Walker says that Directed Evolution is different than Gain-of-Function, which is defined as “a mutation that confers new or enhanced activity on a protein.” In other words, it means that a virus such as COVID can become more potent depending on the mutation / scientific experiment performed on it.

If we're gonna do that though, there's a risk of like, as you could imagine -- no one wants to be having a pharma company mutating f**king viruses,” Walker said.
