Changing the Blueprints of Life - Genetic Engineering: Crash Course Engineering #38

video description

Rating: 4.0; Vote: 1
Can we change the blueprints of life? This week we are exploring that question with genetic engineering. We-ll discuss how selective breeding can improve agricultural practices, and the potential DNA-level engineering could have on other fields of engineering. We-ll also look at how optogenetics and CRISPR have opened up new ways for genetic engineers to change the DNA inside living cells. Crash Course Engineering is produced in association with PBS Digital Studios

Genetic Engineering of Human DNA is THE MOST DANGEROUS ENDEAVOR HUMANITY COULD POSSIBLY EVER UNDERTAKE. This does not extend to GMOs and I wish people would tale their heads out of their asses about this. There is NOT ONE food crop that humans eat today that resembles the ancestor foods of 12, 000 years ago. The most prolific that no one talks about apples. In the U. S. there are 2, 500 varieties of apples with 100 used commercially. If apples in every new season were not spliced with apple flowering stock from the previous season, no two seasons of apples from the same tree would taste the the same. Yams are still manipulated in the same way they have been for 12, 000 years, olives for 10, 000 years. There is no farmed foods that are not in one way or another genetically modified. If we didn-t, humanity would have died out millennia ago.
As to human DNA MANIPULATION will start innocent enough, correcting for various developmental disorders. It will first get dark with selective abortion of -undesirable- traits in unborn children. It will quickly, with in 5 to 10 years, first by the military then by the wealthy designer babies. Babies engineered for specific characteristics. At some point, and soon within the first 15-20 generations, there will be so much divergence from the rich designing babies, there will be millions of people who incompatible mates for anyone else on the planet, they are so unique. Eugenics cold wars WILL flare all over the world. Government funded and the rich will have -Super babies- who as teens will be well aware of just how superior they are and will very likely go to war for dominance, wipe each other out, or wipe out the lessers, the poor who could not afford genetic modification. This is Pandora-s Box Personified. The only tech close to the same league is truly Self Aware, Emotional, A. I.
We are in an era where the race to better tech has outstripped our ability to use Good Judgement, Reason and Logic to truly decide if, just because we can do a thing, should we do that thing? Government and self absorbed, and yes I-m going there, atheist scientist who believe science for the sake of science is the height of human endeavor, will ignore safe guards or whether we should do a thing. Atheist do believe in a god, science and the human mind. They are hardly true atheists, Humanists perhaps.

As an intuitive empath, that is in laymans terminology, pychically gifted. Yes, no need to be put through a crisper, --. To the laymen out there who listen to this type of propaganda. to play with the human brain/cellular level. .its called thought (a natural process) and thought can/does cause our cellular structure to mutate in fact. more so than our environment. it CAN happen over a single lifetime. REMEMBER Darwin's theory is JUST a theory. change happening over millennium. -. he never put into play the aspect of thought just environmental but then his thinking was limited to the FIVE senses, ESP does help see through the bull---- given, whether in -the name- of science or politics.
The moment humans play God they think they are a -god- we are mutating naturally WITHOUT the need for a fellow human being playing around with genetics. yes some things have occured that are -good- yet the SIDE EFFECTS are astronomically dangerous. its called ethics. its not what is spoken of here it is WHAT is not said. so do your own research NOT what is brought to you via technocracy and yes big pharma is a major aspect of technocracy.
Maybe one day science can catch up to what we physically talented individuals already know, but they gotta go about it the hard, arduously difficult way. some are researching. the smart scientists are that is, into phychic phenomon.

If our world is any indication of human development.
Genetic engineering shall be most interesting. especially when the natural world selection is for the strongest and smartest or most adaptable of the species in aggregate.
Creating species by unnatural selection for the Ultimate purpose of immortality research sounds like a petri dish in da sky reach. lmao
Also the sugarphospate backbone is an electrically neutral electron carrier chassis with minimal interference of the hydrogen nitrogen oxygen carbon recombination for ATCG

I have a question, when I hear about genetic engineering in humans it's always in the embryo stage, what are the obstacles stopping genetic engineering (other than ethics) in adults. I always figured that with CRISPR you can use a virus as a delivery method throughout the body by injecting the modified virus straight into bone marrow. Could someone explain please!

I never liked how cross breeding is lumped into today's genetic engineering as though it's the same thing when it isn't.
There are countless things you can do with genetic engineering that can never be achieved by cross breeding. This includes inserting genes from completely different species hench the moniker, Franken Food.

I find it shocking that most people seem to think living forever is a good thing. It only makes sense if we decide that the children do not deserve a future. If anything, our lives today are far too long for the good of both the planet and society.

0: 30 --That can sound a little scary, and it's certainly not without it's controversy-- < And why not? Unlike conventional engineering, you are creating something that will go on self-replicating, forever.

i don't care about making super humans with immune to everything! i want to know how to, combine animal DNA with another and make some kind of hybrid! which for me is much more interesting.

Crash courses are really badly directed. The teachers are like speakers gives me earache. Slower, more wise and more relax plz. Being fast does not mean to have rush in speaking!
reply

To me there should be no boundry to genetic engineering. If I could make my child healthier or more intelligent I would. I know I'd be upset if my parents passed that up for me.
