Key Questions
What do we already know about life cycles and habitats?
I can describe the process of reproduction as part of a life cycle. I can describe how things live in a habitat to which they are suited and know that changes to these habitats may pose a danger to living things. I can use classification keys to help group, identify and name living things.
How and why do things evolve?
By looking at fossils, we know that living things used to look different to how they do now. In the natural world, things compete with one another and the species that change to suit their environment are more likely to succeed, reproduce and pass on these characteristics to future generations. Over time, these characteristics help survival become more common and a species gradually changes.
What is natural variation?
Charles Darwin observed that, although individual species were similar, they were not exact copies of one another. Natural variation like this can lead to offspring being more likely or less likely to survive in their environment.
What is adaptation?
Adaptation is when things evolve to overcome challenges in their environment e.g. by adapting their behaviour. Birds that adapted to migrate around the world to find weather and food sources to suit them are more likely to survive than those who did not migrate. Animals may learn to live in packs in order to be more successful and safer when hunting.
Evolution and Inheritance - Y6
To be able to identify how animals and plants are adapted to suit their environment in different ways and that adaptation may lead to evolution. To be able to recognise that living things have changed over time and that fossils provide information about living things that inhabited the Earth millions of years ago. To be able to recognise that living things produce offspring of the same kind, but normally offspring vary and are not identical to their parents.
Charles Darwin (1809 -1882) was an English naturalist whose
scientific theory of evolution by natural variation or selection became the foundation of
modern evolutionary studies.
