"The human parathyroid glands, which regulate the level of calcium in the blood, probably evolved from the gills of fish, say researchers.
The gills of ancestral marine creatures were used to regulate calcium levels.
A team from King's College London believe that they were internalised, rather than lost, when four-limbed, land-living animals evolved.
The research is published 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.

Calcium plays a key role in many physiological processes, such as muscle contraction, blood coagulation and signalling by nerve cells. "
I cannot remember where and when I read it, but I'm certain that at some point the baby fetus resembles a fish early on... or is it a worm... or a tadpole????? I'm confused.
