Gene expression phylogenies and ancestral transcriptome reconstruction resolves major transitions in the origins of pregnancy
K. Mika, C. M. Whittington, B. M. McAllan, V. J. Lynch
This study uses ancestral transcriptome reconstruction to trace the evolution of pregnancy in vertebrates, finding that maternal gene expression correlates with placental invasion and suggesting an early origin of hemochorial placentation in eutherians.
