False, Darwin was just the most famous one to do it.
Genetic engineering:Pros: produces more food, makes organisms more fit, increases knowledge and knowledge is good.Cons: Some say it's: playing God, dangerous due to recombination of DNA, contamination of the gene pool, big pharma could take over the "means of production".
In-vitro fertilization: Pros: Allows people who couldn't have children to do so, increases knowledge and knowledge is good.Cons: Expensive (really expensive), can lead to overpopulation (minor), can be done irresponsibly (minor as everything can be).
