During the transformation protocol we apply heat shock to bacteria to make them take up plasmids from their environment. It is really useful in the lab.
However, it presents an evolutionary paradox in a bigger context, if bacteria begin to take up free floating plasmids on distress, they will most likely acquire genes from the other bacteria, who perished in the same distress, so those genes most likely will not be useful against their adversity.
I am sure there are other factors here to resolve this paradox. What are they?
