I can explain what fossils are and how they provide evidence that species change over time.
Fossils show that species change over time
I can explain what fossils are and how they provide evidence that species change over time.
Lesson details
Key learning points
- Fossils provide evidence about organisms from long ago and their habitats.
- All fossils are the mineralised remains of once-living organisms or of traces left behind by organisms.
- Fossils show that some species have gone extinct.
- Fossils show that the features of some species have changed over time.
- There are limitations to the conclusions and explanations that can be made from fossil evidence.
Common misconception
Most students will be aware that bones can become fossilised but not realise that other remains such as wood or footprints can also become fossils too.
This lesson contains a broad range of examples of the types of remains that can become fossilised.
