1. There are many possible hypotheses of how fungi originally evolved. Ranging from common ancestry of plants, to diverging as an entirely separate species have all been studied. One of the most surprising facts is that fungi is actually more similar to animals than that of plant cells. Containing similar cytoplasmic organelles and a like structure of DNA have caused speculation. The present theory is that some 965 million years ago a common ancestor of both fungi and animals diverged into the different algae and single celled organisms that we now know of today. Fungi would continue to evolve until their present fruiting bodies known today which occurred around 150 million years ago.
