 Instead of digesting it, they formed a symbiotic relationship. This led to the
 first nucleated organisms, marking an evolutionary milestone. This event lead
 to the development of plants, fungi and also ultimately humans.

 Now delving deeper into the realm of sourdough, it can likely be traced to aforementioned
 Ancient Jordan~\cite{jordan+bread}. Looking at the earth's timeline sourdough
