Has an animal saved your life? Studying Arctic birds helped resuscitate those suffering from hypothermia. An ECG on the 150kg heart of a humpback whale has extended the lives of patients with heart failure. Understanding giraffes' long necks has led to improved asthma treatment. Learning how animals survive and thrive has led to life-saving advances for human health. But we still have a long way to go. Intensive care doctor Matt Morgan looks at why animals can be the key to understanding how our bodies work - and how to fix them when they go wrong.

It all started with a Hob Nob. As Dr Matt Morgan, an intensive care consultant, examined a patient who had suffered a cardiac arrest after inhaling some biscuit crumbs, he saw a flock of birds fly past the window. They must inhale objects all the time when flying, how do they survive? he thought to himself. This began an investigation that spanned continents, species and millennia. For animal science has so much to teach us about human medicine. While some of the overlaps and parallels are obvious – we know how much DNA we share with primates, the first pig heart has been transplanted into a human – there is so much more that we have learnt from the animal world. For example, studying kangaroos, in particular the female’s three vaginas, has improved in-vitro fertilisation success rates. Watching how a giraffe breathes can help save the life of someone struggling with asthma. Investigating why birds that live in the frozen Arctic circle don’t freeze to death led to advances with treating hypothermia. Getting a ECG on the 150kg heart of a humpback whale was instrumental to keeping patients with cardiac failure living longer. We owe animals so much, it’s time to focus on examining how they live and what we still have to learn from them. Better shared understanding of how our species coexists with millions of others can lead to untold medical advances, help both humans and animals and improve the world for all creatures from single-celled bacteria to a 30,000 kg whale. Who knows, maybe a kiss from a frog will save your life?
