From Macro to Micro in 5 Steps:  From Macro to Micro in 5 Steps Please read this slide. It speaks for itself and gives the necessary background to understand how genetic engineering can take place. Targeted Gene Replacement:  Targeted Gene Replacement Don’t worry about how scientists manipulate genes; that’s not necessary to know. Just understand they can use chemical 'scissors' to cut gene segments away from where they belong, then with other chemicals they can 'splice' those living, working segments anywhere else along a gene strand. This provides virtually limitless possibilities for new functions. Nuclear & Mitochondrial DNA:  Nuclear andamp; Mitochondrial DNA Apart from sperm, eggs, and red blood cells, every cell in our bodies carries our entire genetic package. It is mind-bogglingly small, with all the chromosomes (23 from each parent) stuffed into each cell’s nucleus (nuclear DNA—nDNA), while outside the nucleus floats mitochondrial DNA (mtDNA), inherited exclusively from females. Human DNA carries an improbable amount of 'defects,' over 4000. It is as if a great deal of cutting/splicing was done on us, and numerous mistakes were made. Cerebral Cortex Comparison:  Cerebral Cortex Comparison Along with 4000 goofs, the genetic manipulation apparently done on humans created many winners. A cerebral cortex is the deeply convoluted surface of a brain strongly linked to intelligence (lower right). A rat’s cerebral cortex, flattened out, would cover a postage stamp; a monkey’s, a postcard; a chimp’s, a page of typing paper; but a human’s covers four pages! As given the pre-human cranial shapes and capacities, this is far more like a 'transformation.' Three Primates and a Human:  Three Primates and a Human This shows the chromosome line-up for humans, chimps, gorillas, and orangutans. Note the remarkable similarity in much of their 'banding' arrays. However, humans carry only 46 chromosomes, while all other primates carry 48. Something is clearly wrong. If they are all so much alike in their banding, how could humans lose one? Better yet, WHY? How could removing one chromosome create such huge differences? Fusion of 2nd Chromosome—Wow:  Fusion of 2nd Chromosome—Wow Actually, the 'missing' chromosome isn’t missing at all. In humans the 2nd and 3rd chromosomes of all other primates have been carefully and deliberately fused. Of course, mainstream scientists explain this as a 'natural' mutation that just happened to occur at some point in our evolution. But the truth is that fusions like this are only seen in labs, where geneticists leave exactly the same kind of proofs of their efforts. Trying To Have It Both Ways :  Trying To Have It Both Ways The Mitochondrial Eve theory revealed in this Newsweek cover in early 1987 proves that humanity, as we are today, came into existence rather suddenly at 'only' about 200,000 years ago. Thus, we did not gradually evolve over millions of years. This has forced mainstream scientists to try to squeeze us through the same genetic 'bottleneck' used to explain away other anomalous species of domesticated plants and animals. The bottom line is: Humans didn’t evolve on Earth, and our genes prove it.
