Researchers in a
of fields collaborated in the
. They included computational
biologist Jörg Schultz and plant
Rainer Hedrich. They sequenced and compared the genomes of carnivorous plants to non-carnivorous
. They discovered that meat-eating plants developed from the
common ancestor about 60 million years ago. Dr Schultz said: "We were able to trace the
of carnivorous genes back to a duplication event that occurred
millions of years ago in the genome of the last common ancestor of the carnivorous species." Dr Rainer added: "The
of these genes is related to the ability to sense and digest animals and to utilise their
."
