Extension (for Year 10 and 11 students)
So how do animals and plants get their adaptations in the first place?
The answer lies in Natural Selection…
We are all unique – humans have different eye colours, hair, skin, heights, and shapes.
In nature, plants and animals also are unique. But when the environment changes, the plants and animals that have traits which allow them to better survive are the ones that will successfully reproduce and pass on the features that helped them survive. This is called ‘Natural Selection’. As this process continues over many generations, organisms come to have traits that make them very well suited to their environments. These traits are what we call ‘adaptations’.
An example of genetic diversity within a species is shown here: these are all the same type of flower, Paper Daisies, but they can be different colours!
