Pick a specific microbiome (i.e. skin, mouth, gut, reproductive) and discuss interesting points and how it is important to human health/diversity/etc.
Here you can discuss any aspect of the microbiome that you like. Whatever is of most interest to you personally for example the uniqueness of an individual’s microbiome or disease states due to disruptions in bacterial communities, etc.
Find a recent (2015 or newer) primary research article that investigates some aspect of the microbiome environment that you discussed in question 2 and discuss the findings and how it has increased our understanding of the microbiome.
