz to test your knowledge.
Here are the chapters you will find in each part: Part 1: The First Living Things- What are the first living things called?- How many cells do they have?- Where do they live?- What is the name of the green stuff that makes oxygen?- What is the name of the tiny animals that eat algae?In this part, you will learn about the simplest and oldest forms of life on Earth: bacteria and archaea.

Part 2: Fossils and Evolution- How long ago did they appear on Earth?- How do we know they existed?- What are fossils?- How are fossils formed?- What are some examples of fossils?- How do fossils help us learn about the past?- What is evolution?- How do living things change over time?In this part, you will learn how to measure time in geology, and how to read the history of life from rocks and fossils.
You will also learn about the theory of evolution, which explains how living things adapt to their environment and diversify into new species. Part 3: Multicellularity- What are some advantages of having more than one cell?- What are some disadvantages of having more than one cell?- What are some examples of multicellular organisms?- When did multicellular organisms appear on Earth?- How did multicellular organisms evolve from single-celled ones?- What are some challenges that multicellular organisms face?- How do multicellular organisms survive and reproduce?In this part, you will learn about the amazing transition from single-celled to multicellular life, which happened several times in different groups of organisms.
You will also learn about the different types of multicellular organisms, such as plants, animals, fungi, and algae, and how they cope with the challenges of living in complex bodies.
