Maciej Giertych signed his Correspondence letter (Nature 444, 265; 2006) as an employee of the Institute of Dendrology, the Polish Academy of Sciences. As the director of the institute, I would like to point out that, although I respect Professor Giertych's rights to express his views, they are not endorsed by our institute. In my opinion, creationism has no basis in science and should not be regarded as scientific.
