Consider the phylogeny (Fig. 34.15) below. Imagine that the trait "complex multicellular fruiting bodies" actually was present in the common ancestor indicated by the arrow

What
would its presence in the common ancestor mean for the evolution of fruiting bodies in the
group Dikarya?
A. The Glomeromycetes lost complex
multicellular fruiting bodies.
B. The group Dikarya has members that
didn't evolve complex multicellular fruiting
bodies.
C. The group Dikarya has members that lost
the trait of complex multicellular fruiting
bodies.
D. Because only one trait can evolve at a
node, regular septa would have evolved at
some other place on the phylogeny.
