Blackmore and Barnes (1987) hypothesized that two factors contributed to evolution of the
embryophyte spore wall; transfer of the sporopollenin wall from zygotes to meiospores, and the fusion of single lamina into multilaminate walls.
Phylogenetic relationships of the liverworts (Hepaticae), a basal
embryophyte lineage, inferred from nucleotide sequence data of the chloroplast gene rbcL.
Embryophyte spore walls: origin, development, and homologies.
Then, in the subsequent section, I will revisit the question of the origin of
embryophyte life cycles from the perspective of our modern understanding of the phylogeny of
embryophytes and their algal relatives.
1987) recognize the Charophyceae as "Charophyta," a division distinct from Chlorophyta, perhaps more closely related to
embryophyte plants (than other green algae).
In chapter one, "Evolutionary significance of bryophytes," the authors build a firm comparative morphological case regarding bryophytes as
embryophytes along with the other terrestrial plants, the vascular plants.

bryophytes: Are all
embryophytes ('land plants') that are non-vascular: they have tissues and enclosed reproductive systems, but they lack vascular tissue.

These two developmental processes have been described to occur in a broad spectrum of
embryophytes, from bryophytes to many flowering plant families.
