A benefit of genetic engineering is the production of valuable proteins that have helped in managing of illness in human beings. Bacteria were genetically engineered to produce proteins of medical importance. One example of such a protein is human insulin which is given the name humulin and is made using E. coli bacteria.Earlier, insulin from pig cells was used to treat patients with diabetes but many of them could not tolerate it because it has a slightly different arrangement of amino acids from that of humans and so the human body rejects it. Humulin is tolerated by the human body and so many patients are now using it to lead normal lives.
Taking all of them out of their natural environments would disrupt the ecosystem and food chains, and it would be difficult, if not impossible, to place more than a small portion of Earth's endangered species in these facilities.
If it's two different kinds of birds it's called competition.
Partly genetic from body type, but most of it has to be acquired to be able to be good at athletic abilities <span />
