Since the end of the ice age around 11,000 years ago, the climate had been changing and gave the annual plants advantage to grow from seeds and tubers with built in energy reserves to following generation of plants. Mankind took advantage of this by harvesting and storing food supplies.
This fact help humanity to preserve and as we settled down we developed agriculture, domesticating the firs plants and animals; this early farmers observed the way things grew and reproduced. Then, they started choosing the biggest and healthiest plants seeds to grow the next generation, this is selecting breeding, and these were the first genetic engineers.

PROS and CONS of Transgenic crops: Economic Considerations. Improved Crop Productivity in Poor Areas The ability to boost agricultural production for poor populations and/or in poor soil or difficult growing climates is one of the stated goals of many plant researchers engaged in this work. A 2003 book edited by Nicholas Kalaitzandonakes, The Environmental and Economic Impacts of Agbiotech: A Global Perspective suggests that some progress toward increased productivity has been made. The book, which compiled a variety of research papers, found that insect-resistant and herbicide-tolerant technologies are reducing the risk of crop losses. In addition, progress is being made toward developing transgenic varieties that are drought-tolerant (especially important for parts of Africa); UV-tolerant (able to withstand the sun 's ultraviolet radiation at high elevations in the Andes or Himalayas); or virus-tolerant. POTENTIAL to PRODUCE MEDICINES INEXPENSIVELY Transgenic plants have the potential to produce pharmaceuticals at modest expense. Currently, transgenic bacteria produce most of the insulin to meet the needs of diabetics in the United States. In a similar vein, plants could be used to grow vaccine ingredients.
