- Humans may still have gills.
- Scientists believe humans still have gills which were internalised, rather than lost, after our ancestors crawled out of the ocean.
- A team from King's College London believe human parathyroid glands, which regulate the level of calcium in the blood, probably evolved from gills.
- The gills of ancestral marine creatures were also used to regulate calcium levels, says a report in Proceedings of the National Academy of Sciences.
- This research suggests that in fact, our gills are still sitting in our throats - disguised as our parathyroid glands.
- Instead they increase their internal calcium concentration by using their gills to take up calcium from the surrounding water.

- --> Human gland probably evolved from gills.
- The human parathyroid gland, which regulates the level of calcium in the blood, probably evolved from the gills of fish, according to researchers from King’s College London.
- Writing in the latest edition of Proceedings of the National Academy of Sciences, Professor Anthony Graham and Dr Masataka Okabe suggest that the gills of ancestral marine creatures, which were used to regulate calcium levels, were internalised rather than lost when land-living, four-limbed animals – the tetrapods – evolved. ...
- Instead they increase their internal calcium concentration by using their gills to take up calcium from the surrounding water. ...
- ‘As the tetrapod parathyroid gland and the gills of fish both contribute to the regulation of extracellular calcium levels, it is reasonable to suggest that the parathyroid gland evolved from a transformation of the gills when animals made the transition from the aquatic to the terrestrial environment,’ said Professor Graham. ...
- The researchers supported their theory by showing that the parathyroid glands of mice and chickens and the gills of zebrafish and dogfish contain many similarities. ...
- Both gills and parathyroid gland develop from the same type of tissue in the embryo, called the pharyngeal pouch endoderm; both structures express a gene called Gcm-2, and both need this gene to develop correctly. ...
- Furthermore, the researchers found a gene for parathyroid hormone in fish, and they discovered that this gene is expressed in the gills. ...
- ‘The parathyroid gland and the gills of fish are related structures and likely share a common evolutionary history,’ said Professor Graham. ... This new research suggests that in fact, our gills are still sitting in our throats – disguised as our parathyroid glands. ...

- gills .
- In fishes the gills are located in gill chambers at the rear of the mouth (pharynx). Water is taken in through the mouth, is forced through openings called gill slits, and then passes through the gill clefts, spaces between the ranks of delicate gills, bathing them continuously. ... The gills, which may be platelike or tufted, are attached to the outer edges of a series of paired cartilaginous or bony gill (or branchial) arches. ... In the higher aquatic invertebrates the gills protrude from the body surface and contain extensions of the vascular system. In the crustaceans these external gills are covered by a protective carapace, part of the shell; in the echinoderms they are branched appendages extending from various parts of the body. In the mollusks the gills (called ctenidia) are internal and are located inside the mantle cavity. ... Amphibians breathe by means of external gills in their aquatic larval stage; a few forms retain the gills after metamorphosing into terrestrial adults. Aquatic insect larvae accomplish the oxygen-carbon-dioxide exchange by means of tracheal gills, projections from the walls of the air tubes (tracheae); these gills disappear when the insect leaves the water. ...
