We enjoy a wide variety of books in Year 6. We are currently reading On the origin of species by Sabina Radeva. It’s a non-fiction book that explains the findings of Charles Darwin. Charles Darwin was an English scientist who studied nature. He is known for his theory of evolution by natural selection. According to this theory, all living things are struggling to survive. The living things that have the most helpful traits for their environment tend to survive. These living things then pass along their helpful traits to their young. In this way, animals change, or evolve, over hundreds of years. We’ve learned a lot about evolution, adaptation and variation.
Here are ten fun facts we learned:
- Dragonflies existed before dinosaurs.
- Birds evolved from dinosaurs.
- The biggest Tyrannosaurus rex fossil ever discovered was unearthed in Canada in 2019. It was 42 feet long and weighed nearly 10 tons.
- Whales used to have legs and be able to walk on land.
- Humans develop a tail while they are in the uterus but it dissolves before they are born.
- It took Charles Darwin 20 years to write his book about the theory of evolution.
- No two animals (even of the same species and family) are exactly the same.
- There are 340 different breeds of dog, all of which evolved from a wild wolf that lived 40,000 years ago.
- Instinct plays a crucial role in natural selection. For example, birds instinctively know that they must travel to hotter climes in the winter.
- We’ll probably never know about all of the species of plants and animals that have existed over the lifetime of Earth.
