In the last few weeks, Lower III have started their unit on Evolution and Inheritance. They have carefully observed fossils, discovered what the job of a palaeontologist involves and learnt about the life and work of Charles Darwin. 

One of Darwin’s key discoveries that led him to his theory of Evolution was observing the Finches that lived on the different islands of the Galapagos. He realised that while they were all finches they had changed over time and developed different beaks depending on the food sources available on the islands. 

So, to discover more about what types of food the finches may have eaten, the Lower III students went about investigating a number of different beaks! Once they had tested out each beak they reflected on the results and suggested possible food that type of finch may eat. 

For example: Birds that have large squared beaks would eat berries and large insects, but would not be able to eat small seeds and ants as they could not grip them. – by Kaashwi, Beatrice and Flossie
