Did terrestrial diversification of amoebas (amoebozoa) occur in synchrony with land plants?

Evolution of lineage diversification through time is an active area of research where much progress has been made in the last decade. Contrary to the situation in animals and plants little is known about how diversification rates have evolved in most major groups of protist. This is mainly due to un...
