What Thrives Inside; The World Within the Gut
We all have bacteria in our guts, and so do birds. These bacteria are good for us in many ways, and help to digest food. We often see similar groups of bacteria in the guts of related animals. But it’s not clear why this is. It could be because of the food each animal is eating, or how similar the animals are. It could even be a result of how closely together they live. We performed an experiment to try to work out which one was the cause but the results were not as simple as we hoped. Here, we explain the steps we took to try to answer this question.
