Specifically the applicant will test: if 1) newly formed species differ in the distributions of epigenetic marks across the genome, 2) genomic variants linked to phenotypic divergence among species are in genomic regions unusually high in DNA methylation, as expected under a hypothesis of epigenetic differences preceding fixed nucleotide differences during adaptive divergence, 3) genomic regions diverging in patterns of methylation among incipient species are also exhibiting high levels of methylation in populations of Astatotilapia calliptera, the ancestral, colonizing species.

One aspect of SPH is that it casts the levels as developmental stages with irreversible trajectories of individuation (think of the incipient species becoming a [humanly] recognized species which ultimately gives rise to another species lineage).
