By increasing the degree of DNA methylation of a gene called Egfr - gene involved in controlling growth - they were able to create a spectrum of ants of different sizes. Methylation is a biochemical process that controls the expression of certain genes. Essentially, the researchers found that the more methylated the gene, the larger the size of the ants.

"By modifying the methylation of one particular gene, that affects others, in this case the Egfr gene, we could affect all the other genes involved in cellular growth," said study co-author Sebastian Alvarado from the McGill. "We were working with ants, but it was a bit like discovering that we could create shorter or taller human beings," Alvarado said.

Gene Modification May Change Your Height, Complexion
Researchers at McGill University have identified a key mechanism by which environmental factors influence traits like our height, skin colour, intelligence etc.
