It normally takes about 21 days for chicken embryos to develop into chicks. By observing chicken hindlimb formation, researchers from the CNRS / the Université de Paris has now discovered that the mechanism behind embryonic development consists of a sequence of reflexive contractions. The researchers were also able to artificially recreate the same process and accelerate it by as much as a factor of 20. Their findings have been published in the European Physical Journal.
