Cancer, SARs, etc are significant macroeconomic concerns.
Bats are long lived and resistant to cancer and pathogens like SARs.
{ The new study shows that the “little brown” bat (Myotis lucifugus) carries two working copies of the key tumor suppressor gene p53, while humans carry only one. }
If one copy becomes “non-functional” the other, STILL FUNCTIONAL copy, continues to protect against cancer.
This is similar, in concept, to x-linked (Sex linked) genetic conditions such as red-green color blind, hemophilia, muscular dystrophy, etc.
These are usually found in males, who have only 1 (one) copy of a gene located on the x chromosome. There is no “second” copy, to on the y chromosome, that can produce a functional phenotype.
Recently CRSPR tech was used to “correct” a non-functional gene in a baby’s liver cells.
Chinese twins were GMOd a few years ago, to prevent HIV.
Can science add a second P53 to the human genome?
