Should sex-ratio distorting parasites abandon horizontal transmission?

abstract：BACKGROUND:Genomic sequence analyses have shown that horizontal gene transfer occurred during the origin of eukaryotes as a consequence of symbiosis. However, details of the timing and number of symbiotic events are unclear. A timescale for the early evolution of eukaryotes would help to better understand the relations...
