MALE SEAHORSE SHARE SOMETHING WITH YOUR MOTHER.

Viviparity (live birth) has evolved more than 150 times in vertebrates and at least 23 times in fish, but the syngnathid fishes (seahorses and pipefish) are the only ones in which males becomes pregnant. They have evolved special brooding pouches that provide protection, gas exchange, osmoregulation and some nutrients to developing embryos.

A team of Australian researchers examined the genes involved in male pregnancy in the big-belly seahorse (Hippocampus abdominalis) and they found that seahorse pregnancy involves more than 3000 genes. Intriguingly, many of these same genes are involved in female pregnancy in mammals, reptiles and other fish, a striking example of convergent evolution.

Incredible.

Since the challenges of pregnancy are similar across phyla (or indeed sex), evolution has apparently recruited similar genes to carry out the task.
