Scientists force evolution? Maybe the folks over at LiveScience need to evolve their reporting. Adaptation isn’t evolution. Polypheniesm is typically environmentally caused; color change induced by environmental variations is to be expected.
Let’s look at ourselves, as example of where LiveScience falters. Homo Sapiens is considered to be one species, right? But there are different races, which, to my understanding aren’t considered subspecies. Racial variations would appear to have derived from environmental causes long ago.
