History Charles Darwin listed a number of putative human vestigial features, which he termed rudimentary, in The Descent of Man (1871). These included the muscles of the ear; wisdom teeth; the appendix; the tail bone; body hair; and the semilunar fold in the corner of the eye.

In animals that contain coelomic fluid instead of blood, oxygen diffuses across the gill surfaces into the coelomic fluid. Gills are found in mollusks, annelids, and crustaceans. Figure 39.2.1 39.2. 1: Common carp: This common carp, like many other aquatic organisms, has gills that allow it to obtain oxygen from water.

Human Ears Evolved from Ancient Fish Gills News By Bjorn Carey published 19 January 2006 This image shows how the hyomandibula receded in fish to create a wider ear opening in early land.

Designer Jun Kamei has created the prototype of 3D-printed "gill" that may allow humans to breathe underwater. Called Amphibio, will the bold project becoming a living, "breathing" reality?

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**.

Artificial gills (human) Artificial gills are unproven conceptualised devices to allow a human to be able to take in oxygen from surrounding water. This is speculative technology that has not been demonstrated in a documented fashion.
Curious kids how do gills work? Evening Report
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.

Humans With Gills
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.]

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.

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.
