I was disturbed that there was nary a mention of plants, however. People have been cloning plants for millennia, and botanists have long known that virtually all plant cells are totipotent. Zoologists may think that, provided they are ignorant of plant science, but botanists have long used the word in a perfectly scientific way and with no reference to nuclear transplantation. A clone can consist of a single individual, but populations are more common.
Identical twins are a clone formed from a single fertilized egg.
Frank B. Salisbury Professor of Plant Physiology Utah State University Logan, Utah Cellular rejuvenation will lead ultimately to the rejuvenation of specialized adult cells. Nearing age 50, I could use some totipotency. If that represents U.S. use, it requires a per capita consumption of about 1 ton of detergent. In my household, we use only 1.5 percent of that amount. If the figure represents worldwide household use, it implies that every person on the planet uses three times more detergent and cleaning products than we do.
