Werner Arber, Nobel Laureate 1978: Interestingly, naturally occurring molecular evolution, i.e. the spontaneous generation of genetic variants has been seen to follow exactly the same three strategies as those used in genetic engineering14. These three strategies are: (a) small local changes in the nucleotide sequences, (b) internal reshuffling of genomic DNA segments, and (c) acquisition of usually rather small segments of DNA from another type of organism by horizontal gene transfer.

However, there is a principal difference between the procedures of genetic engineering and those serving in nature for biological evolution. While the genetic engineer pre-reflects his alteration and verifies its results, nature places its genetic variations more randomly and largely independent of an identified goal. Arber, W.

The number of insecticide applications was significantly higher in nonTr than in transgenic cotton in 2002 (one-tailed contrast, t 4.13, df 72, P 0.0001) (a) and in 2003 (one-tailed contrast, t1.99, df72, P0.025) (b). The number of insecticide applications was higher in 2003 than in 2002 (P0.058), although differences in insecticide applications among cotton types did not vary between years (P 0.47).
Figure 3. Anti-herbivore effects of transgenic plants. (A) Tobacco cutworm (S. litura) larvae at the third instar were allowed to feed on six leaf dics, three from caffeine producing, and three from control plants. Bar indicates 5 mm. (B) Leaf disc choice test. After feeding for 3 h in the dark, each disc was collected and photographed. Two transgenic lines were tested; lines #1 (Test 1) and #2 (Test 2) contained caffeine at 5 lg and 0.4 lg per g fresh weight, respectively. Disc samples are from caffeine containing (1 and 3) and control leaves (2 and 4). (C) Quantification of feeding behavior. Twenty replicate tests were performed for one transgenic plant as described above, and fed leaf areas (vertical axis) were calculated with the aid of an image analyzer. The horizontal axis indicates the duplicated test (Test 1 and Test 2) with discs from caffeine containing (1 and 3) and control leaves (2 and 4), respectively. Some tests which showed no feeding were excluded from the evaluation. Uefuji, H., Tatsumi, Y., Morimoto, M., Kaothien-Nakayama, P., Ogita, S., & Sano, H.

make peace between organic farming and biotechnology
The national percentage of cropland planted with conservation tillage technology surpassed the percentage of plowed ground in 1997. Indiana was one of the top five contributors to the increase in acreage farmed with the erosion-busting technology. Here a farmer plants into corn stalk residue.
