The Evolution of Spores

The evolution of spores was a critical step in the transition of plants on to land. This paper discusses developmental transitions that may have transferred the formation of the spore wall from the zygote to the spores. I enjoyed reading the paper and thought that it was a really interesting developmental transition.
