No, this is not Lysenkoism. In lysenkoism the environment changes the genes. Here there is no change in genes. The human genome (and that of animals of course) adapts to the environment and reacts with it. You notice it all the time. If it is hot, you sweat to cool the body down. Plants are also affected by the environment. If they have a small pot, they will grow small, if they have a big pot, they will grow big. Same for goldfish. This is all part of the marvelous design of the Creator.
