tl;dr Scientists injected RNA of previously shocked snails into normals snails and they exhibited same reaction to shock as shocked snails.
Counterargument:
A more plausible explanation is that "injected RNA" was contaminated with chemicals released by snails during stress.
Also:
>not using mice
>some shady "RNA material"
>only 5 snails per group
They should replicate the experiment with something less obvious(stress is really blunt instrument).
1.Use mice/rats
2.Use at least 40 per group.
3.Check the RNA material for contamination.
4.Space injections in time, biological clocks can influence hormones at time of injection.
