Biology is a fascinating and diverse subject which will have taught you many things already, such as how your body works and how living things interact in the world around you. TV, the news and the media are filled with new medical issues, such as COVID, Ebola, Zika, dementia and global challenges such as climate change, all of which can be solved by biologists. Amazing new discoveries in genetics are opening up surprising possibilities that a decade ago would have been considered almost a fantasy. Our advancing understanding of medicine, health and disease, genetic engineering and conservation to name but a few mean that it is an exciting time to study biology.
