Article reads: In seeking to better understand how teosinte gave rise to corn, a scientific team has pinpointed one of the key genetic changes that paved the way for corn’s domestication. As reported today (Sept. 25) on the Nature Genetics website, a major change occurred about 23,000 years ago, when a small piece of DNA — a jumping gene known as Hopscotch — inserted itself into the control region of a teosinte gene that affects plant architecture. This case is among the first to show that a jumping gene can cause alterations in gene expression that impact evolution.
