Hens' teeth not so rare after all
Scientists have discovered that rarest of things: a chicken with teeth – crocodile teeth to be precise.
Contrary to the well-known phrase, 'As rare as hens' teeth,' the researchers say they have found a naturally occurring mutant chicken called Talpid that has a complete set of ivories.
The team, based at the Universities of Manchester and Wisconsin, have also managed to induce teeth growth in normal chickens – activating genes that have lain dormant for 80 million years.
Professor Mark Ferguson, one of the scientific team at the University of Manchester, says the research – published in Current Biology this week – has major implications in understanding the processes of evolution. It could also have applications in tissue regeneration, including the replacement of lost teeth in humans.
"The mutant bird has severe limb defects and dies before it can hatch," explained Professor Ferguson, who is based in the University's Faculty of Life Sciences.
