Sharon Moalem explores how organisms evolve over time and how those evolutions affect other organisms around them. What makes this relevant is the type of diseases Moalem looks at and how adaptations can have positive and negative effects on those organisms. He finds it interesting how some adaptations decrease the production of a certain element can be a positive for that organism. With many of the diseases going around today, humans have to find ways to combat those diseases. Like coronavirus. As people become vaccinated, their immune systems become aware of the virus and evolve to keep the body healthy. However, the world still can't find cures for adaptations like cancer. 

However, he helps discover why diseases exist in the gene pool and the basic answer is a mutation in DNA. Mutations happen randomly and sometimes often and it mixes up the reproduction of its genes.  An example of that today is the multiple variants of the covid 19 and how it affects humans differently.  

What makes these ideas significant is Moalem's conclusion that organisms are created and recreated happens every single day. Mutations help create different variations of species and it's again created. The way that organisms grow really affects the environment as a whole and it shows the connection that all organisms have to this day.
