In 2006, John Brookfield was invited to comment on the Chicken or the egg controversy, along with a number of others. All parties came down on the egg first side of the debate. John gives his reasoning as "The first chicken must have differed from its parents by some genetic change, perhaps a very subtle one, but one which caused this bird to be the first ever to fulfil our criteria for truly being a chicken. Thus the living organism inside the eggshell would have had the same DNA as the chicken that it would develop into, and thus would itself be a member of the species of chicken."
To further public understanding of evolutionary genetics, John Brookfield has created a podcast explaining some of the issues, and as part of the Nottingham University 200 years of Darwin Celebrations, delivered Darwin's famous lecture On the Origin of the Species, in full Victorian dress. He has additionally written in the media about DNA profiling.

Famous quotes containing the words popular and/or science:
“There is a continual exchange of ideas between all minds of a generation. Journalists, popular novelists, illustrators, and cartoonists adapt the truths discovered by the powerful intellects for the multitude. It is like a spiritual flood, like a gush that pours into multiple cascades until it forms the great moving sheet of water that stands for the mentality of a period.”
—Auguste Rodin (1849–1917)
“We are living now, not in the delicious intoxication induced by the early successes of science, but in a rather grisly morning-after, when it has become apparent that what triumphant science has done hitherto is to improve the means for achieving unimproved or actually deteriorated ends.”
—Aldous Huxley (1894–1963)
