Hans Larsson, Canada Research Chair in Vertebrate Palaeontology, speaks with Canada AM from CTV studios in Montreal, Monday, Aug. 24, 2009.
A paleontologist in Montreal plans to manipulate chicken embryos to give them dinosaur features, a first step towards hatching live prehistoric animals.
Hans Larsson told CTV's Canada AM the first chicken embryo with a range of dinosaur traits could be made within five years. However, that depends on the project receiving adequate funding, said Larsson, a 38-year-old professor at McGill University.
By flipping certain genetic levers at the appropriate point in a chicken embryo's development, Larsson believes he can instill features that disappeared from birds millions of years ago.
"We should be able to regenerate or essentially make the genetic program mimic the way it was at say, 150 million years ago, and grow a longer tail, change its plumage to something a little bit more primitive, have three-clawed fingers, some teeth," he said.
The idea for the project came about over a discussion with internationally renowned American paleontologist Jack Horner. Among other things, Horner served as technical adviser for the Jurassic Park films.
The two were talking about how to illustrate evolution. They decided that altering the development of chicken embryos could be "a very public, visual way of doing that," Larsson said.
"The fundamental questions are animal development. We're trying to find out what genes are turning on and off, how cells are moving within the embryo."
