It's really not useful to throw out assertions based on a misunderstanding of the terms. NO, the Egyptians didn't practice genetic engineering. If you'd bother to look the term up you'd find that it means:
"Genetic engineering, also called genetic modification, is the direct manipulation of an organism's genome using biotechnology. New DNA may be inserted in the host genome by first isolating and copying the genetic material of interest using molecular cloning methods to generate a DNA sequence, or by synthesizing the DNA, and then inserting this construct into the host organism. Genes may be removed, or "knocked out", using a nuclease."
It would be equally useless had you said "god practiced genetic engineering by making people out of lumps of clay." Yeah sure. Once again, read the definition.
Contemporary Genetic Engineering/modification is quite different from selective breeding for many important reasons.
1) You can't breed a Jellyfish with a tomato by natural methods, however with modern gene splicing you can indeed.
2) GM varieties are being developed specifically to sell chemicals such as "Roundup" herbicide. Thus the plant will live even when drenched in this weed killer, and then ends up on YOUR plate. This isn't Darwin's natural selection, this is ruthless capitalism at the expense of your health.
3) Have you wondered why suddenly more and more people are buying "gluten free" products? Think it's just a fad? Coincidentally an unapproved-for-human-consumption genetically modified wheat was developed that produces its own pesticide. It kills insects by making perforations in their gut. This and several other unapproved GM crops have been "accidentally" released into the wild and have infected virtually all of the US primary crops.
