For gills to be remotely useful for something with our metabolism and average size they'd need to be enormous and have a very direct blood supply, so probably both sides of the thorax. Your chest would be mostly gills, and that's not workable. 3 mmomtchev • 3 yr. ago

Gareth Bartlett Have you ever noticed someone with tiny holes above their ears? In the UK, just under one per cent of people are born with them and it's called preauricular sinus.

For humans and other mammals who hiccup, it has no value but does provide another bit of evidence of our common ancestry. Dr Michael Mosley presents Inside the Human Body, Thursdays, 9pm, from 5.
Humans With Gills
First, and most obvious, is that fish possess gills that have evolved to absorb oxygen while keeping out waste gases; human respiratory systems are equipped to tap into the oxygen in the air..

Gills are best known for helping most fish species breathe underwater. But less well known is the fact gills regulate the salt and pH balance of fishes' blood, a vital role played by the kidneys in other animals. Collectively known as ion regulation, this lesser-known gill function has been traditionally thought to have evolved in tandem with breathing.

A gill is a respiratory organ found in many aquatic organisms that extracts dissolved oxygen from water and excretes carbon dioxide. The gills of some species, such as hermit crabs, have adapted to allow respiration on land provided they are kept moist. [Emphasis added.]

In mammals, they go on to form the structures of the head and neck, but in fish they also help develop into their gills. It's this odd connection that led Neil Shubin, an evolutionary biologist.

The palmar grasp reflex is a characteristic behavior of human infants, developing as early as 16 weeks gestational age, when the fetus begins to grasp the umbilical cord in the mother's womb. Early research found that human newborns, relying on their grasp reflex, could hold their own weight for at least 10 seconds when hanging by their hands.

In fish, each gill slit has an accompanying set of blood vessels (5 in most sharks - at Massey we used to dissect them out as part of first-year bio labs). Lewis Held (2009) comments that. Human embryos go to the trouble of making five pairs of aortic arches (which once sent blood to five pairs of gills) but then destroy two of them completely**.
