Macroevolution has not been observed. Yes, i have seen the above articles many times such as the lizards. These lizards just changed size, head shape and colour etc., but they were still morphologically clearly lizards. They didn't evolve into something else: "As a result, individuals on Pod Mrcaru have heads that are longer, wider and taller than those on Pod Kopiste, which translates into a big increase in bite force", head shape changes has also been observed in human populations within historic times, but the end product was still human.
