Earthworm poo could turn into a rather valuable dating tool
Over a hundred years after Darwin’s fastest-selling book  hit the racks, scientists are finding that individuals are underestimating the earthworm’s share to your global carbon period. Mark Hodson explores.
Science careers are funny things. Fifteen years ago I finished my geology PhD on why some igneous stones regarding the tip that is southern of have actually stripes. During the right time, earthworm poo had never entered my brain.
If some body had said then that 10 years or more later on Denise Lambkin, my postdoc, and I also would invest significant amounts of time sifting through earthworm poo i might have thought they certainly were having fun.
But my tale begins much sooner than this. It surely started in 1881. After a lot more than 40 many years of observation, Darwin finished and published their last great work ‘The formation of veggie mould, through the action of worms, with observations on the habits’. As a sign of Victorian reading tastes, the guide offered quicker than ‘ On the foundation of species’, at the least in the first place.
My collision with Darwin’s great text actually dates back to 2002. I’d been focusing on exactly just just how pollution that is metal contaminated soils impacts earthworms for the simple couple of years once I discovered myself at an International Earthworm Symposium in Cardiff.
