Neil deGrasse Tyson Tells GMO Critics to "Chill Out"

[wandy]

64. I think I understand this...........

It would be similar to "porting" code from one program into another. If a group of sub routines work well in program "A" and are superior to similar routines in program "B" their is no reason not to reuse them. It is done all the time.
The thing to keep in mind is that the end result must be tested to insure nothing was broken in the process. Even 'minor' changes can require "BOX" test cycles that can be longer than the lives of a few generations of fruit flies.
If the program/device works in conjunction with other programs/devices further system environment testing must be performed to insure the 'end product' does not exhibit undesirable results in the "real world".

Here lies my concern.
Splicing spider DNA into a cow may produce a happier bovine but what effect will the decaying cow have on, or say, caterpillars.
How do we predict/test for the over all results.
DDT,agent orange, roundup, Windows VISTA may be proof that we sometimes become careless or at best miss our guess.

A true believer that the fluttering of a butterfly's wings in Brazil may influence a hurricane in the Atlantic.
