There is no reason for there to be multi- cellular organisms. Protozoa can flourish quite nicely on their own. And there is a real question how one could get from undifferentiated masses of cells to specialized systems, like nerve cells, musculature, and circulatory cells in complex systems. The genetic changes that accrue are incremental: what is the status of a quarter of a nervous system? Then, of course, there are odd little species rituals, like the spawning grounds phenomenon: all eels in the Atlantic return to the Sargasso Sea (part of the Caribbean) to spawn, and then their offspring repopulate the Atlantic coasts. Salmon return to spawning grounds against river currents, and their offspring return to the sea. How do such things accrue incrementally? And since there is always a point of origin, what happens while building a population with the shared trait? It is hard to believe that the first Sargasso eels or upstream salmon had an advantage over those fishes who stayed put. Anyway, either there is some underlying Intelligence to the process, or it is just a hodge podge, and algae may just as well take over the earth in the long run.
