As far as I can remember, the guppies’ appearance changed, depending on the environment they were plunged into, one with and another without predators. And that happened within a very limited time window and circumstance, so obviously those fish did not change into mammals, lol. There is a host of materials

clearly showing where the physical flaws in human physique come from, as we’re a relic of other creatures.

You just described adaptation not evolution. In order for it to be Evolution the species has to change from one kind to another so like from fish to feline or from mammal to reptile.

Evolution is a form of adaptation to the environment you inhabit. And sorry but I won’t be banging my head against the wall with you here by arguing for the sake of arguing and going round in circles, which your clearly love to do. Not my cuppa. All the best.

You can do all the linguistic gymnastics that you want, the fact of the matter is evolution is the changing of one kind of species into another and the example that you gave of the Guppies is not that. The guppy is still a guppy therefore is not an example of evolution.
