I want to know the answer to the following question:
Why do cells of Myxobacteria migrate towards each other?
All the background I'm provided with is that "For example, about one in 10 cells migrate to the top of these fruiting bodies and differentiate into a specialised dormant state called myxospores, which are more resistant to drying and other adverse environmental conditions than are ordinary cells.". Is that enough to answer the question?
