Marine Evolutionary Biology

Why males and females exist and how sex roles have evolved belong to the most controversial issues in evolutionary biology. I examine the evolution of male pregnancy in pipefishes and seahorses (syngnathids) by comparing the genetic and immunological adaptations for the unique male pregnancy with female pregnancy evolution. Insight into joint and distinct loss of traits, involving the recruitment of genes with a different original task along with the establishment of novel genes, will help to unravel convergent evolution of parental investment and pregnancy.
